ListCheckup is an email verification service. You upload your mailing list, we check every address against its mail server, and you get a clear verdict for each one — valid, invalid, risky, or unknown — so you send to people who exist and stop paying for bounces.Bad addresses pile up in every list. People mistype their email, abandon old inboxes, or leave companies, and every dead address you keep mailing hurts your sender reputation and pushes your real messages toward the spam folder. Cleaning your list before a campaign is the cheapest fix in email marketing, and that is the one job we do.We work on a pay-as-you-go basis: you buy credits when you need them, there is no subscription, nothing renews, and credits never expire. Getting started is free — every account gets 100 free verifications, refilled each month, with no card required. And you are never charged for a maybe: if we cannot reach a definitive answer about an address, that check costs nothing.Your lists stay yours. We never sell or share addresses, uploads are deleted according to your retention setting, and you can erase everything yourself at any time. When you need help, a real person answers — by email or WhatsApp.ListCheckup is built for shop owners, newsletter writers, and anyone who sends email to a list and wants it to actually arrive.
