Buy SMTP with Bitcoin

We accept Bitcoin. Buy your SMTP Server and pay with Bitcoin. Try our SMTP service for free. Start sending and receiving emails with your free SMTP username and password. Upgrade and pay with Bitcoin when you are ready.

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

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