Kingmailer is a cloud-based SMTP provider that acts as an email delivery engine, allowing you to send email without the cost and complexity of maintaining your own email servers. Kingmailer manages the technical details of email delivery, like infrastructure scaling, ISP outreach, reputation monitoring, and real-time analytics.
Kingmailer is designed to help you send marketing email. It allows you to upload and manage recipient lists, build or upload your own HTML email templates, and then schedule and send your email campaigns through Kingmailer. This option works well for bulk, newsletter-type sends.
Every time you make a request to send one message to one recipient, it is counted by Kingmailer as a message sent, regardless of the message being deferred or sent to spam.
When you’re ready to sign up, select the plan that suits your needs based on your monthly email volume. We accept credit cards and charge on the first of every month. There are no contracts—each plan is month-to-month—and you can cancel at any time. If you want to do some testing before signing up for a paid plan, you can integrate with Kingmailer and send up to 240 emails per day, every day, with your free account.
You can send up to 7,200 emails per month, 20 emails per hour, forever free. While this not be much, it is still a perfect way to test our platform. If you wish to remove this limit, you can upgrade.
