Customers who are already using Kingmailer

We used Sendgrid before, but we had many issues and were looking for an alternative. We stumbled on Kingmailer and got great support setting op our account from Navin. The service works way better that Sendgrid. Where we had issues with sending emails to Hotmail and sometimes sending was blocked, we have had no problem with Kingmailer.

5/5

Costumer service has been very helpful. I can pay with Bitcoin.

5/5

Easy setup, useful dashboard, no delivery failures due to being on spam lists (unlike say, Sendgrid), API & SMTP relay. Once it’s set up, I can just forget it and be sure that it’ll work.

5/5

Works without problems and is affordable.
