Verify emails from Cognism

Cognism is a B2B contact data provider. When a provider’s records are exported in volume, the share of invalid and catchall results on your own sample is the number that matters for your send.

Example

A sample file (fictional data)

namecompanyemailprovider_statussource
Ana SilvaNorthwind Studioana@northwind.example.testhighcognism
Raj PatelQuill & Coraj@quill.example.testmediumcognism
Mei ChenLumen Goodsmei@lumen.example.testunknowncognism

Fictional rows. Verify a 200-row sample before committing to a full export.

Compare, do not replace

Keep Cognism’s own status in the provider_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.
