Reloop can **send** mail as your domain, **receive** mail into Reloop, or both. DNS requirements differ.

## Sending (outbound)

Goal: Gmail/Outlook/others accept mail from `you@yourdomain.com` as authenticated.

Typically involves:

- **SPF** — authorize Reloop (`include:reloop.sh`)
- **DKIM** — sign messages (`reloop._domainkey`)
- **DMARC** — policy for failures
- **Tracking CNAME** — optional but used for click/open tracking (`link`)

You can keep another provider as the inbox on the same domain **if** you do not point MX at Reloop for that hostname.

## Receiving (inbound)

Goal: Mail addressed to your domain is delivered into Reloop (Agent Inbox / inbound pipelines).

Requires **MX** records pointing at Reloop’s inbound host, typically:

```
inbound.reloop.sh
```

(with the priority shown in the dashboard).

<Warning>
MX is winner-take-most for delivery. Pointing apex MX at Reloop **replaces** any existing inbox on that hostname. Use a [separate hostname](/docs/guides/connect-domain/what-is-a-domain) if you need Reloop receiving alongside another inbox.
</Warning>

## Dashboard toggles

On the domain configuration screen you may enable or disable sending/receiving features. When you change them, Reloop shows which DNS rows are required. Publish only what the dashboard marks as needed, then verify again.

## Practical recipes

| Goal | Approach |
| --- | --- |
| Transactional send only; keep existing inbox | Root or subdomain + SPF/DKIM/DMARC (+ tracking); **do not** move your current MX to Reloop |
| Full Reloop inbox + send | Subdomain or dedicated domain; MX → `inbound.reloop.sh` |
| Send from `news.acme.com`, inbox stays on `acme.com` | Add `news.acme.com` in Reloop; leave root MX alone |
