Configure your domain from the dashboard.
Prerequisite: Verify Your Domain
Before sending emails, your domain must be added and verified in MailCub.

Domain verification requires setting up MX, SPF, DKIM, and DMARC DNS records at your domain provider.
Email sending will not work until domain verification is complete.
