Amazon SES configuration send email immediately

I connected to Amazon SES - API for sending emails from Mautic. However, I noticed a lot of slowness in sending emails from both campaigns and masses. I have the ability to send 150 emails / second with Amazon SES, but I can’t fully exploit this power.

My Amazon SES is also used for sending emails with other mechanisms besides Mautic.

Seeing the settings on the forum and on the web I noticed that many put “send immediately” instead of queue as send settings even if reading from the Mautic documentation it is recommended to use the queue (which I currently do).

I’m afraid that this is what slows down the sending, can you confirm me?

I also have other questions for you:

  1. Could sending immediate email from Mautic to Amazon SES cause problems sending emails from other systems? I am afraid of exceeding the limit that I have available with Amazon SES and thus ruining my reputation
  2. Could sending direct emails slow down the system? Reading from the documentation on the site it seems to be recommended to use the queue, but seeing later tutorials on how to connect to Amazon SES they all use “send immediately”

Hello David,

The 150/s is a limitation set by Amazon SES, but you need a pretty strong server to achieve it.

Queue processing will speed up the overall sending, because queue formation happens before.
So you will send in 2 steps (if you queue processing is set up right.)

Yes, that can happen. Don’t send too fast.

Don’t listen to those tutorials. Queuing is great. People Don’t understand how it works, and they are afraid to use it. This is why they recommend not to use it. This forum has multiple solutions about queue processing.

Thanks for the reply. I’m sure it will be the solution to my problems. I will let you know here if the operation was successful!
