Promised follow-ups

Follow up on what you promised a customer

Keep the reminder with the email where you made the promise. In Inbox Works, write “I’ll send it on Friday”, and the email comes back to the Inbox on Friday with that sentence.

How it works

When your reply includes a promise with a specific day, such as “I’ll send it on Friday”, the email comes back to the Inbox that day.

The toast after Send says the follow-up is set, with Undo.

It comes back with the sentence you wrote, so you see what you promised.

Why it happens

  • The reply is sent, the work isn’t.1

    After you reply, the email looks handled, though you still owe the customer something.

  • The person who promised is away.2

    If the teammate who made a promise is away, someone else may need to check what is due.

Limits and sources

Limits

  • Follow up looks for a promise with a day in your reply. A vague one, such as “soon”, sets nothing.
  • It brings the email back. It never writes to the customer.
  • You can also set one by hand on an email you’ve replied to: Follow up in its header, or F.
  • Google Workspace, in early access by approval: forward your shared address to Inbox Works, and replies go out from your own Google account. Microsoft 365, in early access by approval: sign in once to connect your shared address, and replies go out from it.

Questions

How do I cancel a follow-up?

Open Follow up in the email’s header and choose Don’t follow up, or press Undo in the toast after Send.

Can we use it with our own email now?

On Google Workspace and Microsoft 365, yes, by approval: early access is open, so ask for it and we write when your team can start. The demo, with sample email, is open now.
