# Cloudflare

## Add Domain to Resend

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

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.

## Automatic Setup (Recommended)

The fastest way to verify your domain on Cloudflare is using the **Sign in to Cloudflare** button on Resend. This uses Domain Connect to automatically configure your DNS records.

1. Go to your [Domains page](https://resend.com/domains) in Resend.
2. (Optional) If you want to receive emails, select `Manual setup` and toggle the "Receiving" switch on the domain details page. ([Learn more below](#receiving-emails))
3. Click **Sign in to Cloudflare** button.
4. Authorize Resend to access your Cloudflare DNS settings.
5. The DNS records will be added automatically.

That's it. Your domain will be verified within a few minutes.

## Manual Setup

If you prefer to add DNS records manually, follow these steps.

### Log in to Cloudflare

Log in to your [Cloudflare account](https://cloudflare.com) and go to the DNS Records of your domain.

### Add MX SPF Record

Click "Add Record" on Cloudflare:

1. Set the Type to `MX`.
2. Type `send` for the `Name` of the record.
3. Copy the MX Value from Resend into the `Mail Server` field.
4. Use the default `Auto` for `TTL`.
5. Add `10` for the `Priority`.
6. Select `Save`.

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

| Cloudflare  | Resend   | Example Value                           |
| ----------- | -------- | --------------------------------------- |
| Type        | Type     | `MX`                                    |
| Name        | Name     | `send`                                  |
| Mail Server | Content  | `feedback-smtp.us-east-1.amazonses.com` |
| Priority    | Priority | `10`                                    |

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

:::callout{intent="info"}
Do not use the same priority for multiple records. If Priority `10` is already
in use, try a higher value `20` or `30`.

### Add TXT SPF Record

Click "Add Record" on Cloudflare:

1. Set the Type to `TXT`.
2. Type `send` for the `Name` of the record.
3. Copy the TXT Value Resend into `Content` field.

![Domain Details](../img/site-assets/mintcdn.com/resend/ABWmVTZIHGIFNTFD/images/dashboard-domains-cloudflare-dkim-txt-1def4ws.png)

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

| Cloudflare   | Resend  | Example Value                |
| ------------ | ------- | ---------------------------- |
| Type         | Type    | `TXT`                        |

| Target       | Content | `p=example_domain_key_value` |
| Proxy Status | -       | `DNS Only (disabled)`        |
| TTL          | -       | `Auto`                       |

:::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).
:::

### 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).
:::

Click “Add Record” on Cloudflare:

1. Set the Type to `MX`.
2. Type `inbound` (or whatever your subdomain is) for the `Name` of the record.
3. Copy the MX Value from Resend into the `Mail Server` field.
4. Use the default `Auto` for `TTL`.
5. Add `10` for the `Priority`.
6. Select `Save`.

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

| Cloudflare  | Resend   | Example Value                          |
| ----------- | -------- | -------------------------------------- |
| Type        | Type     | `MX`                                   |
| Name        | Name     | `inbound`                              |
| Mail Server | Content  | `inbound-smtp.us-east-1.amazonaws.com` |
| Priority    | Priority | `10`                                   |

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 up to 72 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="Cloudflare returns 'Code: 1004' when adding CNAME Records."}
Confirm your proxy settings are set to `DNS Only` on the record you are adding.
:::

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

:::accordion{title="It has been longer than 72 hours and my domain is still Pending."}
