Don't forget to set up your conf file!
DESCRIPTION
Mail::Bulkmail 1.00 had a thing called "filemapping", it was to allow you to dynamically
populate certain variables into your message. Put in people's names, or the like.
2.00 renamed "filemapping" to the correct term - "mail merging", and also added in the
ability to dynamically create your message, if so desired. So you could very easily send
out completely different messages to everyone on your list, if so desired. But 2.00 also
added a *lot* of processing overhead, most of which was unfortunately in the form of
voodoo. i.e., I seem to recall lots of testing, debugging, etc. until I finally reached a
point where the code worked and I sent it off. Not quite sure how it worked, mind you, but
happy with the fact that it worked nonetheless.
3.00 strips that ability out of Mail::Bulkmail, cleans it up, and places it here. This has
a few advantages. For one thing, if you're not doing any mailmerging, then you don't have
to worry about any of the overhead of building hashes, doing checks, internally handling
things, and so on. There wasn't a tremendous amount of useless work done in that case, but
it was enough to be noticed. So now use Mail::Bulkmail if you're not doing mail merges,
and Mail::Bulkmail::Dynamic if you are.
And the other thing is that the code is cleaned up a lot. I actually know and understand
how it all works now, and it functions much better than previous versions did. Faster,
more efficient, and so on.
ATTRIBUTES
log_all_data
boolean flag, 1/0.
Mail::Bulkmail has an easy job logging its list items - they're always
guaranteed to be single email addresses. Mail::Bulkmail::Dynamic has a harder
time, since it's usually an email address and some other data.
'jim@jimandkoka.com::Jim Thomason::24'
or
['jim@jimandkoka.com', "Jim Thomason", "24"]
or
{
"BULK_EMAIL" => 'jim@jimandkoka.com',
"name" => "Jim Thomason",
"age" => "24"
}
Most of that is obviously not simple scalar data and needs to be logged
differently. If log_all_data is set to 0, then only the email address will be
logged and everything is fine. However, if log_all_data is 1, then a hashref
containing all of the data is returned (regardless of the type of data
structure you initially handed in). Obviously, you will then need to deal with
logging yourself, either by logging to an arrayref or (better) to a function
call. Logging to a file with log_all_data set to 1 will just give you a useless
list of "HASH(0x7482)" and the like.
All pieces may be used simultaneously. So in one mailing, you can use
merge_keys, dynamic_message_data, dynamic_header_data, and global_merge.
merge_keys This should be much easier to use and understand than it was in prior versions.
Okay, let's start off with the simple case, you have a file that contains a
list of email addresses:
foo@bar.com
bob@hope.com
john@junior.com
And you set up a list with Mail::Bulkmail to mail to them. Your message is
something like this:
"Hi there. Things are great in my world, how's yours?"
This works fine for a while, people are happy, everything's dandy. But then,
you decide that it would be nice to personalize your email messages in some
fashion. So you switch to Mail::Bulkmail::Dynamic. You'll need more
information in your list of addresses now.
foo@bar.com::Mr. Foo
me@there.com::Bob Hope
john@junior.com::John Jr.
And then you'll need to define your merge_keys. merge_keys is an arrayref that
defines how the data in your file is structured:
merge_keys => [qw(BULK_EMAIL <<NAME>>)]
That tells Mail::Bulkmail::Dynamic that the first item in your list is the
email address, and the second one is your name. Please note that the email
address MUST be called "BULK_EMAIL", that's the keyword that the module looks
for to find the address to send to. The rest of your keys may be named anything
you'd like, but avoid naming keys starting with "BULK_", because those are
reserved for my use internally and I may add more special keys like that in the
future.
(You'll also need to make sure that your merge_delimiter is set to "::", see
merge_delimiter, below).
Now you can change your message to the following:
"Hi there, <<NAME>>. Things are great in my world, how's yours?"
This will send out the messages, respectively:
Hi there, Mr. Foo. Things are great in my world, how's yours?
