Let agents clean every email list with Mails.so
QX validates addresses, flags risky contacts and rebuilds your outreach lists automatically—so your team protects sender reputation instead of babysitting CSV files.
Stop blowing up deliverability with stale lists, typo'd addresses, and unchecked imports. Let an agent verify every one.
Always-clean outreach lists
Agents run every new list through Mails.so before a single email goes out—dropping invalid, disposable and catch-all addresses so bounce rates stay low and inboxes stay open.
Verify the moment it's typed
New signups, form fills and CRM contacts get validated on the fly—blocking typos and burner emails at the door so you never chase a contact that doesn't exist.
Protect your sender score
Agents continuously re-check active contacts, retire addresses that decay, and quarantine risky domains—so your sending reputation stays healthy and campaigns keep landing in primary inboxes.
