What is ZeroBounce?

ZeroBounce is an email validation and deliverability platform. Its suite of services helps business users avoid spam folders and land emails in customer inboxes. The software scales to support enterprises and offers personalized onboarding, email validation training, and 24/7 support. The software is free to use for up to 100 emails. Monthly or pay-as-you-go pricing is available.

Email validation and catch-all email scoring

ZeroBounce boasts a 99% accurate email validation service that removes invalid, outdated, toxic, and bot-created email addresses from databases. Email list validation ensures senders use healthy email lists so they can avoid the spam folder and reach their customers. ZeroBounce also adds metadata to email addresses. The software appends the name, gender, and geolocation of a contact (where available). Aside from email validation, ZeroBounce also provides an email scoring tool that further validates catch-all emails.

Inbox placement tester

ZeroBounce allows users to test their emails before sending and identify potential email deliverability issues ahead of time. By using 20 testing email addresses provided by ZeroBounce, users can find out whether their email lands in the inbox or the spam folder of commonly-used email providers.

Email server tester

ZeroBounce’s software reveals any email server misconfigurations that could prevent emails from reaching the inbox. The email server tester pinpoints technical issues before they start sabotaging email marketing ROI.

Blacklist checker

Blacklist monitor

I use ZeroBounce to verify the email addresses of current customers and the email addresses that I get from my prospecting processes. I make sure that the email address is valid so that I am not wasting my time sending emails to people who aren't within that org, company, or agency anymore. I also use it to help support the 3 other salespeople that I work with. It is extremely easy to use and the UX/UI of the page is great! The only thing I don't like about it is having to sign in on a daily basis, due to inactivity when I am not working.
  • Ease of Use
  • Accurate details regarding the validity of the email address
  • Cost-worthy pricing plans
  • Creating a Mobile App or Desktop App that would prevent occurring logins.
It is easy to justify the expenditure, due to the fairness of pricing plans and the UX of ZeroBounce. It is extremely accurate and easy to use.
  • Accuracy of email address deliverability
  • Saves a ton of time in prospecting and marketing efforts
I can't remember previous services that I have used, but I do know that I have used 2 or 3 others. ZeroBounce isn't complicated to use, doesn't restrict my use, provides reasonable pricing, and is accurate.

ZeroBounce is now our only email verification company. We use massive email campaigns to help our clients promote their crowdfunded offerings and drive traffic to their investment page. Our clients provide us with their email lists that are often old and outdated, so they need to be cleaned of dead emails. One thing that ESP's HATE is a list that contains bad emails. Before we used ZeroBounce we once had an account suspended because it contained too many emails that were no longer good. We learned our lesson, and now we deliver exceptionally clean lists to our ESP.
  • ZeroBounce provides us with not only valid emails but also separates the catch all addresses
  • Their security is probably the best in the world
  • Their support is exceptionally responsive
  • They are more economical than our previous provider
  • I wish they had a way to actually create the emails
  • We've worked with ESP's that have good templates and I wish ZeroBounce has those
  • The security is SO good that it can be a little troublesome
ZeroBounce should be used to verify all emails prior to sending ANY campaign. I can't think of any scenario where it should NOT be used. All campaigns that include massive emails really need to be verified for correct email addresses or will chance being suspended by your email Service provider.
  • Great support
  • Economical
  • Easy to use
  • We have had a good response from our emails
  • We have not been suspended by our ESP
  • We have impressed our clients

We develop databases of potential decisionmakers for sales/marketing departments who are implementing Account-Based Marketing. Because these databases are an integral part of their sales and marketing campaigns it is critical that they are as close to being 100% accurate as possible. Particularly critical are the e-mail addresses, as e-mails are the primary method our clients stay in constant communication with their prospects. Companies who demonstrate high bounce rates or spam are greylisted which means their e-mails to their customers don't get delivered and end up in the spam folder. My reputation depends on us creating databases that our clients depend on. We use ZeroBounce to make sure we deliver quality databases 100% of the time.
  • Ease of use.
  • Speed of checking databases.
  • Will detail is good, could always be better regarding identifying specifics of database issues.
  • Would love an app to check progress or reports on the go.
We use it in combination with another resource to check e-mail quality of databases before delivering the finished product to our client, by using a two-step process we consistently deliver databases with 100% accuracy. We have found that it is critical to use this two-step approach to ensure 100% accuracy. We have tried short cuts and ended up disappointed with the results.
  • Clients appreciate that ZeroBounce is incorporated as part of our quality control.
  • It's a great selling feature knowing that we are taking extra steps to ensure 100% accuracy.
Our client was already using BriteVerify and we felt strongly that this gave us another layer of verification to cross-check against hard bounces/spam. Our client was adamant about receiving a list with 100% accuracy so there would be no chance of spam/greylisting e-mails that prospects were receiving from our client's marketing team.
We have used ZeroBounce for about 18 months and it works flawlessly. We are able to get all of our questions/issues answered immediately. Felt very comfortable with the product immediately - used their web site which walked us through it and were able to get up and running within minutes. I really haven't had any issues that required support.

We use it to remove emails that will bounce in our system. This is critical for keeping a healthy database.
  • Improve email
  • Deliverability
  • Clean database
  • Not 100% accurate
ZeroBounce is perfect for list cleaning before sending out to prospects, cleaning out people from Salesforce or marketing automation systems, and ensuring emails are always up to date.
  • Not connected to any other email tool which makes you have to buy another tool.
  • You can send duplicates through which is not effective.
  • Also saves a bunch for cleaning databases for bad emails.
I personally like Briteverfy better because they have phone and address matching.
I didn’t get much support so I couldn’t give a better rating, but I’m sure it is good.
