Email every new signup yourself

Every new signup gets a note from you.

Three lines about them, ready each weekday morning.

Download RiverHow to start

How it works.

Each weekday River finds who signed up, looks each person up and drafts a short note from you offering to set them up together, with a booking page for the call.

  1. Choose your offer

    Fifteen minutes to set it up together, or just one question.

  2. River looks up each person

    Company, role and team size, plus what they’ve already done in your product.

  3. One card each morning

    Who signed up, a line about each, and the note written for them.

What you get.

  • A three-line note from your Gmail to each new signup, every weekday
  • A booking page for setup calls, made by River with nothing to connect
  • A Signups Sheet showing who replied, who booked and what they need

A few things to know.

Where does River find new signups?

In your product’s own sign-up list, signup emails in Gmail and new trials in Stripe. It asks only if it finds none.

Does it email people on its own?

No. The day’s notes go out when you say yes to that morning’s card, and only to the people on it.

What does it cost?

It uses your plan’s AI credit, like everything else in River. Notes go from your own Gmail in plain text, as if you typed them.
