Why mail sending speed very slow?

Hello
Why mail sending speed very slow? Only 3000 emails were sent in one day.

You can follow https://kb.mailwizz.com/articles/debug-send-campaigns-command/ and see what is going on.
In one of our tests, we achieved 700 emails/second, so i really doubt the issue is on mailwizz's side.

@Jam nick - As the error says, mailwizz cannot find a valid server to send campaign. Please check this article: https://kb.mailwizz.com/articles/ca...borting-until-a-delivery-server-is-available/
