**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.

## When you see the button

Reloop shows **Auto populate** when nameserver detection matches a host where Reloop’s Domain Connect template is known to work today:

- [Cloudflare](/docs/guides/connect-domain/providers/cloudflare)
- [Vercel](/docs/guides/connect-domain/providers/vercel)
- [Domain Chief](/docs/guides/connect-domain/providers/domain-chief)
- [NameSilo](/docs/guides/connect-domain/providers/namesilo)

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

- **Auto populate** → use this flow
- **Open DNS settings** (or no Auto populate) → use [manual setup](/docs/guides/connect-domain/manual-setup)

When you click **Auto populate**, Reloop also runs live Domain Connect discovery as a safety check (`_domainconnect` DNS + provider API) to confirm the Reloop template (`reloop.sh` / `email-setup`) is still available. A host that supports Domain Connect in general may still fail that check if Reloop’s template is not onboarded there.

Trust the dashboard for your domain: if the button is missing, use manual setup even if the provider advertises Domain Connect elsewhere.

## Defaults before you approve

New domains start with **Email Receiving** and **click/open tracking** on. Auto-populate therefore typically includes inbound MX (`inbound.reloop.sh`) and the tracking CNAME unless you turn those off first.

<Warning>
If this hostname already uses Google Workspace, Microsoft 365, or another inbox, turn **Email Receiving** off on the Reloop domain page before Auto-populate — or use a [separate subdomain](/docs/guides/connect-domain/what-is-a-domain) for Reloop. See [Sending vs receiving](/docs/guides/connect-domain/sending-vs-receiving).
</Warning>

## How the flow works

<Steps>
  <Step title="Click Auto populate">
    Reloop runs Domain Connect discovery and builds a signed apply URL when 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 & finish** on the setup page, or **Verify Domain** on the domain detail page, if status is still pending.
  </Step>
</Steps>

If discovery fails or the provider dropped the template, you get an error toast and should continue manually.

## What gets applied

The Reloop Domain Connect template typically applies groups based on your domain toggles:

- DKIM TXT on `reloop._domainkey`
- SPF via SPFM / merge (`include:reloop.sh`)
- DMARC on `_dmarc` (required for verification when Email Sending is on)
- **Sending MX** → `reloop.sh` when Email Sending is on
- **Receiving MX** → `inbound.reloop.sh` when Email Receiving is on (default for new domains)
- Tracking CNAME → `link.reloop.sh` when tracking is on (host is usually `link` on apex, or `link.<subdomain>` when the Reloop domain is a subdomain)

Exact groups depend on your toggles and template version; the consent screen lists what will change. Always confirm hosts and values in the Reloop dashboard.

## 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 Domain** (or **Verify & finish**) in Reloop.
