Why people choose ZeroBounce
With our guaranteed 99.6% accuracy and outstanding 24/7 support, it's easy to see why so many companies trust ZeroBounce. But we don't stop there. We adhere to GDPR, SOC 2 Type 2, CCPA and PCI protocols. Not enough? Here are a few perks available once you sign up for a free account.
High Accuracy
When you clean your email list with us, expect to get it back in excellent shape. Our email checker is 99.6% accurate - guaranteed. Companies like Amazon, Netflix and Sephora use it to avoid bounces and ensure their campaigns and newsletters make it to the inbox.
Top-Level Security
ZeroBounce is one of the most secure email verification platforms. You get military-grade protection for your data. Every file you upload is locked with an encryption cipher only you have access to. Also, we don't store your data and files for more than 30 days.
A.I. Catch-All Email Validator
Confused about your catch-all emails? ZeroBounce's AI Scoring helps you further validate them so you can nurture only the best contacts. This tool allows you to determine the potential validity of your catch-all emails and save solid leads you would otherwise toss.
Email List Enhancement
Where available, our email verifier adds missing data to your list - such as your customers' full name, gender and location. This improves segmentation and allows targeting specific groups with more relevant campaigns. The extra cost for this feature? Zero - we cover it.
Email Deliverability Tools
With ZeroBounce, you can test your mail server configurations and check that everything is set up correctly. Also, you can see where your email is going to be delivered with popular providers - before you send it to your list. If it's in Spam, you can edit and fix it until it arrives in the inbox.
Blacklist Monitoring
Blocked emails have no chance of landing in the inbox. Use ZeroBounce's blacklist monitoring tool to keep your IP and domain off blacklists. Our system checks daily against more than 200 email blacklists and notifies you if there's any sign of trouble - so you can get delisted.
No Charge for Unknown Results
Sometimes, certain email addresses can't be verified. They're usually invalid, but we'll mark them as "unknown" and never charge you for them. Also, you should know that ZeroBounce's email verifier returns the lowest number of "unknown" results in the industry. We ran tests against more than 50 competitors.
Free Deduplication
Keeping duplicates in your list is counterproductive. Your email service provider will charge you twice for the same contact. What's more, some people may report you as spam when they get your emails twice. Our email validator removes duplicate addresses in a heartbeat - at no cost.
29 status and sub-status codes
Did you think invalid emails are the only ones hurting your deliverability? ZeroBounce detects 29 types of risky email addresses. These poor-quality contacts prevent you from reaching the inbox and will sabotage your sales. Get granular data results so you can fine-tune and preserve your email hygiene.
Integrations
Email list cleaning should be quick and simple. We integrate with the most popular email, sales and marketing platforms, so you can easily import, validate and export your data. Explore our integrations and get started today by connecting ZeroBounce to the apps you use.
Team Accounts
Need the help of a colleague to keep track of your email verification? You can invite multiple users to your account and assign them different roles. Together you can check your credit balance, analyze results and remind each other when it's time to scrub your email list again.
