Because for some people, it might be better. Keep reading to get the key features, pros, and cons, and find out if this is a good tool for email verification.
What is Zerobounce email validation?
Zerobounce is an email verification service. They focus on checking if the email addresses on your list are correct and deliverable. This means that every invalid and outdated address is removed from a list.
It was established in 2015 and is trusted by many companies of all sizes.
Let’s see what users like about Zerobounce.
Zerobounce key features
Here are the most important features in Zerobounce.
Email validation
It’s the main feature of Zerobounce. They claim that their accuracy rate is 99%. According to third-party tools, the accuracy is about 98%, which is pretty close.
Zerobounce covers:
- Gmail accounts
- Yahoo accounts
- Catch-all addresses (although, the accuracy for them is quite low, only 58%)
- Disposable email verification
- Role-based account detection
- Greylisted email addresses
- Domain and MX validation
- SMTP verification
- AOL Account verification
- Removing duplicate emails
- Habitual complainer detection
- Honeypots/Spam traps
It’s worth mentioning that Zerobounce has an email scoring system. Using artificial intelligence, it assesses how subscribers will react to your emails.
However, the tool does not provide specific details on its accuracy rate for detecting spam traps.
Also, there is no explicit mention of how well it handles common email addresses from providers other than Gmail and Yahoo (for those two, the accuracy is 100%).
The speed
If you have a large email database, the speed of your email verification service is crucial. For one million emails, it can take days or hours to have a clean, verified list.
If your email validation process is slow, you might end up sending emails to invalid or other risky email addresses.
And unfortunately, it might not have a desirable outcome: email bounces, spam complaints, and even getting your emails marked as spam. That’s why you need to pay attention to this aspect as well.
Zerobounce takes 110 minutes to validate 10,000 emails (checked by the third-party tool – CleaningListAdvice). Which makes it pretty slow compared to other alternatives.
The integrations
Integrations help the tool work together with other programs and services you use. They get you connected directly to your email campaigns and other email deliverability tools.
You can check and clean your email lists right where you work without having to move your contacts around between different programs. It makes the whole process quicker and more convenient.
That’s why it’s always worth checking out the list of integrations when researching.
ZeroBounce includes 45+ integrations, for example, with MailChimp and Constant Contact.
In other words, there are plenty of integrations that an email marketing specialist will find useful.
Security
Zerobounce secures data by encrypting the files they run through their email verification tool.
The service complies with both the EU-U.S. Privacy Shield Framework and the Swiss-U.S. Privacy Shield Framework. They’re also GDPR, SOC2, and HIPAA compliant.

Complaints:
🛑 We had issues with our domain being restricted by other mail providers because of the number of mistyped or discontinued e-mail addresses on our mail lists.
🛑 The initial setup is quite difficult to understand.
🛑 My problem was an old email database. I wanted to be sure which emails were current and of those, which ones were likely to give a high bounce rate or cause complaints.
🛑 We have tried several spam email filter programs with disappointing results because, despite the configuration established, some spam emails arrived in the main tray.
🛑 Had to break up my 250K into smaller files to update. Too much trouble. Then after getting only approved emails and uploading them into Constant Contact we were declined due to too many bad emails.
