I need a few suggestions..

[danix]

Hello everybody,
I'm building a subscription plugin, as of now it's capable of sending an email every time a new blog post is added, but that slows down the publishing of new posts since WP has to wait for my plugin to send an email to every subscriber.
I thought I could build a queue and work on it using wp_cron.. do you think this would be feasible??
Can you suggest some way to build it?? I don't need the actual code, just a few hints on how to implement the whole queue system..

I designed this plugin to have an entry in the options table with an array filled with those email address that verified their subscription, something like this:

 Array
(
    [0] => "some.email@example.com",
    [1] => "some.other@example.com",
    [2] => "someone@example.com"
); 
  

but in its actual state, my code iterates through this array and sends an email when the new_to_publish action is fired.

What I would like to do is make the actual sending of the email with a wp_cron job, and optionally split the queue in small sub queues so that the overhead on the webserver is not too heavy..


Thanks a lot for your help.. :)

Are you using wp_mail($to, $subject, $message, $headers, $attachments)
to send your email? That function uses phpmailer class. It allow to
use BCC. You need to add the BCC to the $header parameter.

The string for BCC should be : "Bcc:
some.email@example.com;some.other@example.com;someone@example.com" .
PHP_EOL;

Use your own email adress for $to.

Hi nbtetreault, thanks for replying..

Yes, I'm using wp_mail() but no, I can't use this approach since I'm generating custom content for each email address (an unsubscription link), and so I can't simply add every address as bcc but I need to fetch them from the db one by one..

Do you have any other idea??

Thanks again..

I know next-to-nothing about email newsletter functionality from WordPress core, but my initial thought was: why not provide an interface to an existing email-subscription service, rather than try to reinvent the wheel within WordPress?

@chipbennett:
I didn't think about that.. I'll have a look at how to integrate some services like mailchimp.. I hope this doesn't get too hard to do..

Thanks a lot!!
