Fantastic support from Cesar and Glenn. Troubleshooting required a lot of interaction with them. But they were able to pinpoint exactly where the issue was and the problem was solved. Great to have such level of support and expertise from our provider.

I use PHPMailer to connect to MailerSend's SMTP. Today it did not work because I was using TLS v1.0 which is obsolete and no longer supported. I got a very helpful response from MailerSend service team within less than an hour, and after some brief googling changed one constant in class.smtp.php (part of PHPMailer package), and now everything works normally.

Customer service is great; when I needed an email sending platform, MailerSend made it easy for me to accomplish, when I initially thought it was going to involve a lot of knowledge base -- talking to them about my challenges and explaining my specific situation was really helpful toward getting help. I also want to thank the MailerSend Team for their support.
