Email Queue
The Email Queue Module optimizes bulk email delivery by batching outgoing emails, reducing server load, and ensuring efficient dispatch.
Bulk email without choking your server.
Email Queue sends the email of your site in batches from a cron job, instead of all at once. Your mail server stays responsive, you stay within the limits of your mail provider, and a failed email doesn't block the rest.

One failed email doesn't hold up the rest
When an email can't be sent, the error is stored and the email is tried again on the next run. After the last attempt it is marked as failed and skipped, so the rest of the queue keeps going.
Fix the cause and send the failed emails again with one button. Reply-to, the alt message and attachments are kept.

Queue the newsletter, not the password reset
Put {queue_email} in the emails you want to queue, like a newsletter, and the marker is removed before sending. Everything else goes out right away. Or let the queue take every email the site sends.
