How to Verify Any Email Address is Valid: Tips and Tools

This email validation API is one of the most advanced tools on the market, offering over 74 different data points to assess each email. Its speedy MX record verification helps ensure deliverability, while its anti-greylist tech and robust syntax checks catch common typos that can lower conversion rates. It also checks against a large database of disposable addresses to protect your list from phishing and spamming.

Users report that despite its impressive feature set, ZeroBounce can be slow to respond to support questions and has some inaccuracies in its results (e.g. some deliverable emails that it flagged as invalid turned out to be valid). It also has a high price tag, although a limited free trial is available.
