Questions to ask any lead generation company before you outsource, from data accuracy to reporting and trials.

2026-10-01 · 4 min read

Outsourcing lead generation can save time, but only if the provider is transparent about quality.

Ask how data is verified

A reliable provider can explain how emails, phones and titles are checked.

Ask for a sample batch

Reviewing a small sample lets you judge accuracy and fit before committing.

Check the tools and process

Look for experience with platforms like LinkedIn Sales Navigator, Apollo and ZoomInfo, plus a clear workflow.

Be wary of guarantees

No honest provider can guarantee sales. Look for clear scope, reporting and communication instead.
