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.


Kingmailer provides everything you’ll need for sending, receiving and routing (forwarding) your emails.
