Free email verifier
Check whether an address really exists before you send. Verified against the domain's mail provider, so you know before it bounces.
20 free checks a day. No signup required.
Bounces cost more than they look
Every bounce tells mail providers your list is stale. Enough of them and your domain's reputation drops, which sends every future email to spam, including the ones to real addresses.
Checking an address here takes seconds. The verifier finds the domain's mail provider and asks it directly whether the mailbox exists.
Verifying one address at a time does not scale to a list. Enrichment in Miniloop looks up and verifies a work email for every lead you import, in one pass.
