Verify emails from ZoomInfo

ZoomInfo is a B2B contact database. Large database exports contain rows of very different ages. Group results by export date to see where quality drops.

Example

A sample file (fictional data)

namecompanyemaildb_statussource
Ana SilvaNorthwind Studioana@northwind.example.testhighzoominfo
Raj PatelQuill & Coraj@quill.example.testmediumzoominfo
Mei ChenLumen Goodsmei@lumen.example.testunknownzoominfo

Fictional rows. Sort by exported_on after verification.

Compare, do not replace

Keep ZoomInfo’s own status in the db_status column. After verification, download results with the original columns and compare the two row by row.

Send to valid. Review role and catchall separately. Retry unknown later because it is not billed. Remove invalid and disposable.

Where they disagree

When the tool is confident and the result is invalid, trust the newer check. When the tool is unsure and the result is valid, you have recovered a contact. We make no claim about any tool’s accuracy; measure it on your own export.

Before you collect

Check the source site’s terms for what you may collect and how you may use it, and follow the privacy and anti-spam rules that apply to your sending. ValidReach verifies addresses you already have; it does not supply contacts from any source.
