Platform
Cold email that turns into conversations
Describe your offer once. AI writes the sequence, rewrites every line per prospect and pauses the moment someone replies.
- One prompt, a full multi-step sequence
- Personalised with real prospect details
- Sender rotation across unlimited mailboxes
- Follow-ups stop automatically on reply
Saw {{company}} just opened two SDR roles, congrats. Teams scaling that fast usually fight spam folders before the first reply lands. We fix the deliverability part so your sequences get seen

- Portable SMTP and IMAP, minimum 10 slots
