How to use Activity Data

To add Activity Data insights to your email list, please complete the following steps:

1. Upload a file for email validation using the standard method. Once the email validation process is complete, click on the purple Download button to the right.
   
2. You’ll be presented with the Data Appends toggle menu. At the bottom, you can select the checkbox for Activity Data.
   

   In the example test file pictured above, we will add Activity Data for 1 recipient when downloading the results file.

   By selecting the toggle, the Activity Data column will be added to the email validation results file. ZeroBounce’s scoring partners have matched the data and have returned the following possible results:

   

   For the date of last known activity, the result will be 1 of 7 options.

   • null (not found) and no credit deducted
   • “30” - For a match with a last activity date that is less than 30 days old
   • “60” - For a match with a last activity date that is less than 60 days old
   • “90” - For a match with a last activity date that is less than 90 days old
   • “180” - For a match with a last activity date that is less than 180 days old
   • “365” - For a match with a last activity date that is less than 365 days old
   • “365+” - For a match with a last activity date that is more than 365 days old
     Signifies a potentially old and outdated contact - not recommended for cold emailing.

   Four additional columns will also be added when Activity Data is found:

   • ZB Activity Data Count: Integer/Empty
   • ZB Activity Data Types: String (comma-separated values, sorted alphabetically)/Empty
   • ZB Activity Data Channels: String (comma-separated values, sorted alphabetically)/Empty
   • ZB Activity First Seen: String/ empty

   Once your file is downloaded, you’ll find the Activity Data enrichment columns listing the known results.
