Privacy policy

Last updated 6 November 2026

Email Engagement Sync is made by Support Labs (www.supportlabs.co.uk), a UK business. This page explains what the app does with data from your Attio workspace and your email tool (MailerLite or Brevo). Contact: support@supportlabs.co.uk.

What we access

With your permission, the app reads and writes People in your Attio workspace (email address, first name, last name, company and the six email attributes it adds), adds notes when you turn that on, and receives change notices from Attio. In your email tool it reads and writes subscribers, groups or lists, and receives opens, clicks, unsubscribes, bounces and spam reports.

What we store

  • Your Attio access token and your email tool API key, encrypted with AES-256-GCM.
  • For each person: a one-way salted hash of their email address, their Attio record id, short fingerprints of the synced fields (so the sync does not loop) and engagement totals (opens, clicks, last opened, last clicked, status, last campaign).
  • An activity log with masked email addresses (for example s***@example.com), kept to the last 1,000 lines.
  • Your settings, and your plan and Stripe customer id.

We do not keep copies of names or full email addresses, and we do not sell, share or use your data for anything other than running the sync.

Who processes it

Cloudflare (hosting and database, EU and US data centres) and Stripe (payments; card details go straight to Stripe and never reach us). Data passes between Attio and your email tool only as you configure it.

Your contacts' rights

You are the controller of your contacts' data; we process it on your behalf to run the sync. The app never re-subscribes anyone who unsubscribed. Only send people who have agreed to hear from you.

Deleting your data

Press "Disconnect and delete my data" in the app, or uninstall it from Attio and email us. Disconnecting removes our webhooks and deletes everything we hold for your workspace straight away. Payment records stay with Stripe as the law requires.

Changes

If this policy changes we will update the date above and tell connected workspaces in the app.
