 * Hi,
 * I would need to bulk email over 100, 000 people in one go.
 * I use Amazon SES to deliver the emails.
 * My server has multiple cores.
 * Performance is a big issue, need to have all of these emails processed for delivery
   within ~30mins.
 * Does this plugin have multi-threading features, so, that more emails are processed
   simultaneously to be passed onto ASES for delivery?
 * Thanks,

 * Actually not since PHP is not mutithreading.

 * Thanks for the swift response.
 * There’s another software that makes use of `curl_multi_exec` function in PHP.

 * Have you considered this option?
 * I would really love to use this plugin, but, multi-threading (or non-blocking)
   is a must.

 * Yes, considered, tested a got a lot of problems. That could work on dedicated
   server, usually on shared hosting creates a lot of problem (probably due to the
   number of thread launched).
 * We could try to add this option in future versions but limit it only to server
   which support it… and we need to understand when it’s the case to enable it (
   otherwise everyone will try to enable it and then reporting tons of issues).

 * Ah great, we run VPS, so, we have a dedicated OS and PHP instance. Besides, we
   have no issues with Sendy which uses the same method.
 * I’m not aware of any Shared hosting that allows this much amount of multi-threading,
   it has to be VPS/Dedicated.
 * Can you advise me on how to enable this in your plugin please? I want to give
   it a try on my VPS.
 * Thanks,

 * Hi,
 * Any updates on this?
 * Would it be possible to enable this option in the plugin (as I have WordPress
   on a VPS)?

 * Hi, multithread can be implemented in many ways, we’re now experimenting with
   curl multi which should be the best way but it is only applicable to external
   integrations which uses API calls to send emails.
 * If that work we can try with the native delivery using the mail() function of
   PHP but that means expose an sending API directly by the blog.
