What is he doing?

This automated Follow-Up agent tracks communication with customers or prospects and automatically sends a series of reminder emails at set intervals. If the customer responds or has a calendar appointment – automatically stops follow-up messages.

Suitable for sales teams, agencies, HR departments and marketing campaigns, who want to automate email follow-up and avoid missed opportunities.

How does it work?

Schedule Trigger

Activated daily or weekly to check the customer list in Google Sheets.

Get rows in Google Sheets

Extracts the emails and data of customers who need to receive a follow-up message.

Gmail - Send an initial email

The agent sends the first email in the series (for example, an offer, invitation, or reminder).

Wait Nodes

The workflow waits for a preset period – for example, 3 days – before checking for a response.

Gmail - Check for response

The system checks the inbox for emails from the same contact.

Google Calendar – Check for an appointment

If the customer has scheduled an appointment (or has an event associated with it), the agent marks the communication as closed and stops further emails.

If no response → Send another follow-up

Conditional logic (If / Switch nodes)

Controls the process – if there is a response → workflow ends; if not → continues with a new wait and next letter.
