Sender Domains

Use these tools to prepare and verify the domains used for sending emails. A correctly configured sender domain helps establish trust with receiving email providers and supports authenticated delivery.

For example, you can register a domain, inspect the required DNS settings, check its verification status, or trigger a new DNS check. The supported setup and verification actions may expand as sending requirements evolve.
