Overview
OutboundSync gets your outbound activity into Attio. Every send, reply, open, click, connection accept, and call from your sales engagement platforms gets logged on the right Attio record, in real time.
No BCC logging. No CSV exports. No brittle no-code tooling. Just a CRM that finally reflects what your outbound team is actually doing.
Built for agencies and GTM teams running multi-channel outbound at scale. Trusted since 2023 by hundreds of teams around the world to sync hundreds of millions of outbound activities.
OutboundSync customers include GTM leaders like Zapier, Redis, Windsurf, Sendoso, Gainsight, Tapcheck, David Protein, Factorial, Stocktwits, Bluecore, Gym Launch, VSCO, and many more.
If your team runs outbound, OutboundSync makes sure Attio knows what happened across email, social, and other channels.
How it works
Connect your sales engagement platforms once. OutboundSync receives activity in near real-time, deduplicates against your Attio workspace, and writes events and enriched fields to the right records.
What syncs
Email activity: Sends, opens, clicks, replies, bounces, and unsubscribes from Smartlead, Instantly, EmailBison, Mixmax, SuperSend, Lemlist, Reply, Salesforge, GetSales, SalesRobot, Brevo, HotHawk, and Masterinbox.
Social activity: Connection requests, accepts, messages, replies, profile views, post engagement, and sequence steps from HeyReach, Aimfox, Drippi, SalesRobot, Lemlist, Reply, Salesforge, GetSales, HotHawk, and Masterinbox.
Key features
- Objects created and matched by email or social profile URL, with no duplicates.

Configure
Set up with guided onboarding from our team.
- Connect Attio. Sign up at outboundsync.com and authorize your Attio workspace via OAuth.
- Connect your sales engagement platform. Create a webhook receiver in OutboundSync, then add that webhook URL in your sales engagement platform’s webhook settings.
- Add an API connection if needed. Some platforms require an API key so OutboundSync can fetch event details or apply filters before syncing it into Attio.
- Configure the sync. Choose which outbound data should sync into Attio, such as all supported events or selected categories like interested replies only. Select how records should be matched to Attio people and companies, and optionally forward outbound events to additional endpoints.
- Test the sync. Send a manual test payload to confirm how OutboundSync will match the record and write activity into Attio.
Every user gets individual onboarding from our team, and every plan includes every feature.
