Adding your own email sending domain is a great way to segment your email traffic, keep your links on-brand, and improve deliverability. To do so, you'll need to connect Clearstream to your domain provider by creating new DNS records.

Open your DNS Records in your provider

First, you'll need to open your DNS records in your domain provider (we made specific guides for how to add DNS records for GoDaddy, NameCheap, and Squarespace). In general, the process is:

Log in to your provider.
Navigate to your domain.
Open the DNS records.

Keep your domain provider open, then follow the steps below.

Open your Custom Domain settings in Clearstream

Next, in a new tab, you'll need to open your custom domain in Clearstream. This will allow you to easily copy and paste the new DNS records into your domain provider.

Quick Steps: Log in > Settings > Email > Set up next to Custom Domain.

Log in to your Clearstream account.
Go to Settings in the left menu.
Click Email.
Click Set up next to Custom Domain, and keep the tab open.

Add the DNS records

You'll need to toggle back and forth between your domain provider and Clearstream, so we recommend keeping both tabs open side by side.

Sign your emails (DKIM)

This record adds a hidden signature to your emails that verifies they came from you and were not tampered with after sending.

(Domain provider) Click Add New Record, then enter the Type as CNAME.
(Clearstream) On the Domain Settings page, look at the first row of information under Sign your emails (DKIM).
Copy the information under Name into your domain provider. Then, copy the info from the Value column into your domain provider.
(Domain provider) Click Save to add the new record.
Repeat the above steps for the second and third CNAME rows.

Authorize Clearstream as a sender (SPF)

This record tells email providers that Clearstream is allowed to send emails on your behalf.

(Domain provider) Click Add New Record, then enter the Type as MX.
(Clearstream) On the Domain Settings page, look at the first row of information under Authorize Clearstream as a sender (SPF).
Copy the information under the Name and Value columns into your domain provider. Then, copy and paste the Priority information.
(Domain provider) Click Save to add the new record.
(Domain provider) Click Add New Record, then click Type, then select TXT.
(Clearstream) Look at the second row under Authorize Clearstream as a sender (SPF).
Copy the information under Name into your domain provider. Then, copy and paste the info from the Value column.
(Domain provider) Click Save to add the new record.

Protect against spoofing (DMARC) (Optional)

This record tells email providers what to do with emails that aren't verified or sent by Clearstream, so spammers can't spoof your email address. This is recommended, but not required.

(Domain provider) Click Add New Record, then enter the Type as TXT.
(Clearstream) On the Domain Settings page, look at the first row of information under Protect against spoofing (DMARC).
Copy the information under Name into your domain provider. Then, copy and paste the info from the Value column.
(Domain provider) Click Save to add the new record.

Track opens and clicks using your domain (Optional)

Routes open and click tracking through your domain instead of Clearstream's shared domain. We recommend doing this to improve deliverability, but you don't have to.

(Domain provider) Click Add New Record, then enter the Type as CNAME.
(Clearstream) On the Domain Settings page, look at the first row of information under Sign your emails (DKIM).
Copy and paste the information under the Name and Value columns into your domain provider.
(Domain provider) Click Save to add the new record.
