How to send automatic follow-up emails in Gmail when someone doesn't reply
Gmail will sometimes tell you to follow up. It won't do it for you. Nudges bring an old sent email back to the top of your inbox with a prompt, but you still have to write the follow-up and send it, and Gmail only nudges on emails it picks.
This guide shows how to turn nudges on if a prompt is all you need, and how to set a follow-up that sends automatically from your Gmail account, arrives as a reply in the same thread, and cancels itself if the person answers first.
Before you start
- Gmail or Google Workspace in Google Chrome (other Chromium browsers are untested)
- The Outsolvi Chrome extension installed, for follow-ups that send automatically
- Your Gmail account connected to Outsolvi, so it can send the follow-up from your mailbox and see replies
Step-by-step
- 1
Turn on nudges if a prompt is enough
In Gmail on a computer, open Settings, go to the General tab, find Nudges and check Suggest emails to follow up on. Gmail will then surface some sent emails at the top of your inbox. It suggests; it never sends.
- 2
Send the original email with tracking on
Send your email from Gmail with the Outsolvi extension tracking it. The follow-up attaches to that tracked email, so it replies in the right thread and knows which reply should cancel it.
- 3
Open the sent email and choose Schedule follow-up
Open the email from Sent, find the Outsolvi panel on the message, and select Schedule follow-up. The follow-up form opens right there in Gmail.
- 4
Write the follow-up
Add a subject and a message. Give them a simple reason to reply, like one question or a proposed time. Short follow-ups that ask for one thing get answered more often than long recaps.
- 5
Pick when it sends
Under Send after, choose 1 day, 3 days, 1 week or 2 weeks after the original email.
- 6
Choose Auto-send or a prompt
Auto-send (recommended) sends it for you when it's due. Notify me to send manually prompts you instead, if you'd rather check it before it goes.
- 7
Let it stop on reply
If they reply before the follow-up is due, Outsolvi cancels the remaining follow-ups for that email, so you don't chase someone who has already answered.
Set up tracking in 2 minutes instead of 20.
Outsolvi installs as a native Outlook add-in or Gmail Chrome extension. Every open is graded, hot leads get flagged in the web app, and Write with AI drafts your follow-ups there too. From $7/mo, 14-day free trial.
Troubleshooting
There's no Schedule follow-up option on the email
It appears on emails sent with Outsolvi tracking. Emails sent before the extension was installed, or from a browser where it isn't running, have no tracked thread to reply into.
Nudges setting is missing
Check the General tab in Settings on a computer; on the iPhone and iPad app it's under Settings, Inbox customizations, Nudges. If you still don't see it, your Workspace admin or account type may not offer it.
The follow-up still sent after they replied
Check whether they wrote back in a new email instead of replying to yours, or from another address. A reply outside the thread may not be matched to the original, so the follow-up can still go out.
Frequently asked
Does Gmail have automatic follow-ups?
No. Nudges suggest sent emails you may need to follow up on, and schedule send can send a message later, but Gmail has nothing that sends a follow-up because someone didn't reply.
Does the follow-up come from my Gmail account?
Yes. Outsolvi sends it through your connected Gmail or Google Workspace account as a reply in the same thread, so it looks like you sent it by hand. During a trial it ends with a short "Sent with Outsolvi" line.
What does connecting my Gmail account give Outsolvi?
The ability to send follow-ups from your account and to see replies so it can stop them. That sync includes recent mail, content included, stored encrypted at rest. The follow-ups you write are stored too, so they can be sent later.
Can I check a follow-up before it sends?
Yes. Choose Notify me to send manually and Outsolvi prompts you when it's due instead of sending it.