Hi there, Bob Hope. Things are great in my world, how's yours?
Hi there, John Junior. Things are great in my world, how's yours?
And voila. Customization. you may include as much data as you'd like:
merge_keys = [qw(<<NAME>> BULK_EMAIL <<STATE>> <<AGE>> <<HOBBY>> <<PREFERRED COMPUTER>>)]
#in your list:
Jim Thomason::jim@jimandkoka.com::IL::24::Programming Perl::titanium powerbook
#and then your message.
Dear <<NAME>>,
How've you been? I see that your email address is still BULK_EMAIL.
Are you still living in <<STATE>>? And you're still <<AGE>>, right?
Do you still enjoy <<HOBBY>>?
Well, email me back a message from your <<PREFERRED COMPUTER>>.
And that's all there is to it. Just be sure to remember that any keys you
define will get clobbered *anywhere* in the message.
merge_keys => [qw(BULK_EMAIL name)]
LIST => [qw(jim@jimandkoka.com::Jim)]
"Hi there, name. I've always liked your name."
You *probably* want that message to populate as:
"Hi there, Jim. I've always liked your name."
But it will populate as:
"Hi there, Jim. I've always liked your Jim."
Which doesn't make sense. So just make sure your keys aren't anywhere else in
your message. For example,
merge_keys => [qw(BULK_EMAIL <name>)]
LIST => [qw(jim@jimandkoka.com::Jim)]
"Hi there, <name>. I've always liked your name."
Your list data may be a delimited scalar, as we've been using in our examples:
jim@jimandkoka.com::Jim::24
Or an arrayref:
['jim@jimandkoka.com', 'Jim', '24']
In both of those cases, the order of the data is important. Each data element
matches up to a particular key. So be sure that your data is actually in the
same order as defined in your merge_keys array.
Alternatively, you can also just store your data in a hash and pass that in:
{
'BULK_EMAIL' => 'jim@jimandkoka.com',
'<name>' => 'Jim',
'<age>' => '24'
}
This is the one case where your merge_keys values will be ignored, and a
mailmerge will be done with the key/value pairs passed in that hashtable.
Passing in a hashtable is the fastest in terms of internal processing, but
there may be additional work on your end to generate the hash. When reading
from a file, you should always use delimited strings (since that's what'd be in
your file anyway), but from other sources you can experiment with hashrefs or
arrayrefs and see which is faster for your uses.
mail merges apply to both message and header information. So it's valid to do:
$dynamic->Subject("Hello there, <name>");
And have the mail merge pick that up.
Note that the merge will be performed in an arbitrary order, independent of
what's specified in merge_keys. So don't expect to have one piece of the merge
populate into your message before another one.
merge_delimiter
If you're reading in from a file, you can't have arrayrefs, hashrefs, whatever.
They don't store nicely in text. So your data will probably be a delimited
string. In that case, you need to know the delimiter. Set it with
merge_delimiter.
#in your list
jim@jimandkoka.com::Jim
#then
$dynamic->merge_delimiter("::");
#in your list
jim@jimandkoka.com-+-Jim
#then
$dynamic->merge_delimiter('-+-');
#in your list
jim@jimandkoka.com,Jim
#then
$dynamic->merge_delimiter(',');
Just be sure that your delimiting string occurs *only* as the delimiter and is
never embedded in your data. No escaping of a delimiter is possible.
global_merge
It can be useful to to do a mail merge with non-address specific data. For
example, you may want to put today's date in your subject. But it's silly (if
not impossible) to populate that data out to all of your addresses. This is
where the global_merge comes in.
$dynamic->global_merge(
{
"<DATE>" => scalar localtime
}
);
or, at creation:
my $dynamic = Mail::Bulkmail::Dynamic->new(
"global_merge" => {
"<DATE>" => scalar localtime
}
);
<DATE> will now change to today's date in your message.
