It pays to keep a clean email list, and email verification makes it fast and easy. But how do you choose the best email verifier? If you’ve stumbled upon this page, you’re probably trying to pick between ZeroBounce and FreshAddress. Below we give you all the info you need to make a choice – take a look and reach out to us if you have any questions.

Note: FreshAddress has changed its name and is now called AtData.

How does ZeroBounce compare to FreshAddress?


ZeroBounce and FreshAddress both detect invalid, spam trap, abuse, disposable and catch-all emails. Also, both email checkers enhance your email list with metadata. However, ZeroBounce appends more missing information to your list of contacts, such as gender and IP.

You’ll notice other significant differences between the two email validators.

For instance, FreshAddress does not disclose whether it removes duplicate contacts for free, which is something ZeroBounce does. Furthermore, FreshAddress doesn’t offer 24/7 customer support, a perk that anyone who visits zerobounce.net can enjoy. ZeroBounce provides assistance via phone, email or live chat.

How about accuracy? ZeroBounce guarantees 98% and FreshAddress promises 100% deliverability on your emails. However, you won’t get a refund from FreshAddress in case some of your emails don’t make it to the inbox.

ZeroBounce further validates catch-all emails


Many email validation services can detect emails associated with catch-all domains. However, it’s one thing to detect them and another to validate them.

Catch-all emails are set up to accept any incoming message to that domain, even when the ID is incorrect. Certain organizations set their domains this way to ensure they don’t miss any communication.

While they fulfill their purpose, catch-all emails are risky to mass senders. Due to their nature, these mailboxes can get full quickly and cause a soft bounce. What’s more, the administrators of that domain can turn off the catch-all function at any time, which would result in a hard bounce.

Both ZeroBounce and FreshAddress can identify catch-all domains. But ZeroBounce gives you an alternative way to validate catch-all emails: email scoring.

ZeroBounce Score investigates the activity of catch-all emails to determine their potential validity. The score it returns ranges from 0 to 10 – with 10 indicating the highest likelihood of validity. FreshAddress does not provide this type of service, nor does it give you access to other email optimization tools.

Email deliverability tools at ZeroBounce and FreshAddress


Using an email validator is a great way to start improving your inbox placement. But you can do even more to reach your customers, and certain platforms – like ZeroBounce – give you access to a variety of tools.

ZeroBounce’s email deliverability toolkit includes:

• an email server tester, so you can make sure your mailing server is set up correctly

• an inbox placement tester that allows you to test your email deliverability before you send

• a blacklist monitor that alerts you if your IP and domain are ever found on a blacklist

Apart from that, ZeroBounce’s Activity Data feature gives you insights into the overall email activity of your subscribers. It detects opens, clicks, forwards and unsubscribes, so you can find out how many of your subscribers have had recent activity, then segment and target them with a campaign.

FreshAddress does not provide any such tools. The table below paints a clear picture of how the two email verification platforms compare.
