Never. All the credits you purchase or receive for free as part of a promotional campaign will always be available in your account. You can use them anytime you want.

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.

Our Pay as You Go option starts at $20 USD for validating 2,000 email addresses. It’s our minimum purchase. You can add on credits as you need.

Our subscriptions start at $18 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.

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

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.

Several aspects make ZeroBounce stand out. Our guaranteed 99% 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 Deliverability Toolkit, you can now verify and enhance your email list, and access all the tools you need to boost your inbox placement.

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 and score 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.

Email Finder uses the following rules for consuming ZeroBounce credits:

• 20 credits
  • If an email is verified
• 0 credits
  • “Unknown” format
