Title: Mail queue plugin Last modified: August 22, 2016 --- # Mail queue plugin * [zimbo000](https://wordpress.org/support/users/zimbo000/) * (@zimbo000) * [11 years, 2 months ago](https://wordpress.org/support/topic/mail-queue-plugin/) * There have been a couple of questions about this recently but I too have just hit the same problem. My ISP imposes a send limit of 25 recipients per email but I have 200+ subscribers, and the first attempt to send a digest email to them all failed. * The ISP will not increase its per-send limit from 25. * The site uses the [WP-Mail-SMTP](https://wordpress.org/plugins/wp-mail-smtp/) plugin that reconfigures the wp_mail() function to use SMTP instead of mail(). * Such limiting must be a common problem so can you recommend a mail queueing plugin that will work with Subscribe2 to send a digest email to 200+ subscribers over a period of time (i.e. one that you know works and does conflict)? * [https://wordpress.org/plugins/subscribe2/](https://wordpress.org/plugins/subscribe2/) Viewing 6 replies - 1 through 6 (of 6 total) * [Matt Robinson](https://wordpress.org/support/users/mattyrob/) * (@mattyrob) * [11 years, 2 months ago](https://wordpress.org/support/topic/mail-queue-plugin/#post-5884276) * [@zimbo000](https://wordpress.org/support/users/zimbo000/) * I use this one (because I write it), but it’s is a paid plugin: [http://semperplugins.com/plugins/wordpress-mail-queue-wpmq/](http://semperplugins.com/plugins/wordpress-mail-queue-wpmq/) * I’ve been told that this one works too: [https://wordpress.org/plugins/mail-queues/](https://wordpress.org/plugins/mail-queues/)( But it looked a little tricker to set up when I gave it a brief look over) * Thread Starter [zimbo000](https://wordpress.org/support/users/zimbo000/) * (@zimbo000) * [11 years, 2 months ago](https://wordpress.org/support/topic/mail-queue-plugin/#post-5884471) * Does your plugin allow for multiple recipients per email – or is the queue (say, for a daily digest of 200 subscribers) processed one at a time? * e.g. for 200 emails in a queue, can I configure the plugin to send 10 x 20 recipients every xx seconds or does it have to be 1 email every yy seconds? * The ISP imposes a limit of 100 emails per hour so 200 subscribers will take 2 hours if one at a time… * [Matt Robinson](https://wordpress.org/support/users/mattyrob/) * (@mattyrob) * [11 years, 2 months ago](https://wordpress.org/support/topic/mail-queue-plugin/#post-5884474) * [@zimbo000](https://wordpress.org/support/users/zimbo000/) * WordPress Mail Queue is detected by Subscribe2 and it then sends single emails to single recipients. So, in your example above I’d recommend defining allowing 90 emails per hour so you have leeway for other emails (like comments etc) and the emails would indeed take a few hours to deliver. * Thread Starter [zimbo000](https://wordpress.org/support/users/zimbo000/) * (@zimbo000) * [11 years, 2 months ago](https://wordpress.org/support/topic/mail-queue-plugin/#post-5884505) * It appears from their documentation that Mail Queues by PBCI has its own SMTP‘ sender’ i.e. it reconfigures wp_mail() to use SMTP instead of mail(). And it does look a lot more complicated. * Does your WPMQ use SMTP to send emails or would I need to continue with the WP- Mail-SMTP plugin currently in use? If so, any potential issues come to mind? * [Matt Robinson](https://wordpress.org/support/users/mattyrob/) * (@mattyrob) * [11 years, 2 months ago](https://wordpress.org/support/topic/mail-queue-plugin/#post-5884526) * [@zimbo000](https://wordpress.org/support/users/zimbo000/) * WPMQ is just a mail queue. It can be used with SMTP plugins. I use it wit Configure SMTP for example. * Thread Starter [zimbo000](https://wordpress.org/support/users/zimbo000/) * (@zimbo000) * [11 years, 2 months ago](https://wordpress.org/support/topic/mail-queue-plugin/#post-5884537) * Thanks, I just bought WordPress Mail Queue, hopefully will be OK for tonight’s digest!
