# inboxsure Discussions

InboxSure is built for anyone whose results depend on emails actually arriving — email marketers, cold-email and lead-gen teams, sales reps, and developers running signup forms. Bad addresses are expensive. Every hard bounce chips away at your sender reputation. Push your bounce rate past a few percent and Gmail, Outlook, and Yahoo start routing even your good emails to spam — or your ESP suspends the account. Purchased lists, scraped leads, and old CRM exports are full of dead mailboxes, typos, disposable inboxes, and catch-all domains you can't trust. InboxSure checks every address before you send to it.
