What happens when my domain is already managed by Shard Cloud?

We automatically create the SPF, DKIM, DMARC, and MX records needed for the domain. You can start creating mailboxes without manually copying records into another DNS provider.

Which records do I need to set up for an external domain?

The external-domain setup guides you through adding SPF, DKIM, DMARC, and MX records at your DNS provider, using the same email setup flow as a Shard Cloud domain.

Can my application send email through SMTP?

Yes. Use the SMTP server to send mail from your code, so product emails and team mailboxes stay under the same email service.

Can I upgrade storage for only one mailbox?

Yes. Mailboxes can be upgraded individually when one address needs more storage or higher limits, without changing the rest of your team.

How do aliases and forwarding rules work for a mailbox?

Create aliases when one mailbox needs to receive mail sent to additional addresses. Create forwarding rules when incoming mail should be sent on to another destination.

Who manages reverse DNS and mail records for a connected domain?

Shard Cloud can manage the reverse DNS and the DNS records for your email setup, so you can choose a managed setup instead of maintaining mail records yourself.
