Note: This is an advanced article. If you aren't comfortable customizing your DNS records (or don't know what they are) you should not proceed. You can also hire a Certified Expert to help you get set up!

Getting Started

Your deliverability is based on two things: 

  1. The reputation of your email marketing provider.
  2. Your own domain reputation.

One thing we offer is the ability to set up a verified sending domain, which allows you to set up authentication records with your web host. This tells email providers like Gmail and Outlook that you are a real business, and you have given ConvertKit permission to send using your domain on your behalf.

To set this up, you'll need a basic understanding of CNAME records.

These records are not required, but can improve your deliverability to your Subscribers!

How to request a verified sending domain!

To get started:

  1. Send us a message and that tell us your domain name and ask to verify your domain. Do not make any changes or additions to your DNS settings before you contact us! 
  2. We'll reply with the values to add to your DNS records.

Configuring your records

Once you get that information, you need to configure your records with your DNS. This is typically done through your host or domain registrar (,,, etc.). Instructions here may vary (check with your host support if you get stuck). 

Do I need to set up a subdomain?

Short answer: no. 

We ask you to set up your CNAME records on a subdomain of your domain, instead of the top level domain. This prevents your authentication records from interfering with your top level domain, but it doesn't require the extra work of setting up a separate subdomain. You just need to make sure your hostname for each record is exactly what we provide. 

If your DNS provider is suggesting you set up a totally separate subdomain, let us know and we can take a look at your specific situation!

Write back to ConvertKit Support

Once you're done with that send us an email to let us know. We'll do some work on our side to configure your email to send through the new domain. After that you'll be good to go!
