Getting started

From a bare domain to a working you@yourco.com mailbox in about ten minutes — most of which is DNS propagation.

There are three steps: add your domain, verify DNS, and create a mailbox. If you'd rather skip DNS entirely, sign up with a free @atrixmail.com address and come back to your own domain later — everything else works the same.

1. Add your domain

In the dashboard, go to Domains → Add domain and enter the domain you own, e.g. yourco.com. Atrix Mail generates a unique set of DNS records for it — including a DKIM key pair that is yours alone. Nothing about your website, registrar, or existing services changes.

  • Apex domains (yourco.com) and subdomains (mail.yourco.com) both work.
  • A domain can only be active on one Atrix Mail account at a time.
  • Plans differ only in how many domains you can add — verification is identical on all of them.

2. Verify DNS

The domain page lists four records to create at your DNS host: MX, SPF, DKIM, and DMARC. Copy each value exactly — the full reference, with a per-record explanation and registrar quirks, is on the DNS setup page.

Verification is automatic: we re-check every few minutes and flip each record from pending to verified as it propagates. Most hosts propagate in minutes; a few take up to an hour. You can also check propagation yourself:

shell
dig MX yourco.com +short
# expect: 10 mx1.mail.atrix.dev.
Mail starts flowing the moment the MX record verifies. SPF, DKIM, and DMARC affect deliverability of your outbound mail — finish all four before sending anything important.

3. Create your first mailbox

Once the domain shows verified, go to Mailboxes → New mailbox:

  1. Pick the local part — hello makes hello@yourco.com.
  2. Set a display name and a strong password (or generate one).
  3. Choose whether Iris AI features are enabled for this mailbox.

The mailbox is live immediately: open it in the webmail, or connect any IMAP client using the settings on the IMAP & SMTP page.

Next steps

  • Add aliases (support@, billing@) that deliver into an existing mailbox — Domains → Aliases.
  • Send your first programmatic email through the Sending API.
  • Subscribe to webhooks to follow deliveries, bounces, and inbound mail from your own systems.
