The Email Domains Report helps you understand where you’ve been sending email by showing a breakdown of recipient email domains and a count for each domain. Use this report when you want a clear view of your sending distribution across domains such as gmail.com, outlook.com, or corporate domains.

- Run the report to see a domain-by-domain count of recipients you’ve emailed.
- Use it to understand audience concentration across consumer and corporate domains.
- This report shows domain counts, not engagement or deliverability performance.
- Use segments (not new lists) if you want to target contacts by domain.
What the Email Domains Report shows
An email domain is the part of an email address after the @ symbol (for example, example.com). The Email Domains Report lists the domains you have sent email to and provides a count for each one.
This report is useful for understanding how concentrated your sending is across domains and for spotting unexpected patterns.
When would you run this report?
- You want a quick breakdown of the domains you’re emailing.
- You’re reviewing sending distribution for an internal check or audit.
- You’re investigating unusual results and want additional context about your recipient mix.
- You want to understand how much of your audience is on consumer domains versus corporate domains.
Run the Email Domains Report
To run the report:
- Go to Lists > Marketing Lists.
- Find the Marketing List you want & from the drop-down arrow on the right, click Mailings to List > Run Domains Report.
Understand the results
Each row in the report represents a single email domain, along with a count of recipients you emailed for the selected time period.
This report provides distribution and volume context. It does not show:
- Open or click performance by domain
- Deliverability metrics or reputation scoring
- Whether contacts exist in your database who were not emailed during the selected timeframe
How to use this information
Use the Email Domains Report as a visibility tool. A high count for a domain is not automatically a problem. It simply tells you where your sending is concentrated.
If you want to target contacts by domain, use a segment based on the email address field rather than creating additional lists. Keeping contacts centralised in fewer lists makes it easier to maintain accurate data over time.
