Why did LeadMagic find fewer emails than usual?
The LeadMagic help pages give 3 common reasons. The first to rule out: Running a list through validation only checks the addresses already there, so it can show no new emails found.
What causes it?
Running a list through validation only checks the addresses already there, so it can show no new emails found.
In the LeadMagic help:
Email Validation only validates: it won't find new emails
Low Match Rates: LeadMagic Help, read 2026-11-12.A finished job can still hold failed rows, so the number of emails found can be lower than the rows in the list.
In the LeadMagic help:
A job can show Complete with some failed rows.
Job and Upload Errors: LeadMagic Help, read 2026-11-12.A not found result means LeadMagic could not locate a work email it was sure of for that contact, so more of these lowers the found count.
In the LeadMagic help:
not_found means LeadMagic couldn't locate a verified work email for that contact.
Email Finder: No Results: LeadMagic Help, read 2026-11-12.
How do I check it myself?
Compare the number of failed rows with the total rows in the job.
In the LeadMagic help:
Check the failed row count against total rows.
Job and Upload Errors: LeadMagic Help, read 2026-11-12.Look at the run history for a list to see each run and the errors it hit.
In the LeadMagic help:
Open History in the table's tool panel to see each run and its errors.

How does LeadMagic work with Feder?
- Connect LeadMagic to Feder and it joins your Interest apps.
- When you connect LeadMagic, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See whether you can trust the numbers in LeadMagic, one of your Interest apps. Feder only reads. It never changes anything in LeadMagic.
