ZeroBounce Reviews & Product Details

I mainly use it for email verification. It’s easy to use and delivers reliable results. It also helps protect my domain’s integrity. Review collected by and hosted on G2.com.

Website sometimes has downtime. Not the cheapest solution. Results take up to 20 minutes to verify. I don't send campaigns without using it first, so downtime really slows me down. Review collected by and hosted on G2.com.

I find ZeroBounce very user friendly, and the UI is super easy to understand. I like the email verifier for checking emails before we send large emails. It helps us clean out old data before sending and helps with our numbers and email reputation. I also had a support ticket that was quickly jumped on, which is helpful when we're trying to get communications out quickly. It has been working seamlessly since we set it up.

Email finding cost can be reduced for regular customers. Review collected by and hosted on G2.com.

The email verification accuracy is very strong, and the platform consistently identifies invalid, risky, or disposable email addresses before campaigns go out. Since implementing it, we’ve seen noticeable improvements in bounce rates and overall deliverability.

The interface is clean and easy to navigate, so bulk verifications are simple even for non-technical users. The API integration has also been smooth, making it straightforward to automate validation workflows across forms and CRM systems.

Another major advantage is the added data insights, such as spam trap detection and email activity scoring. These features help us make better decisions around list hygiene and engagement. Review collected by and hosted on G2.com.

Pricing can add up if you’re working with very large databases or need frequent, high-volume verification. Also, some of the reporting and analytics views could benefit from more customization options and stronger filtering to make it easier to focus on what matters.

Quick and easy integration with HubSpot. Good detail of how/why they were validated. Flexible system with domain warming and other features to support. Review collected by and hosted on G2.com.

Understanding what was and wasn't included in the pricing took a minute. I needed to discuss with a rep prior rather than a fast and easy signup. Review collected by and hosted on G2.com.

I love ZeroBounce's fast API response speed and, above all, its high accuracy. It effectively distinguishes disposable emails and addresses likely to bounce, filtering email lists well. This allows us to verify validity before sending emails, reducing bounce rates. The API documentation is well-organized, and leveraging AI for development wasn't difficult, making setup easy, completed within 30 minutes. Compared to similar services, its accuracy is higher and more reliable, which is why I chose ZeroBounce. Review collected by and hosted on G2.com.

I want to call the ZeroBounce API from the registration stage to check for disposable emails, but the high number of API calls significantly increases costs, preventing implementation. If the pricing were more reasonable and competitive, I could adopt it more widely. Review collected by and hosted on G2.com.

I like that ZeroBounce is easy to use and that the API is reliable and simple—it just works and does what it says it will do. I can tie it directly into our AI tools and workstreams, where it fits into our go-to-market setup as infrastructure and helps make the workflows efficient. It’s pretty cost effective, too. When it says an email address is active and working, it’s damn near 100% accurate. Setup was very easy, and it helps us reach the specific people we need without the friction of not having their direct contact details. Review collected by and hosted on G2.com.
