Bulk Email Verify
Bulk Email Verifier
Paste up to 20 emails and verify syntax, MX records, disposable domains, free providers, and role accounts in one run. Clean a short list before outreach—without SMTP probes or mailbox guessing.
Up to 20 unique emails (0 parsed). No SMTP probes.
Short lists still hide bounce risk
Even a 20-row sheet from a Maps scrape can mix typos, disposable domains, and dead MX. Manually eyeballing each cell does not scale. A bulk email verifier with a hard cap keeps free checks honest while still clearing the worst rows before you sequence.
How bulk verification should work
Paste one email per line (or comma-separated), stay within the 20-address cap, complete Turnstile, and read a table of hygiene flags. Export CSV when you want the results in a sheet.
Cap at 20 for free use
Keeps DNS load reasonable and encourages focused QA on priority lists rather than dumping entire CRMs.
Same signals as single verify
Syntax, MX, disposable, free, and role—aligned with the single email verifier so policies stay consistent.
CSV for ops handoff
Download results to filter in Sheets or merge back into your lead file.
From bulk flags to outreach
Use bulk verify after a scrape sample or before a small campaign. For published contacts you still lack, pair with Website Email Peek or paid Lead Scraper enrichment.
Drop no-MX and bad syntax
Remove addresses that cannot receive mail before sending.
Filter disposable & free
Apply your B2B policy to throwaway and consumer domains.
Hand off clean rows
Export CSV and continue into sequences or enrichment.
Bulk verify without overclaiming
A green MX flag is not an inbox guarantee. Large providers and catch-alls will look valid.
No SMTP
We do not open port 25, so mailbox existence is never claimed.
Deduped input
Duplicate lines are skipped; only the first 20 unique addresses are checked.
Need one address?
Use the single Email Verifier for typo suggestions on a lone address.
