Well, I was pleased with Amazon AWS but after a technical problem on their service I stopped use it.
The problem was this: for some reason, for a few hours their service marked lots of e-mail addresses as bounced (
the email was never delivered). That causes the issue to move those email addresses to suppression list and I wasn't able to edit that list to remove the false emails.
This has the result lots of my active members to not be able to receive emails from my platform and I was received lots of service notifications that the emails was not sent.
I couldn't open a ticket on support because my account wasn't so premium.
I closed my Amazon account and I'm looking for alternative solution. Do you have one?
