And everything around it.
Calls and LinkedIn in the same campaign
Call steps land in the rep’s dialer queue. LinkedIn invites send on their own. Other steps become tasks.
Sending that protects your domains
A 30-day send forecast, daily caps, mailbox rotation, and a whole company paused when one person replies.
Test safely first
Sandbox mode sends the real campaign to your own inboxes, so you watch replies get read.
Results you can credit
Meetings and pipeline traced to the campaign, Wren’s lessons once it ends, and which variables earned replies.
Built for teams and agencies
Reps get their own share. Full history, CSV export, and a read-only results link for clients.
Rules that keep lists clean
Suppression rules show how many people each excludes. Bad addresses fixed before launch.