"Hello, list member. This is the list for <DATE>"
This is a hash table that populates merge data before individual mail merge
items. There is no way to use the same key for both a global_merge and a per-
address merge. The global merge will always pick it up and the individual merge
will miss it. So, as always, use different keys.
dynamic_message_data
Mail merges are all well and good, they store unique information about a unique
email address. But sometimes you want to group together several users and send
them the same information based upon some other criteria. That's where
dynamic_message_data comes in handy.
This is probably easiest explained via examples. dynamic_message_data is a
hashref of hashrefs, such as this:
$dynamic->dynamic_message_data(
{
'<agegroup>' => {
'over70' => 'napping',
'40-50' => 'amassing wealth',
'20-40' => 'working',
'under20' => 'playing'
},
'<animallover>' => {
'hates_animals' => "I see you hate animals.",
"likes_animals" => "I see you like animals.",
"loves_animals" => "I see you love animals."
},
'<personalized>' => {
'yes' => 'Hi there, <name>',
'no' => 'Hi there'
}
}
);
Now then, your merge keys could be defined as such:
->merge_keys([qw(BULK_EMAIL <name> <age> BULK_DYNAMIC_MESSAGE)]);
Your list would be:
foo@bar.com::Mr. Foo::23::<agegroup>=20-40;<animallover>=hates_animals;<personalized>=yes
me@there.com::Bob Hope::78::<agegroup>=over70;<animallover>=likes_animals;<personalized>=no
john@junior.com::John Jr.::14::<agegroup>=under20;<animallover>=likes_animals;<personalized>=yes
And finally, your message would be:
<personalized>. Judging by your age, which is <age>, you should enjoy <agegroup>.
Oh, and <animallover>
The messages sent out would be, respectively:
Hi there, Mr. Foo. Judging by your age, which is 23, you should enjoy working.
Oh, and I see you hate animals.
Hi there. Judging by your age, which is 78, you should enjoy napping.
Oh, and I see you like animals.
Hi there, John Jr.. Judging by your age, which is 14, you should enjoy playing.
Oh, and I see you like animals.
See? easy as pie. Your dynamic message should be specified in your merge_keys
as BULK_DYNAMIC_MESSAGE, and should be a delimited string (in this case).
agegroup=20-40;<animallover>=hates_animals;<personilized>=yes
You can specify what delimiters you'd like to use. In this case, your
dynamic_message_delimiter is ';', and your dynamic_message_value_delimiter is
'='.
More clearly, this information translates to the following:
<agegroup> => 20-40
<animallover> => hates_animals
<personilized> => yes
Please note that angle brackets are not required, they're just useful for
clarity in our example. This is also perfectly acceptable:
$dynamic->dynamic_message_data(
{
'agegroup' => {
'over70' => 'napping',
'40-50' => 'amassing wealth',
'20-40' => 'working',
'under20' => 'playing'
}
}
);
me@there.com::Bob Hope::78::agegroup=over70
As long as you use the same keys, you're fine.
So you should be able to easily see that we'll look up the message associated
with being in the agegroup of 20-40, the animallover that hates_animals, and
then personilized with a choice of 'yes'.
Dynamic message creation is done before mail merging, so you are more than
welcome to put mail merge tokens inside your dynamic message, as we did above
with the "<personalized>" token, which may include the mail merge token of
"<name>".
Don't use the same tokens for mailmerges and dynamic messages, since the system
may get confused.
Alternatively, instead of a delimited string, you may pass in an arrayref of
strings:
[qw(agegroup=20-40 <animallover>=hates_animals <personilized>=yes)]
or an arrayref of arrayrefs:
[[qw(agegroup 20-40)], [qw(<animallover> hates_animals)], [qw(<personlized> yes)]]
or a hashref:
{
agegroup => 20-40
animallover => hates_animals
personilized => yes
}
Passing in a hashtable is the fastest in terms of internal processing, but
there may be additional work on your end to generate the hash. When reading
from a file, you should always use delimited strings (since that's what'd be in
your file anyway), but from other sources you can experiment with hashrefs or
arrayrefs and see which is faster for your uses.
dynamic messages apply to only message information. use dynamic_header_data for
dynamic pieces in headers.
