Email verification

Also called: Email validation, List cleaning

Email verification checks whether an address can receive email before you send to it: that it is well formed, that its domain has a mail server, and ideally that the mailbox exists.

How it affects cold email

Verification is the cheapest way to keep your bounce rate down. Re-verify lists before reusing them: people change jobs and addresses stop working.

How Inboxed handles it

  • Every lead you add to a campaign is verified free and without limit: format, known disposable domains, role addresses like info@, common typos (it suggests gmail.com for gmial.com) and a live MX lookup. Invalid, disposable and role addresses are removed before the campaign is priced, so you never pay for them.
  • Confirming that a mailbox exists and scoring catch-all domains needs a verification provider connected with your own account. The free email verifier checks single addresses or a CSV.
