A Health Scan for Your Email Addresses!


Free List Check is a tool to get a high-level report of the health of an email list. It will identify if the list has any problems with:
  • Invalid Addresses
  • Spamtraps
  • Forced Signups
Free List Check can help you:
  1. 1. Prevent bad data from entering your platform, by checking a list before you add it to your database.
  2. 2. Conduct manual or regular checking of your existing data, to protect the reputation of your IPs and sending infrastructure.
  3. 3. Get an overview of your data hygiene and acquisition practices and determine if your list should be cleaned before hitting send.
No cost, Free List Check is completely FREE to use.
This site is powered by us, the email address experts at FreshAddress, LLC. We help companies clean, protect, and grow their email lists. We want you to get an idea of what we're capable of, so Free List Check is a chance for you to get a quick peek of why we're "The Email Address Experts".
While you won't get line by line findings, you will get an alert if your list has problems with invalid addresses, spamtraps, or forced signups. The email report looks like this.
A spamtrap is a valid, deliverable email address that is exclusively used to receive unsolicited email. If you send messages to a spamtrap, you could damage your sending reputation and end up on a blacklist. Read more

Yes, the security of your data is our top priority. Your list is processed in memory and not stored. Our processes and services comply with the strictest of data standards, including Europe's General Data Protection Regulation (GDPR).
To protect the confidentiality of our databases and sources, it is necessary for us to enforce a minimum list size.
We restrict list sizes to keep this service free and have available capacity for all those who need it. However, if you choose to run a paid job with FreshAddress, there is no limit in the size of the list you can run! 😊
