Why teams connect Attio and Gmail
Keep Attio and Gmail working from the same contacts, and log every call, message, and meeting back on the record, in real time and in both directions.
Attio holds the people the business talks to: the contacts, their phone numbers and email addresses, and which rep owns the relationship. Gmail is where the talking happens, whether that is calls, texts, email, or meetings. The two depend on the same people, and when the contact list in one drifts from the other, outreach goes to stale numbers and the record of what was said never makes it back to the account.
Stacksync syncs Deals, Workspaces, Custom objects, People in Attio with History, Messages, Threads, Labels in Gmail field by field, in real time, and in both directions. Current contact details flow out to Gmail so it can reach the right person, and the calls, messages, and meetings Gmail produces flow back onto the matching record in Attio. You decide which system owns which fields, and conflicts resolve by rules you set.
Common use cases
- 01 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
- 02 Run a two-way dual-run when migrating to Attio from another CRM.
- 03 Mirror Labels with pipeline or ticket states so triage done in an external tool is reflected inside the inbox.
- 04 Log sent and received Messages onto CRM contact and deal timelines automatically so reps never copy-paste email history.
Common sync patterns
New contacts reachable right away
A contact created or updated in Attio appears in Gmail within seconds, so outreach starts without exporting a list or re-keying numbers.
Where Gmail reaches out: contacts kept current
Names, phone numbers, email addresses, and the owning rep from Attio stay current in Gmail, so every call, text, or email goes to the right person at the right address.
Calls, messages, and meetings on the record
Activity handled in Gmail appears on the matching contact and account in Attio, so the next person sees the full history without leaving the CRM.
What you can sync between Attio and Gmail
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Attio objects | Gmail objects | How this pairing syncs | |
|---|---|---|---|
| Custom objects Workspace-defined objects that behave like standard ones in the API. | Labels User and system labels (INBOX, SENT, custom); applied and removed via sync to mirror pipeline stages or triage states from an external system. | Custom objects is specific to Attio and Labels to Gmail — each maps to any object or custom field on the other side. | |
| People Standard person object; synced with marketing tools and warehouse person tables. | Drafts Unsent messages; created and updated from templates or sequence tools so reps review before sending from their own mailbox. | People is specific to Attio and Drafts to Gmail — each maps to any object or custom field on the other side. | |
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | Attachments File payloads referenced by message part; read out to storage or a document system for archival and compliance workflows. | Companies is specific to Attio and Attachments to Gmail — each maps to any object or custom field on the other side. | |
| Users Synced with incremental and full sync per the Stacksync docs. | History The incremental change log keyed by historyId; used for efficient delta sync so only mailbox changes since the last cursor are fetched. | Users is specific to Attio and History to Gmail — each maps to any object or custom field on the other side. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Messages Individual emails with headers, body, and label state; read out to a CRM or warehouse for activity logging, and sent or modified two-way from sales tools. | Deals is specific to Attio and Messages to Gmail — each maps to any object or custom field on the other side. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Threads Conversation groupings that keep replies together; synced so a CRM timeline or support desk shows the full exchange, not isolated messages. | Workspaces is specific to Attio and Threads to Gmail — each maps to any object or custom field on the other side. |
How changes propagate between Attio and Gmail
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Attio Gmail Sub-second propagation
DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.
DeliveryEach detected change is written to Gmail through its API, with automatic retries and rate-limit backoff.
Gmail Attio Sub-second propagation
DetectionGmail notifies Stacksync of record changes through webhook events. Incremental sync via users.history.list from a stored historyId cursor, plus real-time push notifications through Google Cloud Pub/Sub watch on the.
DeliveryEach detected change is written to Attio through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Attio: Subject to the platform's published API rate limits.
- Gmail: Quota is measured in units per user per second (e.g. messages.list = 5 units, messages.send = 100 units) against a 250 quota-unit/user/second limit and a daily project cap; exceeding limits returns 429 with exponential backoff expected.
