Enrichley validates email addresses, and it is unusually good at the hard case: catch-all domains that accept everything and tell you nothing. Running a list through it before outreach protects a sending reputation that takes months to rebuild.
Enrichley is the gate. Everything enrichment produced passes through it on the way to a sequencer.

- “Validate this list before the Instantly campaign goes out”
- “Drop anything undeliverable from these 300, then load the rest into SmartLead”
- “Is this address safe to send to?”

What your agent reads before it touches Enrichley
