**Auto-populate** uses the open [Domain Connect](https://www.domainconnect.org/) standard. Reloop opens your DNS provider, you approve a template, and the provider writes SPF, DKIM, DMARC, MX, and tracking records for you.

Which hosts can do this **changes over time**. Reloop does not rely on a fixed allowlist in the docs — it checks live whether your domain’s DNS host supports Reloop’s Domain Connect template (`reloop.sh` / `email-setup` in the [Domain Connect Templates](https://github.com/Domain-Connect/Templates) registry).

## When you see the button

On the domain page (and during onboarding DNS step):

- **Auto populate** → your host can apply Reloop’s template; use this flow
- **Open DNS settings** (or no Auto populate) → use [manual setup](/docs/guides/connect-domain/manual-setup)

Trust the dashboard for your domain. A host that supports Domain Connect in general may still lack Reloop’s template until they onboard it.

## How the flow works

<Steps>
  <Step title="Click Auto populate">
    Reloop runs Domain Connect **discovery** against your domain (`_domainconnect` DNS + provider API) and confirms the Reloop template is available.
  </Step>
  <Step title="Approve at your provider">
    A new tab opens on your DNS host. Sign in if needed, review the records, and confirm.
  </Step>
  <Step title="Return to Reloop">
    After success you are redirected back (or you can return manually). Click **Verify** if status is still pending.
  </Step>
</Steps>

Reloop re-checks live discovery when you click Auto populate. If the provider dropped the template or discovery fails, you get an error toast and should continue manually.

## What gets applied

The Reloop Domain Connect template typically applies:

- DKIM TXT on `reloop._domainkey`
- SPF via SPFM / merge (`include:reloop.sh`)
- DMARC on `_dmarc`
- MX for sending/receiving as defined in the template
- Tracking CNAME `link` → `link.reloop.sh`

Exact groups can depend on template version; the consent screen lists what will change.

## If Auto-populate fails

See [Auto-populate failed](/docs/guides/connect-domain/troubleshoot/auto-populate-failed) for:

- Popup blocked
- User cancelled consent
- Template not found at provider
- Domain Connect not supported on that zone

You can always fall back to [manual setup](/docs/guides/connect-domain/manual-setup) using the same dashboard records.

## Security notes

- Only approve the flow while logged into **your** DNS account for that domain.
- Reloop signs Domain Connect apply URLs; do not reuse apply links from untrusted sources.
- After you approve, check the records in your DNS panel, then click **Verify** in Reloop.
