How It Works
Up and running in three steps
No complicated setup. No DevOps degree required.
Add your domain
Enter your domain name and we generate all the DNS records you need — MX, SPF, DKIM, and DMARC. Copy them to your registrar.

Start sending
Once DNS propagates, you're live. Send and receive email, manage calendars, and monitor delivery — all from securesmtp.
