ZeroBounce ONE™

Zerobounce Enterprise

Executive Officer

The zerobounce platform has enabled me to effectively screen my mailing list thereby reducing the incidence of email bounces and erroneous labelling of my email as spam.

When listing emails, the system is unable to smartly identify and predict points of errors such as omission of domain name or '@' symbol on each line

Director, Email

It made list hygiene easier by quickly identifying obvious bad addresses and highlighting risky segments (spamtraps/abuse/unknown). Once you define internal rules for how to treat catch-all and other edge cases, it becomes a strong, repeatable part of an email deliverability workflow.

Marketing Ops and CRM Specialist

One thing I appreciate about ZeroBounce is its clean and straightforward design — everything is organized in a way that makes navigation simple, even for new users. While the platform doesn’t offer extensive design customization, the existing layout is already very polished and efficient.

Marketing Director

The speed of processing is impressive, and for a standard verification tool, it offers a reliable service that integrates well with our existing marketing workflow.

Customer Engagement Manager

This "set it and forget it" workflow that saves us hours of manual data managementIt has helped reduce bounce rate and improve our email health.

Additionally, some of the validation categories require interpretation, which can create minor uncertainty around borderline results if you are new to email verification tools.

Marketing automation manager

For example setting the exact hour that you want the dailly validations to happen OR to have validations as soon as a contact is added to a list in Hubspot.

Most dashboards and views follow a fixed layout, so users can’t personalize how metrics or verification results are displayed.

Sales Manager

Accurate email validation, fast processing, and clear reports that reduced bounces and improved our outreach efficiency.

It performs exactly as expected and integrates well into outreach workflows, helping protect sender reputation and improve campaign performance.

Chief Operating Officer

The pricing can start to get expensive as your email list grows and you use the service more often, but the accuracy and reliability make it well worth the investment for maintaining high deliverability.

While ZeroBounce is reliable for verification, the platform can feel a bit limited for email marketers who want deeper insights beyond basic validation.

Some features feel a bit gated behind higher tiers/credit usage, so costs can add up if you rely on multiple enrichment checks.

Lead Team

ZeroBounce delivers exceptional accuracy with their email validation service, and their customer support team is incredibly responsive and knowledgeable whenever I needed assistance.

Marketing Analyst

The only downside is that the pricing can feel a bit high for smaller lists, and some advanced features take a little time to fully understand at first.

Sr. Executive

However, in the valid list, first name and last name fields are often missing or blank, so additional work is needed to enrich the data.

Marketing Operations Manager

It is an exceptional tool for maintaining list hygiene, email validation and improving deliverability.

Developer

We connected it to our Klaviyo account and the integration was super quick—it took only a couple of minutes to get everything up and running.

Some valid records have missing first and last name fields, so additional effort is required for data enrichment

However, the default design is efficient enough that it doesn’t hinder daily tasks — more customization would simply make it even better.

Demand Gen Lead

The platform makes it very easy to upload and process large files, and the scoring and validation insights are clear and helpful.

I am using for validation it is the best if you are finding the emails in bulk you can go with it,will help you alot.

The dashboards are clear, the data is easy to read, and the overall interface keeps the focus on what matters most: verifying emails quickly and accurately.

Director of Analytics

It seems like my catch-all scores should be higher and the catch-all scoring now takes 2 days when it used to be faster and I'm still getting the same yield

Lifecycle Marketing

It can be a bit frustrating when a definitive valid or invalid status is not provided, especially when cleaning larger lists.

Helpful add-ons like activity/engagement and IP/domain checks that go beyond basic validation.

Marketing

ZeroBounce is favored for its high accuracy in email validation, user-friendly design, comprehensive features, excellent customer support, and robust security measures, making it a valuable tool for businesses focused on effective email marketing campaigns.

CRM and Automation Manager

The platform helps reduce the risk of sending emails to addresses that don’t exist or are unsafe.

Head of US Marketing

I don't like that so many of my contacts come back as unverified, but that is a good problem to have helps verify lead quality.

It’s a professional-grade tool that does exactly what it promises: it stops bad data from polluting our email health.

Managing Director

Lots of services, but the one I actually wanted, the validation, is superb and more thorough than any of the other big names I'd used.

COO, Chief Strategy Officer

Really helps us extend the size of databases and increase the effectiveness of targeted marketing.

It significantly reduced bounce risk in our outreach campaigns and improved deliverability rates.

Head of Growth

Would love if it generated just one file instead of 8 with the results, it would really simplify things for me.

Sales Director

Maybe we could get an email with the results so we store them at our own will in our inboxes.

Head of growth

perferct, as it's easily integrated with our internal systems and can be easily integrated with zapiar

Market development manager

The accuracy of email validation, detailed reports, and the ease of cleaning large lists boosted campaign deliverability.

Product Manager

The thing I liked the least is that the interface feels a bit clunky and there are almost too many features that seem non-core.

VP of Marketing

At the beginning of our project, there were no Microsoft 365 seeds, which is our primary need.

During onboarding, they took the time to walk us through everything and explained things clearly so we could get the most out of the platform.

Partner

Its a no nonsense application that is easy to use, validates the addresses and lets me move on with my work in timely manner.

Event Coordinator

Some results need extra context (e.g., “catch-all”), so it can take a moment to interpret.

Salesforce Consultant

b. Need to increase the limit for making API calls per minute, especially when working with large data volumes, as we need to adjust waiting times accordingly.

The integration works well, but adjusting the daily sync could be improved.

Partnership Manager

I use it daily to verify emails, the fact that it removes duplicate entries on lists is also great

Investment Coordinator

I have been able to reduce our email marketing bounces by approximately 20% since using it.

Assistant manager marketing

A few results occasionally come back as “unknown” which can be frustrating when you’re trying to clean a list completely

Sales Development Team Lead

It would be nice to keep it in-platform, or have some AI functionality for processing the results

Processing speeds can also be slower compared to some competitors, which might be frustrating when you need quick turnaround times for large email lists.
