@twisted1919 , you are yet to treat my ticket since may 29th bruh... My sending is still very slow... Same settings and tweak I used in sending 10k subscribers in 1 minutes now it take over 24hours to send to 400k leads instead of less than 3 hours.
Improving the delivery speed, or things in this category is not covered by support in any way. Actually, beside basic support questions nothing else is included in support. Anything that requires me to do any type of custom work is not included in support.
I just do it because i like helping people out. But i can only do it when i have extra time and nowadays really i don't have, thus the delay in my reply to your conversation.
There are plenty article covering all possible reasons for slow sending, best is to debug the send campaigns command and see where mailwizz spends the most time. My advice is to hire someone to help you with this kind of things as they are not our responsability in any way.
That being said, if i get a chance, i'll have a look, but as i said, nowadays we're super busy.
Also, as
@Kieron Garvey says, please do not spam other people threads. i will remove your post now, but please keep this in mind.
@Kieron Garvey - Maybe it has something to do with permissions. Did you by any chance uploaded the update files as the root user ?