Note that the dynamic message creation will be performed in an arbitrary order.
So don't expect to have one piece of the dynamic message populate into your
message before another one.
There is one special key for dynamic_message_data, "_default".
$dynamic->dynamic_message_data(
{
'<agegroup>' => {
'over70' => 'napping',
'40-50' => 'amassing wealth',
'20-40' => 'working',
'under20' => 'playing',
'_default' => 'You have not specified an age group'
},
'<animallover>' => {
'hates_animals' => "I see you hate animals.",
"likes_animals" => "I see you like animals.",
"loves_animals" => "I see you love animals.",
"_default" => "I don't know how you feel about animals"
},
'<personalized>' => {
'yes' => 'Hi there, <name>',
'no' => 'Hi there',
}
}
);
It should be fairly obvious - if that key is not specified, then the _default
value is used. Using our earlier example, with the following list:
foo@bar.com::Mr. Foo::23::<agegroup>=20-40
And the same message of:
<personalized>. Judging by your age, which is <age>, you should enjoy <agegroup>.
Oh, and <animallover>
The messages sent out would be, respectively:
. Judging by your age, which is 23, you should enjoy working.
Oh, and I don't know how you feel about animals.
Note that since <agegroup> was specified, we used that value. Since
<animallover> was not specified, the default was used, and since <personalized>
was not specified and has no default, it was simply wiped out.
dynamic_message_delimiter
If you're reading in from a file, you can't have arrayrefs, hashrefs, whatever.
They don't store nicely in text. So your data will probably be a delimited
string. In that case, you need to know the delimiter. Set it with
dynamic_message_delimiter. Note that your dynamic message data is just an entry
in your merge data. We'll assume a merge_delimiter of '::' and a
dynamic_message_value_delimiter of '=' for these examples
->merge_keys([qw(BULK_EMAIL <name> BULK_DYNAMIC_MESSAGE)]);
#in your list
jim@jimandkoka.com::Jim::agegroup=20-40;animallover=yes
#then
$dynamic->dynamic_message_delimiter(";");
#in your list
jim@jimandkoka.com::Jim::agegroup=20-40&animallover=yes
#then
$dynamic->dynamic_message_delimiter('&');
#in your list
jim@jimandkoka.com::Jim::agegroup=20-40,,animallover=yes
#then
$dynamic->dynamic_message_delimiter(',,');
Just be sure that your delimiting string occurs *only* as the delimiter and is
never embedded in your data. No escaping of a delimiter is possible.
dynamic_message_value_delimiter
If you're reading in from a file, you can't have arrayrefs, hashrefs, whatever.
They don't store nicely in text. So your data will probably be a delimited
string. In that case, you need to know the delimiter. Set it with
dynamic_message_delimiter. Note that your dynamic message data is just an entry
in your merge data. We'll assume a merge_delimiter of '::' and a
dynamic_message_delimiter of ';' for these examples
->merge_keys([qw(BULK_EMAIL <name> BULK_DYNAMIC_MESSAGE)]);
#in your list
jim@jimandkoka.com::Jim::agegroup=20-40;animallover=yes
#then
$dynamic->dynamic_message_value_delimiter("=");
#in your list
jim@jimandkoka.com::Jim::agegroup:=20-40;animallover:=yes
#then
$dynamic->dynamic_message_value_delimiter(':=');
#in your list
jim@jimandkoka.com::Jim::agegroup--20-40;animallover--yes
#then
$dynamic->dynamic_message_value_delimiter('--');
Just be sure that your delimiting string occurs *only* as the delimiter and is
never embedded in your data. No escaping of a delimiter is possible.
dynamic_header_data
Mail merges are all well and good, they store unique information about a unique
email address. But sometimes you want to group together several users and send
them the same information based upon some other criteria. That's where
dynamic_message_data comes in handy. dynamic_header_data is virtually identical
to dynamic_message_data in terms of behavior, but it operates on the message
header instead of the message instelf.
