Outreach ran on a paid tool like Instantly, or the team just found addresses and sent from Gmail by hand. The paid tools bill you per inbox and per seat, so the cost goes up every time you add a sending account. Doing it by hand ate hours on finding emails, spacing out the sends, tracking replies, and figuring out which inbound was a real answer versus a bounce.

It's a cold email engine that lives inside the agency dashboard, running on Next.js, Supabase, and the Gmail API. It runs multiple inboxes through OAuth with daily caps and rotation, finds and verifies prospect emails through Anymail Finder, and sends sequences of three messages on randomized gaps inside set send windows so the timing looks human. It does the follow up on its own and stops the second someone replies. Every inbound gets tagged as a reply, a bounce, or an autoresponder using a mix of rules and an LLM, and dead addresses drop out on their own. The team runs all of it from one screen.

Now adding an inbox just costs a Gmail seat, so the team can send more without the vendor bill going up every time. The send logic, the caps, and the tagging rules are ours to tune now, instead of being stuck with whatever a vendor lets us change. And nobody has to sit there running sequences and sorting inboxes by hand anymore.
