Bulk-clean your CRM or mailing list: upload a CSV, get a verdict per address, download the clean list. Pack credits never expire.
Email lists decay — people change jobs, abandon inboxes, and domains die. A list that performed fine last year can quietly accumulate enough dead addresses to push your bounce rate into dangerous territory. ESPs notice, engagement stats lie to you, and you're paying to store and send to ghosts.
Export your list, upload the CSV, and get back every address with a verdict — valid, invalid, risky, or unknown — plus the reasons behind each call. Filter out the dead weight, re-engage or suppress the risky ones, and import a clean list back into your CRM or ESP.

Quarterly is a good cadence for active senders; before any big campaign or re-engagement push at minimum. Lists typically decay a few percent per month.
Risky usually means role accounts, catch-alls, or uncertain mailbox status. Most senders suppress them from cold campaigns but keep them for engaged, opted-in audiences.
