"Super easy to use. I love that they give you flexible options instead of locking you into a plan."
What do you like best about ZeroBounce?

What I like best about ZeroBounce is how simple the platform is and how fast the verification reports are delivered. I also appreciate the flexibility—no forced monthly plan, just pay for what you need. Review collected by and hosted on G2.com.

What do you dislike about ZeroBounce?

I honestly don’t have any real dislikes. I still get a few bounces here and there, but it’s nothing compared to what I would receive without using ZeroBounce. Review collected by and hosted on G2.com.

"Very helpful to us"
What do you like best about ZeroBounce?

The automation of our list validation processes in Klaviyo. Keeps us from emailing new subscribers who mistyped their email or otherwise submitted a bad email when buying or requesting info. The grading system on our emails is helpful because we use it for generating segments for our email marketing. Review collected by and hosted on G2.com.

What do you dislike about ZeroBounce?

nothing so far has been a problem. I am very satisfied. Review collected by and hosted on G2.com.

"For Cold Email Campaigns It's Perfect"
What do you like best about ZeroBounce?

Mostly the quality and the speed. I use it for Cold Email Campaigns, and I never have a single email bounce back. Review collected by and hosted on G2.com.

What do you dislike about ZeroBounce?

I can understand that for beginners it might be a bit expensive, and that makes the first step a bit harder to get it, but once you have it you'll see it's worth it. Review collected by and hosted on G2.com.

"ZeroBounce Improves email deliverability and protects my domain"
What do you like best about ZeroBounce?

I've used my customer list for about five years. Maybe longer. I validate it through ZeroBounce to remove invalid email addresses. Their process of uploading my list is simple and the results are fast. Review collected by and hosted on G2.com.

What do you dislike about ZeroBounce?

Some of the services are not clearly explained, for instance, email warmup. I read their website material but still I need to speak with a representative to understand what it is more clearly. I think the author assumes that everyone knows what they do. Review collected by and hosted on G2.com.

Response from Corina Leslie of ZeroBounce

Thank you so much for the feedback, Richard! We've passed it along to our content team so they can revise the wording and make email warmup easier to understand for everyone.

Nice job on cleaning those invalid emails and keeping your reputation strong! Please reach out whenever you need us -- we're available for you 24/7.

There's a lot in the dashboard - a lot of features to get the most out of ZeroBounce. Ultimately, it is down to me to spend the time understanding how I can best employ the features. Review collected by and hosted on G2.com.

"We've been using ZeroBounce to clean and verify our contact database of nearly 50,000 leads."
What do you like best about ZeroBounce?

We've been using ZeroBounce to clean and verify our contact database of nearly 50,000 leads, and the results have been excellent.

The platform is intuitive, fast, and highly accurate. Within minutes, we were able to:

Identify and remove invalid or outdated emails

Reduce our bounce rate significantly

Tag catch-all, abuse, and role-based emails to improve segmentation

Protect our sender reputation across HubSpot and outreach campaigns What really stood out was the depth of detail in the results and how easy it was to integrate with our workflows. It gave us the confidence to launch reactivation sequences and cold outreach with cleaner, more reliable data.

If you're running outbound at scale and want to maximize deliverability and engagement, ZeroBounce is a no-brainer. Highly recommended for any sales or marketing team serious about results. Review collected by and hosted on G2.com.

What do you dislike about ZeroBounce?

Nothing, we love it! We recommend it! XO Review collected by and hosted on G2.com.

Response from Corina Leslie of ZeroBounce

Thank you so much for the incredible feedback! It means a lot to hear how ZeroBounce helped you clean your list. We’re thrilled the platform fits so smoothly into your workflow and delivers the accuracy and detail your team needs.

We’re here anytime you need us - cheering you on for those big results!

"Fantastic Email Validation Tool"
What do you like best about ZeroBounce?

Having used other email validation tools in the past, I've been particularly impressed with the level of granularity in the details provided with ZeroBounce. With other software, the validation responses were extremely limited, but with ZeroBounce, we've been able to actually quantify spam traps that were affecting our database health. I also feel like we have a higher % of validation than we did with some other tools, where we saw extremely high volumes of unknown/unverifiable emails. Review collected by and hosted on G2.com.

What do you dislike about ZeroBounce?

I love that ZeroBounce has the option to score catch all emails, but having to pay double for those contacts does add up over time. With some other tools, we only had to pay once to validate an email address (if it wound up in a future list), but with ZeroBounce, if you upload a contact that has already been validated, you will be charged each time. This requires some manual work to remove contacts we've recently validated so we don't re-pay for them in a short period of time. Review collected by and hosted on G2.com.

Response from Corina Leslie of ZeroBounce

Thanks so much for this detailed review. We're really glad to hear that the insights from our validation results have helped you improve your list!

We hear you on the catch-all scoring costs and repeat validations. Our team is always exploring ways to make things more efficient for our users, and feedback like yours is very valuable.

Thanks again for trusting ZeroBounce!

"Does Exactly What You’d Hope – My Experience with ZeroBounce"
What do you like best about ZeroBounce?

What I like best about ZeroBounce is that it just quietly gets on with the job. No faff, no fluff – it’s straightforward, does what it says on the tin, and keeps my email list clean as a whistle. The accuracy’s been spot on so far, and it’s saved me a right headache when it comes to bounces and spam traps. Proper useful bit of kit, really. Review collected by and hosted on G2.com.

What do you dislike about ZeroBounce?

If I had to nitpick, I’d say the dashboard can feel a bit clunky at times – not the end of the world, but it could do with a bit of a tidy. Review collected by and hosted on G2.com.

Response from Corina Leslie of ZeroBounce

Thanks so much for your thoughtful review! We're glad ZeroBounce is doing exactly what you need it to.

We'll pass your dashboard feedback along to our product team, too. It means a lot that you took the time to share this!
