Set up your email domain

To send emails to your merchants from your own domain, you authenticate a sending subdomain with three DNS records. mcamgr never touches your inbound mail (your MX records) - this only affects sending.

Why a subdomain?

We recommend a dedicated sending subdomain such as send.yourcompany.com. This keeps your main domain's reputation and inbound email untouched, and keeps authentication clean.

The three records

| Record | Purpose | | --- | --- | | SPF / Return-Path | Authorizes our mail servers to send for your subdomain and aligns bounce handling. | | DKIM | Cryptographically signs your mail so receivers can verify it wasn't forged. | | DMARC | Tells receivers what to do with mail that fails the checks, and where to send reports. |

How to add them

1. In mcamgr, open Settings → Email domains and enter your sending domain.
2. We'll show you the exact records to add. If your DNS provider is supported, you can click Configure automatically and approve the change - no copy and paste needed.
3. Otherwise, copy each record into your DNS provider's dashboard.
4. Click Verify. Propagation is usually minutes; once verified, the domain goes live for sending.

DMARC policy

Start with a monitoring policy and tighten it over time:

v=DMARC1; p=none; rua=mailto:dmarc@yourcompany.com

Once you've confirmed your mail passes, move p=none to p=quarantine and eventually p=reject for the strongest protection.
