Do my credits ever expire?

Credits never expire while you have an active ZeroBounce One™ subscription. You can continue using your available credits at any time during your subscription. If you don’t have a ZeroBounce One™ subscription, expiration rules may apply depending on when your account was created, or when the credits were purchased, granted, or received as part of a promotional campaign. Please refer to the applicable terms for details or contact your account manager.

Will you charge me any credits for “unknown” results?

No, we will never charge you for “unknown” results. For various reasons, sometimes we’re unable to verify an email address. That’s when you’ll get an “unknown” result. Most often, those email addresses are risky, but we won’t charge you for checking them, nor will we charge you for removing duplicate email addresses from your list.

Pay as You Go vs. subscriptions. What’s the difference?

Our Pay as You Go option starts at $39 USD for validating 2,000 email addresses. It's our minimum purchase. You can add on credits as you need. Our ZeroBounce ONE™ subscription is available at $99 USD a month. Depending on how many emails you need to validate, a subscription can save you up to 18% every month. Also, unused credits roll over each month. You can cancel your subscription anytime.

How quickly can you clean my email list?

It depends on how many email addresses you have. To give you an idea, ZeroBounce cleans 100,000 email addresses in 45 minutes.

Do you store or share my data?

No, we never store your data in our system for more than 30 days. All your data and aspects of your data are erased 30 days after you upload your file, unless you choose to delete it before that. Also, the information you share with us for payment purposes is encrypted.

What makes ZeroBounce different from its competitors?

Several aspects make ZeroBounce stand out. Our guaranteed 99.6% accuracy, military-grade secure system, and 24/7 customer support are just three of them. What’s more, ZeroBounce has evolved into more than an email validation platform. With the addition of our ZeroBounce ONE™ package, you can now verify and enhance your email list, and access all the tools you need to boost your inbox placement.

How many credits will I need?

You’ll use ZeroBounce credits for several different services. For most services (email validation and Scoring), we charge one credit per email address. For example, to validate one email address, you will use one credit. To score that same email address, you’ll spend an additional credit. If you’d like to validate, score, and add Activity Data to the same email address, you’ll consume two credits. If you choose to score your email list after uploading it for validation, you’ll spend one additional credit for each scored email address. We do not charge credits in the following circumstances: The email verification status is “unknown” Removing a duplicate email address from your list. When you upload your list for validation, we’ll let you know if we found Activity Data for any email addresses. If you then choose to Score those email addresses, you’ll spend one additional credit for each address. Finally, Email Finder will consume twenty credits for every successful query. Similar to email validation, an “unknown” result will consume zero credits.

How many credits does the Email Finder use?

Email Finder uses the following rules for consuming ZeroBounce credits: 20 credits A format or email is provided 1 credit the domain is identified as a spam trap the domain is identified in the global suppression list the domain contains a possible typo the name parts provided are role based the domain does not have DNS entries the domain contains an unroutable IP address the domain is disposable 0 credits “Unknown” result

Which currencies can I use as payment?

ZeroBounce accepts all major currencies, including the Euro, British Pound, and Indian Rupee. You can use any currency supported by Stripe, and the checkout screen will default to your region’s currency during checkout. Please refer to our billing documentation for the complete list of accepted currencies.
