Overview
Never pay twice for data. Every list you upload is checked against the exclusion list; unique emails are added automatically, and anything blacklisted or low-value is filtered out.
Quick Links
Check & Verify
Upload bought lists. Unique emails are added automatically so you never pay for the same data twice — and anything on the blacklist is filtered out.
Step 1 verifies all unique emails. Each later step re-verifies the catch-all results from the step before it. Valid emails found at any step are kept. Cost: ~1 verification credit per email checked, per step.

Provider links
Generate a private link a lead provider can use to check their files against our list — without ever seeing our emails. Every check is logged below.

Exclusion List
Export
Upload the full exclusion list to Google Drive and get a shareable link (readable by anyone at renaissancegrowth.io). Large export — it streams straight to Drive.
Look up an email
Check whether a single address is already in our list or on a blacklisted / no-buy domain.
Bulk Check
Paste up to a few thousand emails (one per line or comma-separated) to instantly see which are already excluded — no file needed.
Blacklist
Emails and domains we never contact — opt-outs and do-not-email. Synced automatically every day from the blacklist sheet.
Blacklisted domains
Any email at these domains is filtered out. Add or remove manually here.
Settings
"Don't buy" domains
Personal/free + enterprise/brand domains we never pay for. Net-new emails at these domains are flagged "Don't buy" and not added.

Verifier Agreement Test
Paste a sample of emails and run them through two verifiers to see how often they agree — useful for deciding which to standardize on. Uses ~1 credit per email on each verifier.