This is probably easiest explained via examples. dynamic_header_data is a
hashref of hashrefs, such as this:
$dynamic->dynamic_header_data(
{
'Subject' => {
'polite' => "Hello, sir",
"impolite" => "Hello",
"rude" => "Hey, jerk-off"
},
'Reply-To' => {
'useful' => 'return@myaddress.com',
'semiuseful' => 'filteredreturn@myaddress.com',
'useless' => 'nowhere@noemail.com'
},
'X-Type' => {
'premium' => "All Services are available",
"gold" => "Most servies are available",
"none" => "No services are available"
}
}
);
Now then, your merge keys could be defined as such:
->merge_keys([qw(BULK_EMAIL <name> <age> BULK_DYNAMIC_MESSAGE BULK_DYNAMIC_HEADERS)]);
Your list would be:
foo@bar.com::Mr. Foo::23::agegroup=20-40;animallover=hates_animals;personalized=yes::Subject=polite;Reply-To:useful;X-Type:gold
me@there.com::Bob Hope::78::agegroup=over70;animallover=likes_animals;personalized=no::Subject=rude;Reply-To:useful;X-Type:premium
john@junior.com::John Jr.::14::agegroup=under20;animallover=likes_animals;personalized=yes::Subject=impolite;Reply-To:useless;X-Type:none
The messages sent out would have the following headers, respectively:
Subject : Hello, sir
Reply-To: return@myaddress.com
X-Type : Most services are available
Subject : Hey, jerk-off
Reply-To: return@myaddress.com
X-Type : All Services are available
Subject : Hello
Reply-To: nowhere@noemail.com
X-Type : No services are available
See? easy as pie. Your dynamic headers should be specified in your merge_keys
as BULK_DYNAMIC_HEADERS, and should be a delimited string (in this case).
Subject=polite;Reply-To=useful;X-Type=gold
You can specify what delimiters you'd like to use. In this case, your
dynamic_header_delimiter is ';', and your dynamic_header_value_delimiter is
'='.
More clearly, this information translates to the following:
Subject => polite
Reply-To => useful
X-Type => gold
Note that unlike dynamic_message_data, the key in this case is not used to
substitute out a string in your headers (or message), the key is used to name
the header that is appended on the message.
Dynamic header creation is done before mail merging, so you are more than
welcome to put mail merge tokens inside your dynamic headers.
Don't use the same tokens for mailmerges and dynamic headers, since the system
may get confused.
Alternatively, instead of a delimited string, you may pass in an arrayref of
strings:
[qw(Subject=polite Reply-To=useful X-Type:gold)]
or an arrayref of arrayrefs:
[[qw(Subject polite)], [qw(Reply-To useful)], [qw(X-Type gold)]]
or a hashref:
{
Subject => polite
Reply-To => useful
X-Type => gold
}
Passing in a hashtable is the fastest in terms of internal processing, but
there may be additional work on your end to generate the hash. When reading
from a file, you should always use delimited strings (since that's what'd be in
your file anyway), but from other sources you can experiment with hashrefs or
arrayrefs and see which is faster for your uses.
dynamic headers apply to only header information. use dynamic_message_data for
dynamic pieces in messages.
Note that the dynamic header creation will be performed in an arbitrary order.
So don't expect to have one piece of the dynamic header populate into your
message before another one.
There is one special key for dynamic_header_data, "_default".
$dynamic->dynamic_message_data(
{
'Subject' => {
'polite' => "Hello, sir",
"impolite" => "Hello",
"rude" => "Hey, jerk-off",
'_default' => "Default subject",
},
'Reply-To' => {
'useful' => 'return@myaddress.com',
'semiuseful' => 'filteredreturn@myaddress.com',
'useless' => 'nowhere@noemail.com',
'_default" => 'reply@to.com'
},
'X-Type' => {
'premium' => "All Services are available",
"gold" => "Most servies are available",
"none" => "No services are available"
}
}
);
Behavior is similar to that of _default in dynamic_message_data. If a header is
specified, it is used. If no value is specified, it will attempt to use the
_default value. But, in this case, if there is no value passed and no default,
then the header just won't be set. Unless it is one of the speciality headers,
such as From. In that case, it will attempt a specific dynamic_message_data
value for From, then the "_default" value in dynamic_message_data for from, and
then finally the ->From value itself.
