Mailcut is an email verification service. Upload a list or check addresses one by one through the web app or the API to find invalid, risky and disposable addresses before you send, so fewer messages bounce and your sender reputation stays healthy. Mailcut is priced in credit packs instead of a monthly subscription: one credit verifies one email address, packs range from 5,000 to 300,000 credits, credits are valid for 12 months, and new accounts receive free credits to try the service. Free tools include an MX record lookup, an SPF, DKIM and DMARC checker, and a disposable email domain checker.
