Quick Start Guide:

Email Verification Service

What the Service Does:

Datazapp provides labels indicating the deliver-ability / existence of inputted Email addresses, labeling each Email as Verified (deliverable), Failed (hard-bounce), or Accept-All.

Step #1 - File

You'll need a spreadsheet or txt file.

This can be a .csv, Excel file, or text (.xlsx or .xls or .txt)

Step #2 - Format

Ensure your list has 1 column containing Email addresses.

Please limit 1 email address per cell in your email column. Multiple emails per cell won’t be accepted.

13. . .[email protected]. . .. . .Failed
14. . .[email protected]. . .. . .Verified
15. . .[email protected]. . .. . .Failed

Interpreting the Results:

Use the key below to interpret the labels for phone type & DoNotCall status.

  • Verified = Confirmed as a deliverable Email address
  • Failed = Hard Bounce, not a deliverable Email address
  • Accept-All = Email's domain settings "accept all" messages to the domain, making it impossible to confirm address exists
  • Unknown = Unknown address deliverability
