Connect unlimited inboxes, warm them up, send personalised sequences with follow-ups, and let an AI agent answer every reply and send your booking link.
No card needed for the trial. Works with Gmail, Google Workspace, Zoho and any IMAP/SMTP inbox.
The same system we use to run cold email for our own agencies, now as software you can use for yours.
Connect as many inboxes as you like. Sends spread across them with safe daily limits and natural gaps, so no inbox gets burned.
Your inboxes email each other and the network, get opened and replied to, and are rescued from spam automatically, building reputation every day.
Multi-step campaigns with follow-ups in the same thread, custom fields, spintax and A/B variants. Sending only inside your chosen hours.
Every reply is read and sorted (interested, question, not now, unsubscribe). Interested leads get your booking link in minutes, day or night.
See replies from all your inboxes in one place, check what the AI sent, and answer anything yourself with one click.
Built-in email checks remove bad addresses before you send, and bounces and unsubscribes are handled automatically to protect your domain.
Similar sending power for less, with the AI reply agent included in every plan. Competitor prices are their entry plans as published in 2026.

Every plan includes unlimited inboxes, warm-up, the AI reply agent and the unified inbox. Cancel any time.
Gmail and Google Workspace (with an app password), Zoho, and any provider that supports IMAP and SMTP over SSL (port 465). Outlook and Office 365 inboxes can't send from the platform yet.
When a lead replies, the agent reads it, sorts it and, if they're interested or asked a question, answers using only the offer details you give it and shares your booking link. Anything else is saved as a draft for you.
App passwords are stored encrypted in a secure vault and are only used by the sending engine. You can remove an inbox at any time.
Pick a monthly plan to keep sending. Your campaigns pause until you do; nothing is deleted.
