How does it work?
After signing up with Kingmailer you will have your own SMTP mail server, with SMTP username and password / Email API. You can use your new SMTP server and integrate with your web apps for example WordPress, Magento or iOS/Android apps.
The SMTP server is tied to your domain, make sure to add your domain first and verify its ownership by adding the SPF and DKIM records (this will be provided to you in your account).
Once you have added/verified your domain, enter the following into your SMTP configuration to start sending transactional emails:
Host: kingmailer.org Type of encryption: TLS SMTP Port: 587, 465, 25 or 2525 SMTP Authentication: Yes SMTP username and password
After following these steps, all of your transactional emails will be relayed via Kingmailer and delivered to your customers inbox.
Easy to troubleshoot emails
In your Kingmailer dashboard, you can click on each email to troubleshoot. Kingmailer logs and retains data of your emails, this is very useful when you need to troubleshoot your emails.

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 Raoul B, Adept
Costumer service has been very helpful. I can pay with Bitcoin.5/5 Jane S, IT Consultant
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 Giovanni S, Developer
Works without problems and is affordable.5/5 Frank N, Manager
