ISP by domain
What this tool does
This tool looks at a domain name to identify which services handle its incoming and outgoing emails. It checks the domain's public technical settings to see which platforms are used for receiving mail and which are authorized to send it.
Important: The results are based on public settings configured by the domain owner. These settings can be changed at any time, so the information might not reflect real-time activity or the actual current setup if the owner has not updated their records.
Common uses
- Verifying which email provider (such as Gmail or Outlook) a company uses for its corporate email.
- Checking if a domain is set up to send marketing emails through specific platforms.
- Understanding the email infrastructure behind a website's contact forms.
Note on cost
0.010 credits per call. The cost is charged even when the tool returns an error or does not find a result.
