Configuration Guide

To configure a custom sending domain, you must have access to your DNS records. This way SparkPost - the service we use to send email messages - can prove that you're the owner of the domain. 

Request a feature activation from the Workshop Butler team

At this moment, we activate this feature on a per-account basis as there are still some manual actions we need to do. If you want to use a custom sending domain, write to us at

Add a custom domain

Update DNS records

As soon as you add the domain, the system provides you with instructions on what to do next. It should look like this:

Now it's time to go to a DNS panel and add two records:

  • TXT record
  • CNAME record.

After that, you'll wait for about 10-20 minutes and click Check Verification. This time is usually enough but it could take up to 24 hours for DNS records to update. 

Change Company Contact and From address

You may need to update your company contact and From address, if they belong to a different email domain that you added and verified. Workshop Butler lets you know about it.

The moment a verification is over and your company contact and From addresses are correct, Workshop Butler starts using your domain to send messages to your clients!
