# Why are my LinkedIn contact discovery tools giving me so many bounced emails and wrong numbers?
> Those tools are guessing from a profile, not reading a mailbox LinkedIn keeps. Stale jobs, pattern emails, catch-alls, and recycled phone data are the usual mess.

LinkedIn is not a contact database. A discovery or enrichment tool sees a name, a company, and sometimes a location, then it infers an email and a phone. The inference is often last year's pattern at a company the person already left.

Bounced emails are the honest failure. The mailbox is gone, the local-part was invented, or the vendor marked a catch-all as valid. Wrong numbers are quieter: a switchboard, a prior employee, a data-broker mobile that was never theirs. You still look like a stranger calling the wrong desk.

Waterfalls make this worse. Tool A misses, tool B fills a guess, tool C "verifies" a catch-all, and you send. Each hop can add a worse record. One verified source plus a small test send beats three logos on a pricing page.

People change jobs faster than most databases refresh. If the profile says Acme and the email is still at the last company, that is not a LinkedIn bug. That is a stale row. Re-check title and company the same week you send.

Do not scrape inboxes off LinkedIn to "fix" the vendor. That stacks a platform problem on a data problem. Stay on the thread if they already replied, or verify work email before the first cold send. See [how to find work emails from LinkedIn](/help/how-to-find-work-emails-from-linkedin).

## Frequently asked questions

**Is a 10 percent bounce "normal" for LinkedIn-sourced lists?**

No. That is a dirty list. Keep hard bounces under about 2 percent or stop the source. See [what is a good bounce rate](/help/what-is-a-good-cold-email-bounce-rate).

**Why is the email valid but the person is wrong?**

Valid means the mailbox exists. It does not mean it belongs to the title you found. Shared aliases and recycled addresses show up as delivered.

**Should I call every number the tool returns?**

Not until you have a reason to believe it is theirs. A wrong mobile burns the account faster than a skipped call.

**Does Omentir replace enrichment?**

Omentir is LinkedIn-first outreach. It does not magically invent a clean phone book. If you hop to email, verify that address yourself.
