Add a new domain to Smailor

Use your own domain (for example support.example.com or mail.yourbrand.com) to send and receive mail through Smailor. Everything you must publish is surfaced in Settings → Domains once you start setup.

1. Add the domain

Go to Settings → Domains → Add domain.
Enter the exact hostname customers will see (apex or subdomain).
Complete ownership verification using the TXT (or equivalent) record the dashboard shows.

2. DNS records

Add the records Smailor lists for your domain — typically:

Purpose	What you usually add
Ownership	One-time TXT (or DNS provider flow)
Inbound mail	MX records toward the inbound path we specify
Outbound auth	SPF (TXT), DKIM (TXT/CNAME depending on dashboard), optional bounce helpers
Policy	DMARC (TXT on `_dmarc`) — start with `p=none` if you are unsure

Values are not generic: copy them from the Domains and Deliverability screens so they match your account and our current sending configuration.

Tips

Turn off HTTP/proxy “orange cloud” (or equivalent) on records that must be raw DNS for mail, if your provider requires it.
One SPF TXT per sending hostname — merge includes instead of creating multiple SPF TXTs on the same name.

3. Verify

Save DNS at your registrar or DNS host.
In Smailor, open the domain → Deliverability → Verify DNS.
Wait for propagation if checks stay red; retry after a few hours.

4. Send and receive

Outbound: once the domain is verified and DNS checks pass, you can use addresses on that domain in the product and via the REST API within your plan limits.
Inbound: replies and messages to your addresses are handled by Smailor’s mail pipeline as long as MX matches what we instruct you to publish.

5. Checklist before going live

Ownership verified
MX for inbound copied from Smailor
SPF reflects dashboard guidance
DKIM shows Verified
DMARC present (recommended before strict policies)
