Online email verification checker is an important step in ensuring your contact list contains valid, accurate email addresses. Invalid emails waste time and resources, lead to high bounce rates, damage your email sender reputation and decrease the effectiveness of your marketing campaigns. Invalid emails are also more likely to end up in the spam folder, preventing your messages from reaching their intended recipients.

An online email verification checker is an easy way to identify invalid emails, such as typos or syntax errors, and weed out risky addresses that may be temporary, disposable or catch-all. These tools connect directly to the server over SMTP and simulate sending an email, verifying whether an address exists, is accepting incoming messages and is a good candidate for sending to. Some of these tools also offer advanced features, such as analyzing the behavior of an email address over time, detecting patterns in how an address is used and identifying potential spam traps.

Online Email Verification Checker: Quick and Easy Solutions

The best email verification software checks for the format of an email address, identifies possible spelling errors and verifies the domain name. Additionally, many of the best tools include a feature that removes stale, inactive, disposable or fake email addresses from your list. A quality tool will also look for spam traps – addresses set up by ISPs and ESPs to capture senders who don’t follow proper list hygiene practices. These are particularly common in purchased lists and can be a serious problem for marketers.
