Software to check email addresses is a key part of ensuring that your lists are free from fake, invalid or otherwise undeliverable email addresses. This is done through a combination of standard validation techniques and, depending on the software used, proprietary algorithms. Email verification can be performed as a standalone desktop tool or hosted online service, which is often preferred since it does not require an IP address to verify addresses and is easy to support and update.
The Best Software to Check Email Address Validity and Accuracy
Some of the best software to check an email address is free and offers both instant and bulk email validation. This includes Clearout, which is well-known for its accuracy of 98%+ and extensive set of validation checks, including syntax checking, domain/MX records, catch-all servers, spam trap detection, role-based account detection, and reachability testing. Clearout also offers a Google Sheets add-on and an API for high flexibility, making it possible to integrate email validation into any software application written in any programming language.
Another good free option is ZeroBounce, which offers a very user-friendly interface and fast turnaround on both instant and bulk verification. Its standout feature is that it separates the results of each list into categories, including valid, risky, unknown and disposable. It also has a great search functionality that can find professional contacts from any website by simply searching for their company name. This makes it easier than ever to keep contact lists clean and up-to-date. For more advanced features, ZeroBounce can be upgraded to a paid plan with monthly rates based on credit amount.
