Why teams connect Gmail and Twenty CRM

Keep Twenty CRM 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.

Twenty CRM 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 Attachments, Workspace Members, People, Companies in Twenty CRM with Messages, Threads, Labels, Drafts 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 Twenty CRM. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Mirror support tickets or tasks between Twenty and an operations tool.
  • 02 Run a continuous sync from a legacy CRM into Twenty during a migration so both systems stay usable through cutover.
  • 03 Create Drafts in a rep's mailbox from CRM templates and sequences, keeping sends authentic to the sender's address and signature.
  • 04 Read Attachments and message metadata into a warehouse or document store for retention, discovery, and compliance reporting.

Common sync patterns

Where Gmail reaches out: contacts kept current

Names, phone numbers, email addresses, and the owning rep from Twenty CRM 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 Twenty CRM, so the next person sees the full history without leaving the CRM.

Where Gmail sends at scale: delivery and reply status back on the contact

Sends, bounces, opens, and replies from Gmail update fields on the contact in Twenty CRM, so lead status reflects what actually reached the person.

What you can sync between Gmail and Twenty CRM

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.

Gmail objects Twenty CRM objects How this pairing syncs
Attachments File payloads referenced by message part; read out to storage or a document system for archival and compliance workflows. Attachments Files linked to records. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Labels User and system labels (INBOX, SENT, custom); applied and removed via sync to mirror pipeline stages or triage states from an external system. Companies Account-level records that group people and opportunities. Labels is specific to Gmail and Companies to Twenty CRM — each maps to any object or custom field on the other side.
Drafts Unsent messages; created and updated from templates or sequence tools so reps review before sending from their own mailbox. Opportunities Deal records tracked through pipeline stages, synced for forecasting. Drafts is specific to Gmail and Opportunities to Twenty CRM — each maps to any object or custom field on the other side.
History The incremental change log keyed by historyId; used for efficient delta sync so only mailbox changes since the last cursor are fetched. Tasks To-dos linked to people, companies, or deals. History is specific to Gmail and Tasks to Twenty CRM — each maps to any object or custom field on the other side.
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. Notes Free-form notes attached to records, useful for mirroring activity from other tools. Messages is specific to Gmail and Notes to Twenty CRM — each maps to any object or custom field on the other side.
Threads Conversation groupings that keep replies together; synced so a CRM timeline or support desk shows the full exchange, not isolated messages. Custom Objects User-defined objects created in Twenty's data model settings, addressable through the same APIs as standard objects. Threads is specific to Gmail and Custom Objects to Twenty CRM — each maps to any object or custom field on the other side.

How changes propagate between Gmail and Twenty CRM

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.

Gmail Twenty CRM 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 Twenty CRM through its API, with automatic retries and rate-limit backoff.

Twenty CRM Gmail Sub-second propagation

DetectionTwenty CRM notifies Stacksync of record changes through webhook events. Webhooks on record create, update, and delete events, or polling on record update timestamps.

DeliveryEach detected change is written to Gmail through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • 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.
  • Twenty CRM: Subject to the platform's API rate limits; self-hosted deployments control their own limits.