If there's a header specified in ->dynamic_header_data, it will be preferred to
use over one set via ->header.
i.e., the order that a header will be checked is:
1) Is there a specific header key for the header? (Subject => polite)
2) Is there a default header key for the header? (Subject => _default)
3) Is this a specialty header (i.e., ->From), and is that set? ($bulk->From())
4) Is there a generic, non-dynamic header set? (->header('Foo'))
Headers will not be set more than once, no matter how many places you specify
them.
dynamic_header_delimiter
If you're reading in from a file, you can't have arrayrefs, hashrefs, whatever.
They don't store nicely in text. So your data will probably be a delimited
string. In that case, you need to know the delimiter. Set it with
dynamic_header_delimiter. Note that your dynamic header data is just an entry
in your merge data. We'll assume a merge_delimiter of '::' and a
dynamic_header_value_delimiter of '=' for these examples
->merge_keys([qw(BULK_EMAIL <name> BULK_DYNAMIC_HEADERS)]);
#in your list
jim@jimandkoka.com::Jim::Subject=polite;Reply-To=useful
#then
$dynamic->dynamic_message_delimiter(";");
#in your list
jim@jimandkoka.com::Jim::Subject=polite&Reply-To=useful
#then
$dynamic->dynamic_message_delimiter('&');
#in your list
jim@jimandkoka.com::Jim::Subject=polite,,Reply-To=useful
#then
$dynamic->dynamic_message_delimiter(',,');
Just be sure that your delimiting string occurs *only* as the delimiter and is
never embedded in your data. No escaping of a delimiter is possible.
dynamic_header_value_delimiter
If you're reading in from a file, you can't have arrayrefs, hashrefs, whatever.
They don't store nicely in text. So your data will probably be a delimited
string. In that case, you need to know the delimiter. Set it with
dynamic_header_delimiter. Note that your dynamic header data is just an entry
in your merge data. We'll assume a merge_delimiter of '::' and a
dynamic_header_delimiter of ';' for these examples
->merge_keys([qw(BULK_EMAIL <name> BULK_DYNAMIC_HEADERS)]);
#in your list
jim@jimandkoka.com::Jim::Subject=polite;Reply-To=useful
#then
$dynamic->dynamic_message_value_delimiter("=");
#in your list
jim@jimandkoka.com::Jim::Subject:=polite;Reply-To:=useful
#then
$dynamic->dynamic_message_value_delimiter(':=');
#in your list
jim@jimandkoka.com::Jim::Subject--polite;Reply-To--useful
#then
$dynamic->dynamic_message_value_delimiter('--');
Just be sure that your delimiting string occurs *only* as the delimiter and is
never embedded in your data. No escaping of a delimiter is possible.
quotemeta boolean flag. 1/0
While mailmerging, you can specify keys that would contain regex meta data.
For example:
->merge_keys [qw(*name* BULK_EMAIL)]
Would generate an error, because the * character has special meaning to a
regex. With quotemeta turned on, you can use that as a token because it will be
quoted when used in the regex.
It is highly recommended that you leave quotemeta set to 1. Set it to 0 only if
you really know what you're doing.
use_envelope
In this subclass, use_envelope is a method that will always return 0.
For Dynamic messages, it's impossible to use the envelope. Sorry, gang, if you
want to use mail merges, then you can't use the added speed that the envelope
provides you with.
And it only makes sense, because envelope sending sends the exact same message
to multiple people. If you're doing a mail merge, then you're customizing each
message, so it wouldn't make sense to send that thing to multiple people.
