Description

Quick Overview

This workflow runs daily and weekly to manage a win-back email drip from a Google Sheets tracker, sending staged reactivation emails via SMTP after a compliance sub-workflow approves them, then updating the tracker and emailing a weekly status summary to the firm.

How it works

  1. Runs every morning at 9am and reads the “Win-Back Tracker” data from Google Sheets.
  2. Calculates which active leads are due for the next drip stage based on days since marked_cold_at and the configured WIN_BACK_DRIP_STAGES sequence.
  3. Builds a personalized, stage-specific win-back email (subject, text, and HTML) using the lead’s name and practice area.
  4. Sends the email content to a separate compliance/guardrail workflow and checks whether the message is approved or the recipient has opted out.
  5. If approved, sends the drip email via SMTP and updates Google Sheets with last_stage_sent and last_sent_at for the matching lead_id.
  6. Runs every Monday at 8am, summarizes active/reactivated/unsubscribed counts from Google Sheets, and sends the weekly summary email to the firm via SMTP.

Setup

  1. Connect Google Sheets credentials and set WIN_BACK_TRACKER_SHEET_ID to the spreadsheet that contains a “Win-Back Tracker” sheet with fields like lead_id, email, status, marked_cold_at, and last_stage_sent.
  2. Configure an SMTP email credential and set FIRM_FROM_EMAIL (sender) and FIRM_EMAIL (weekly summary recipient).
  3. Create or select a compliance/guardrail sub-workflow, set GUARDRAIL_WORKFLOW_ID, and ensure it returns an approved boolean (and handles opt-outs) for the provided email content.
  4. Set WIN_BACK_DRIP_STAGES (for example 0|check-in;14|resources;30|last-call) and adjust the stage email copy in the drip email template code if needed.
  5. Confirm the schedule trigger times (daily 9am and Monday 8am) match your timezone and operating hours.
