Recover abandoned onboarding users with personalized emails via Postgres, Gmail & Slack

How it works

This workflow automatically identifies users who started but did not complete the signup process. It runs on a fixed schedule, checks your database for inactive and incomplete users, and validates the results before proceeding. Each user is then processed individually to send a personalized recovery email and enroll them in a follow-up sequence. Finally, the workflow updates the database to avoid duplicate outreach and notifies the sales team in Slack.

Step-by-step

• Step 1: Run scheduled check and identify abandoned users

  • Schedule Trigger – Executes the workflow automatically every 24 hours.
  • Find Abandoned Users – Queries Postgres for users marked as incomplete and inactive for over 24 hours.
  • If – Confirms that valid user records exist before continuing.

• Step 2: Process users and send recovery emails

  • Loop Over Items – Processes users one at a time to avoid rate limits and execution errors.
  • PrepareEmail email – Generates a personalized recovery email using a predefined template.
  • Send a message – Sends the recovery email through Gmail.
  • Get a message – Retrieves the sent email details for tracking and thread reference.
  • StartSequence email – Adds the email to a follow-up sequence for engagement tracking.

• Step 3: Update records and notify the team

  • Update rows in a table – Marks the user as contacted to prevent duplicate recovery emails.
  • Alert Sales Team – Sends a Slack notification with user details and recovery status.