For raw speed, use Mail::Bulkmail and use_envelope => 1. For mail merges, use
this.
METHODS
extractEmail
extractEmail is an overridden method from Mail::Bulkmail. Most of the time when
you're in Mail::Bulkmail::Dynamic, the data structure that's passed around
internally is a hashref, and the email address is at the key BULK_EMAIL.
This extracts that key and returns it. Again, this method is used internally
and is not something you need to worry about.
This method is known to be able to return:
MBD001 - no BULK_EMAIL defined
extractSender
extractSender is an overridden method from Mail::Bulkmail. Most of the time
when you're in Mail::Bulkmail::Dynamic, the data structure that's passed around
internally is a hashref, and the sender is at the key BULK_SENDER.
This extracts that key and returns it. Again, this method is used internally
and is not something you need to worry about.
This method is known to be able to return:
MBD015 - no BULK_SENDER defined
extractReplyTo
extractReplyTo is an overridden method from Mail::Bulkmail. Most of the time
when you're in Mail::Bulkmail::Dynamic, the data structure that's passed around
internally is a hashref, and the email address is at the key BULK_REPLYTO.
This extracts that key and returns it. Again, this method is used internally
and is not something you need to worry about.
This method is known to be able to return:
MBD016 - no BULK_REPLYTO defined
buildHeaders
Another overridden method from Mail::Bulkmail. This one constructs headers and
also includes any dynamic headers, if they have been specified in
BULK_DYNAMIC_HEADERS.
And, finally, it will do a mail merge on all headers (first global, then
individual).
Still called internally and still something you don't need to worry about.
This ->buildHeaders cannot accept the optional second headers_hash parameter
This method is known to be able to return:
MBD013 - cannot bulkmail w/o From
MBD014 - cannot bulkmail w/o To
buildMessage
Another overridden method from Mail::Bulkmail. This one constructs the message
and also includes any dynamic message content, if it has been specified in
BULK_DYNAMIC_MESSAGE.
And, finally, it will do a mail merge on the message (first global, then
individual).
Still called internally and still something you don't need to worry about.
This method is known to be able to return:
MBD012 - cannot build message w/o message
preprocess Overridden from Mail::Bulkmail, preprocesses the data returned from
getNextLine($bulk->LIST) and makes sure that Mail::Bulkmail::Dynamic knows how
to work with it. Constructs the internal data structures to handle mail merges,
dynamic messages, and dynamic headers, for any of those items that are in use.
Still called internally and still not something you need to worry about.
buildMessageHash
Given a delimited string, arrayref, or hashref, formats it according to the
information contained in merge_keys and returns it.
Called internally, and not something you should worry about.
This method is known to be able to return:
MBD002 - no merge_delimiter
MBD003 - different number of keys and values
MBD004 - cannot bulid merge hash
buildDynamicMessageHash
Given a delimited string, arrayref, or hashref, formats it according to the
information contained in dynamic_message_data and returns it.
Called internally, and not something you should worry about.
This method is known to be able to return:
MBD005 - cannot split w/o dynamic_message_delimiter
MBD006 - cannot split w/o dynamic_message_value_delimiter
MBD007 - invalid dynamic message key
MBD008 - cannot build dynamic message hash
buildDynamicHeaderHash
Given a delimited string, arrayref, or hashref, formats it according to the
information contained in dynamic_header_data and returns it.
Called internally, and not something you should worry about.
This method is known to be able to return:
MBD008 - cannot split w/o dynamic_header_delimiter
MBD009 - cannot split w/o dynamic_header_value_delimiter
MBD010 - invalid dynamic header key
MBD011 - cannot build dynamic header hash
convert_to_scalar
convert_to_scalar is still used exclusively internally here, and you still
don't need to worry about it. The difference is that this time, our data
passed in is not just a simple email address - it's a hash. If log_all_data is
set to true, then you get back the data in the form that you had originally
passed it, arrayref, hashref, or delimited string.
Alternatively, the user can decide to just log the email address, if the
dynamic and merge information are not important.
