Custom domain email
Use domains you own for product email, with optional forwarding to one verified main inbox.
Bring a domain you own
Register your domain separately. Verify ownership with TXT, then add the displayed email DNS records and activate receiving and sending. Changing MX affects every address on the domain.
One address per product, one inbox for you
Use support@, hello@ or billing@ after activation. Forwarding is optional and off by default. Verify the main inbox before enabling it, then test receiving, forwarding and website replies separately.
