What is a CNAME?
First things first: a CNAME (Canonical Name) is an alias for your domain. And you need to configure it correctly, to ensure that the emails sent via Prospect.io don’t bounce and are not marked as spam.
Why is it important?
To understand why the CNAME is so important, you need to know how we track email opens, and link clicks.
Each email that you send from Prospect.io contains a tracking pixel - a tiny invisible image, which we include in the body of every email. Your recipients can’t see it, but our system can track when the image is downloaded from our servers. This is how we know that the email was opened. The tracking pixel URL is rewritten with your domain when the CNAME is configured.
When you include links in your emails (either in the body or in the signature), we rewrite them, to track the clicks. A rewritten link has the following format but forwards to your URL when opened:
The CNAME allows us to use your domain instead of c.prospectrck.com on all the links.
Back to the point, it’s crucial to have the CNAME configured because modern spam filters are sensitive to such things as URLs in emails. Having all the URLs in your emails (the links that you added and the tracking pixel) pointing to your own domain increases the chances for your emails to pass the spam filters and to be delivered to the prospect’s mailbox.
How to configure the CNAME?
To set up your CNAME, you need to access your DNS settings. We suggest that you ask your IT team to help you as it is a technical and delicate operation.
The process consists of 2 parts:
- For your IT team: create a CNAME record in your DNS settings
- For you: enter your CNAME in your Deliverability settings.
