Sendinblue made email marketing easier with a lot of features and functions.
I tried to add a second email to my account and it went straight into spam. Then the confirmation link inside didn't work (404). Then whitelisting my local domain didn't work, so now I'm stuck. Therefore, I have no interest in going any further as I can't be bothered waiting around for them to fix things.
SendinBlue is cost effective and easy to use for email marketing
