Use cases

Built for teams that live in the pipeline

The same engine, shaped to how different teams actually run outbound.

Lead-generation agencies

Run outbound for every client from one login

Keep each client in its own workspace, with separate inboxes, campaigns, leads, and reporting. Switch between them in a click, and push a client's reply data straight to their CRM with webhooks.

A workspace per client, fully isolated
Unlimited sending inboxes per workspace
Per-client reply inbox and pipeline

B2B SaaS founders

Book demos before you hire an SDR

Write one sequence (or let the AI writer draft it), point it at a focused list, and let the engine work while you build product. Replies are sorted by intent, so you only step in for the ones worth your time.

AI copywriter for first drafts
A/Z test subject lines automatically
Interested replies surface to the top

Recruiters and staffing

Reach passive candidates and hiring managers

Run separate sequences for candidates and clients, each on its own schedule and tone. Conditional follow-ups chase only the people who did not reply, so nobody gets over-emailed.

Multiple sequences, multiple audiences
Conditional follow-ups by open or reply
Every conversation in one inbox

Sales teams

Scale a proven pitch without burning the domain

Rotate sends across many mailboxes, throttle volume with randomised delays, and watch per-account health so a weak inbox gets caught before it drags the others down.

Inbox rotation with per-mailbox daily caps
Per-account deliverability health score
Bounce detection that pauses bad sends

Whatever you sell, the outbound loop is the same
