How to Send Automatic Follow-Up Messages in Doubletick
Never let a lead go cold again. This guide walks you through building a smart follow-up system that sends a reminder only when a customer hasn't replied — and stops automatically once they do.
What you'll build
A 3-bot automation that tracks whether a customer has replied to your message and sends a follow-up if they haven't — within any time window you choose.
Before you begin: Create a custom attribute
You'll need a custom contact attribute to track reply status. Here's how to create it:
Go to Settings → Custom Contact Fields
Click Create Attribute and name it
Replied OnSet the attribute type to Text and save
Why this matters: This attribute acts like a flag. When it's set to "No", the automation knows the customer hasn't replied yet. When it's removed, the reminder flow stops.
Bot 1 — Track message delivery
This bot listens for the moment your message is delivered to the customer and immediately marks them as "not yet replied."
Bot 2 — Wait, then send the reminder
This bot watches for the attribute change made by Bot 1, waits your chosen delay, and sends a follow-up if the customer still hasn't replied.
Bot 3 — Stop reminders when the customer replies
This bot fires the moment a customer sends you a message, and clears the attribute so no more reminders are sent.
How it all works together
You send a message → Bot 1 detects delivery → sets Replied On = No
Bot 2 is triggered by the attribute change → waits your delay → sends reminder if still no reply
If the customer replies at any point → Bot 3 fires → removes the attribute → reminders stop
Pro tip: You can extend this setup to send multiple follow-ups by duplicating Bot 2 with a longer delay. Just make sure each round checks the attribute again before sending.
