What Sources Are Used to Enrich Email Data?
As an added perk with ZeroBounce email verification, ZeroBounce uses third-party sources to add appended data to your emails regarding social, email domain, and geolocation factors.
ZeroBounce cannot disclose these data sources for privacy and competitive reasons but can guarantee that all provided information is reliable. In fact, the honesty and accuracy of enriched email data are demonstrated by the data appends success rate.
ZeroBounce's ability to enrich email data depends upon the availability of such information from its sources. When available, you can learn more about an email address, such as:
- The owner's name
- Gender
- Location
- The domain
- The domain age
- IP information
- Mx record information

Data appending is a free feature included with email verification but is entirely dependent on ZeroBounce's sources. If data can be retrieved, it will be included in your Overview report.
Does ZeroBounce use customer information to enrich email data?
No - ZeroBounce never uses stored or processed customer data for any of its email deliverability services or features. Any search for information occurs in real time and the retrieved data is only shared with you. All reports and files must be accessed with a unique encryption key that only you receive. Then, those files are deleted after 30 days from the platform.
To use customer data would be a significant violation of ZeroBounce's Privacy Policy.

Is enriched data included with bulk email verificationⓘ?
When possible, additional data is appended to email addresses, whether you validate a single email address or an entire list.
If your email address data is enriched with a bulk file uploaded, you can find it by reviewing your CSV results files. Additional data columns may be added to your "Valid" results file as well as to any other applicable results. You can find also find appended data to your Overview report, which can provide a top-level look at the top geographic locations for your entire list.
