I used this to connect to my site to send order and other automated emails and my fails went from around 0.02% to a massive 5%I noticed the labels showing on brevo are not accurate with reasons for failed for example my own email it showed 4 attempted, 2 send and 2 blocked at no point was the mail bocked by me.I reached out hoping for a quick reply it did not happen.I think if you are sending emails direct from the Brevo platform like most people on these reviews have done then it would be find but I would not reccomend using to connect as your main mail sender for your business. If you look at reviews on here and on other sites for Brevo and thier previous name you will see many many people have experianced the same type of issue.
