BulkMailCheck is an email verification and list-cleaning service that checks addresses with real SMTP mailbox tests, flags catch-all and disposable domains, and reports honest Unknown results instead of guessing. It also offers a bulk list cleaner for CSV/TXT/TSV files up to 150,000 addresses, an email finder, and a set of 43 free deliverability tools covering SPF, DKIM, DMARC, BIMI, MTA-STS, blocklists and DNS. A REST API lets developers verify addresses and clean lists programmatically.
