Testimonials for ZeroBounce’s email address validity software
"Their support has been awesome, the UI/UX of their client portal is great. So far my experience has been great. I had heard that they are a little more expensive then their competitors BUT THAT THEY ARE WORTH IT because their email cleaning results are best in industry. So far that seems to be the case, and in this specific area it would not be worth it to try and save a few pennies to go with someone cheaper."
Owner/CEO Events Services
"Very simple to implement. I just upload a CSV file and ZeroBounce handles the rest. It's a quick process to scrub lists before launching my email campaigns."
"I like using ZeroBounce because it's super easy to use. The reported results are segmented into separate spreadsheets and are straightforward and easy to understand. The results also include any data ZeroBounce has gathered on each contact in the past. Finally, the cost is more than competitive."

Frequently asked questions about email validity
Validity refers to whether an email address is valid or invalid. A valid email address is one that exists and is currently in use. Meanwhile, an invalid email address either doesn’t exist or has since expired.
You can check the validity of an email by using an email validation tool. You can do this in a variety of ways, including using a pre-existing validation library for a language like JavaScript or by using a dedicated service. An email validation service will have the resources to validate a large volume of emails rapidly while also performing additional checks like domain pinging or DNS record lookups to ensure that the address exists and the domain is configured to receive mail.
Your email validity analysis will provide the status of the email address entered (valid, invalid, etc.) as well as any relevant sub-status information (disposable, toxic domain, etc.). In addition to this, the analysis may also include details such as the domain age, SMTP provider, MX record details, and the name of the address owner.
