# How do I check LinkedIn-sourced contact data before I email?
> Confirm they still work there, verify the mailbox, skip catch-alls, and send a 20-person test. Confidence scores from a finder are not a test.

Open the profile the same week. If title or company moved, drop the row. Enrichment that was "95 percent confident" last quarter is trivia now.

Run the address through a verifier that returns invalid, catch-all, and unknown as separate buckets. Invalid never goes out. Catch-all and unknown stay off the first blast.

Send 20 to 50 from the warmed inbox, not 2,000. Read bounce, not opens. If hard bounce is already ugly, the rest of the file is not a mystery. It is more of the same.

Spot-check phones if you call. A LinkedIn URL plus a switchboard is not a mobile. See [wrong numbers](/help/why-are-linkedin-phone-numbers-from-enrichment-wrong).

Keep a kill rule: one bad source gets removed from the waterfall, not "averaged" with a better one. Mixing junk with clean still produces junk.

## Frequently asked questions

**Is a company website contact page enough?**

For a role inbox, maybe, with low hopes. For a named person, you still want a verified personal work address or a LinkedIn thread.

**How fresh is fresh enough?**

Verify close to send, days to a few weeks, not a year-old export.

**Can I trust "catch-all but previously mailed"?**

Previously mailed is not previously delivered to a human. Test small or skip.

**Does asking on LinkedIn beat enrichment?**

Once they are talking, yes. "What's best for a calendar invite?" is cleaner than another finder.
