# Strato

## 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](../img/site-assets/mintcdn.com/resend/JHWt09hsc7E33HK2/images/dashboard-domains-resend-add-domain-1r82328.png)

:::callout{intent="tip"}
It is [best practice to use a
subdomain](/guides/deliverability-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](../img/site-assets/mintcdn.com/resend/JHWt09hsc7E33HK2/images/dashboard-domains-strato-domain-manager-1rmmv2r.png)

## 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.

:::callout{intent="info"}
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.

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

| Strato      | Resend   | Example Value                            |
| ----------- | -------- | ---------------------------------------- |
| Type        | Type     | `MX Record`                              |
| Name        | Name     | `send`                                   |
| Mail server | Content  | `feedback-smtp.eu-west-1.amazonses.com.` |
| Priority    | Priority | `Low`                                    |

## Add TXT SPF Record

On the base domain settings:

1. Go to the `DNS` tab.
2. Manage TXT and CNAME records.
3. On the bottom, click `Create another record`.
4. Choose `TXT` type.
5. Add `send` for the `name` record.
6. For `value` input `v=spf1 include:amazonses.com ~all`.
7. Save settings.

:::callout{intent="info"}
Strato provides a standard DMARC record similar to Resend's recommended value:
`v=DMARC1;p=reject;`.

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

| Strato | Resend  | Example Value                       |
| ------ | ------- | ----------------------------------- |
| Type   | Type    | `TXT Record`                        |
| Name   | Name    | `send`                              |
| Value  | Content | `v=spf1 include:amazonses.com ~all` |

## Add TXT DKIM Records

On the same TXT and CNAME manage page:

1. Click `Create another record`.
2. Choose `TXT` type.
3. Add `resend._domainkey` for the `Name` record.
4. Copy the record value from Resend into the TXT value field.
5. Save settings.

:::callout{intent="info"}
Omit your domain from the record values in Resend when you paste. Instead of
`resend._domainkey.example.com`, paste only `resend._domainkey` (or
`resend._domainkey.subdomain` if you're using a subdomain).

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

| Strato | Resend  | Example Value                |
| ------ | ------- | ---------------------------- |
| Type   | Type    | `TXT Record`                 |
| Name   | Name    | `send`                       |
| Value  | Content | `p=example_domain_key_value` |

:::callout{intent="info"}
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](../img/site-assets/mintcdn.com/resend/B7wTVm7aKL5pNT-6/images/inbound-domain-toggle-1by2oqa.png)

:::callout{intent="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](/guides/domains-knowledge-base-how-do-i-avoid-conflicting-with-my-mx-records).
:::

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](/guides/learn-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.

::::accordion-group
:::accordion{title="Resend shows my domain verification failed."}
Review the records you added to Strato to rule out copy and paste errors.
