# Strato

> Verify your domain on Strato with Resend.

## Add Domain to Resend

First, log in to your [Resend Account](https://resend.com/login) and [add a domain](https://resend.com/domains).

![Domain Details](https://mintcdn.com/resend/JHWt09hsc7E33HK2/images/dashboard-domains-resend-add-domain.png?fit=max\&auto=format\&n=JHWt09hsc7E33HK2\&q=85\&s=418dd93c2f2ead0b0d83d1b7c2fb0970)

> [!TIP]
>
> It is [best practice to use a
> subdomain](/docs/knowledge-base/is-it-better-to-send-emails-from-a-subdomain-or-the-root-domain)
> (updates.example.com) instead of the root domain (example.com). Using a
> subdomain allows for proper reputation segmentation based on topics or purpose
> (e.g. marketing) and is especially important if receiving emails with Resend.

## Log in to Strato

Log in to your [Strato account](https://www.strato.es/apps/CustomerService):

1. In the left-hand navigation, go to Domains > Manage Domain.

![Domain Details](https://mintcdn.com/resend/JHWt09hsc7E33HK2/images/dashboard-domains-strato-domain-manager.png?fit=max\&auto=format\&n=JHWt09hsc7E33HK2\&q=85\&s=684004473fd6679100907921ce2767df)

## Add MX SPF Record

1. On the domain page, click on the gear icon to redirect to Settings.
2. Create a new subdomain named `send`.
3. Navigate to the subdomain settings.
4. Go to the `DNS` tab, you'll see a list of DNS records you can update. Click on `manage` MX record.
5. Select own mail server.
6. Copy MX value from Resend into `Server` field.
7. Use the default priority `Low`.
8. Save settings.

> [!NOTE]
>
> By default, Strato domains use Strato mail server which uses `mail` as their
> send path. You will need to bypass this default behavior by creating a
> subdomain and setting the MX record there.

2. Manage TXT and CNAME records.
3. On the bottom, click `Create another record`.

5. Add `send` for the `name` record.
6. For `value` input `v=spf1 include:amazonses.com ~all`.
7. Save settings.

> [!NOTE]
>

> `v=DMARC1;p=reject;`.

> [!NOTE]

> `resend._domainkey.subdomain` if you're using a subdomain).

> [!NOTE]

> Copy DKIM value using the small copy icon in Resend. DKIM records are
> case-sensitive and must match up exactly.

## Receiving Emails

If you want to receive emails at your domain, toggle the "Receiving" switch on the domain details page.

![Enable Receiving Emails for a verified domain](https://mintcdn.com/resend/B7wTVm7aKL5pNT-6/images/inbound-domain-toggle.png?fit=max\&auto=format\&n=B7wTVm7aKL5pNT-6\&q=85\&s=46f6b4c142fb90e04b57861e338ed2d0)

> [!WARNING]
>
> When you enable Inbound on a domain, Resend receives *all emails* sent to that
> specific domain depending on the priority of the MX record. For this reason,
> we strongly recommend verifying a subdomain (`subdomain.example.com`) instead
> of the root domain (`example.com`). Learn more about [avoiding conflicts with
> your existing MX
> records](/docs/knowledge-base/how-do-i-avoid-conflicting-with-my-mx-records).

> [!NOTE]
>
> Always copy the MX record value shown on your domain's page in Resend. The
> values in this guide are examples. Depending on your domain you will see
> `receive.forge.rmta.net`, a regional variant such as
> `receive-euw1.forge.rmta.net`, or `inbound-smtp.<region>.amazonaws.com`.

1. Create a new subdomain named `inbound` (or whatever your subdomain is).
2. Navigate to the subdomain settings.
3. Go to the `DNS` tab and click on `manage` MX record.
4. Select own mail server.
5. Copy MX value from Resend into `Server` field.
6. Use the default priority `Low`.
7. Save settings.

Below is a mapping of the record fields from Resend to Strato:

| Strato | Resend | Example Value |
| - | - | - |
| Type | Type | `MX Record` |
| Name | Name | `inbound` |
| Mail server | Content | `inbound-smtp.us-east-1.amazonaws.com.` |
| Priority | Priority | `Low` |

After verifying your domain, create a webhook to process incoming emails. For help setting up a webhook, how to access email data and attachments, forward emails, and more, see [our guide on receiving emails with Resend](/docs/dashboard/receiving/introduction).

## Complete Verification

Now click [Verify DNS Records](https://resend.com/domains) on your Domain in Resend. It may take a few hours to complete the verification process (often much faster).

## Troubleshooting

If your domain is not successfully verified, these are some common troubleshooting methods.

> **Resend shows my domain verification failed.**
>
> Review the records you added to Strato to rule out copy and paste errors.

> **It has been longer than 72 hours and my domain is still Pending.**
>
> [Review our guide on a domain not verifying](/docs/knowledge-base/what-if-my-domain-is-not-verifying).
