Lumi does not create mailboxes. First choose an email provider, add the domain there, and copy the DNS records it gives you.

What to add in the bot

Open My domains → domain → DNS settings.
1

Add MX records

For the root domain, tap Skip. Send the priority and server together, for example 10 mx1.provider.com. Add each MX separately.
2

Add the verification record

The email provider may give you TXT or CNAME. Copy the name and value exactly. CNAME verification records often need DNS only.
3

Add SPF and DKIM

These are TXT records. Always use the values shown by your email provider.
4

Add DMARC

This is usually a TXT record named _dmarc. Follow the provider’s recommended initial policy and reporting address.
5

Verify at the provider

Return to the email dashboard and run its domain verification after creating the records.

Common mistakes

  • Two SPF records exist on the root domain. Merge them into one record.
  • Extra quotation marks were added to a TXT value.
  • An MX value was entered without its priority.
  • An A or CNAME record for mail is still proxied. Email traffic needs DNS only.
  • Records were added in Lumi while the domain uses external nameservers. Update DNS at the current provider instead.
MX, SPF, DKIM, and DMARC values are provider-specific. Do not copy values from unrelated examples.
If the email provider cannot find the records, check them with DNSChecker and follow the troubleshooting checklist.
