What it does

This workflow makes reverse-ETL syncs reviewable. Instead of writing blindly, it computes a dry-run diff from Snowflake — how many records would be added, changed, or removed across each destination — and posts that preview to Slack with an approve control. Nothing is written until a human approves, giving you a last gate before contacts hit ad platforms and your CRM.

When to use it

Use it for sensitive or infrequent syncs where the blast radius justifies a human in the loop: list deletions, large property overwrites, or a new pipeline you do not yet trust to run unattended.

How it works

  1. 1A manual run or schedule kicks off the sync proposal.
  2. 2Compute the insert/update/delete diff against current destination state using Snowflake.
  3. 3Post the diff summary to Slack with an approve or reject control.
  4. 4A logic gate waits on the decision and stops if rejected.
  5. 5On approval, push changes to the ad destinations.
  6. 6Apply the matching changes to HubSpot and confirm completion in Slack.
