Stop having to worry about public open relays, complicated SMTP testing workflows, or insecure email hacks.

Developers can send and receive private email over SMTP, HTTP/JSON, WebHooks, and Web Sockets.

Cost Effective

Much Lower TCO vs Self-Hosted SMTP

Developers can be up-and-running in minutes or hours, instead of days or weeks, due to zero-config SMTP setup solutions. Or add a few predetermined DKIM and SPF records to use your own domain.

All-Inclusive billing

Know your bill ahead of time. No surprise usage overages.

Almost a Decade of Experience

Mailsac has specialized in disposable email for almost 10 years. Leverage our optimizations and learnings, instead of rolling-your-own.
