By Domain Tab for Email Tracking Report

The "By Domain" tab can be added to the Email Tracking Report to more clearly see your delivery stats based on the domain of the recipient email address. This will show the top 20 domains based on the total number of emails sent. This tab displays a grid view showing delivery stats including delivery rates, click rates, open rates, bounces, unsubscribes, and spam complaints broken down for each domain.

This feature can be particularly helpful if you would like to improve delivery for a specific domain. For example, if you see 0 delivered or 0 opens/clicks at a top domain, a next step would likely be to send instructions for whitelisting Critical Impact's IPs to that domain.

You can find instructions for whitelisting Critical Impact's IPs here: https://support.criticalimpact.com/hc/en-us/articles/360035106012-Whitelisting-Critical-Impact-s-IP-Addresses
