ZeroBounce
The deep check for an email list — ZeroBounce tests whether each mailbox actually exists before you send to it.
ZeroBounce is its own service — a paid account at zerobounce.net, run by ZeroBounce, with their login and their prices. It isn't a MockTools tool, and nothing here connects to it. This door just takes you straight there.
Open ZeroBounce →What you get in ZeroBounce
- Mailbox-level verification — checks that the mailbox itself exists, not just that the domain can take mail. That's the one check our free BounceCheck can't do.
- Risk flags on every address — catch-all, disposable, role-based (info@, support@) and toxic addresses called out before they hurt your sending reputation.
- Bulk list cleaning — upload a whole list and get it back scored, address by address, so the bad ones never get sent to.
- Pay as you go — credits or a monthly plan, bought from ZeroBounce at their prices. Nothing is charged through AgentOS.
Who it's for
Anyone about to send to a list that matters — an old book that hasn't been mailed in months, a list from somewhere else, or any send where bounces would cost you your reputation. For the quick free pass, BounceCheck on this shelf already clears out the dead domains, throwaways and duplicates.
When you tap Open ZeroBounce
- You land at zerobounce.net — in a new tab, signed out until you log in.
- You sign in with your own ZeroBounce login — MockTools never sees it, and nothing here asks for it.
- Your lists and credits are right where you left them — in your account alone.
Nothing you do in ZeroBounce shows up in AgentOS, and nothing in AgentOS is sent to ZeroBounce. The two sit side by side — this page is just the shortcut between them.
