Why teams connect Gmail and Zendesk

Sync the people, users, and work records in Zendesk with the calls, messages, and events in Gmail, in real time and in both directions.

Zendesk holds the records a team works from: the contacts, the tickets or tasks, the users, and the history attached to each. Gmail moves the actual communication, whether that is a call, a text, an email, or a meeting, and every one of those is tied to a person and often to a user on your side. When the two are connected only by manual entry or a nightly export, the communication happens in one system while the record it belongs to sits in another, so people rebuild context by hand and reach out from contact lists that are already out of date.

Stacksync syncs Tickets, Tickets Comments, Users, Organizations in Zendesk with Messages, Threads, Labels, Drafts in Gmail bi-directionally and in real time. Contacts and users maintained in Zendesk feed Gmail so outbound dialing, messaging, and invites reach current numbers and addresses, and the calls, messages, and meeting events Gmail produces attach to the matching record in Zendesk within seconds. Everything is mapped field by field, with conflict resolution in place of copy-paste, and there is no middleware to build, no rate limits to babysit, and no batch job that leaves the morning running on yesterday's data.

Because the sync is field-level, each system keeps its own extras; only the shared people, users, and activity are held in agreement.

Common use cases

  • 01 Keep Zendesk users and organizations aligned with CRM contacts and accounts in both directions.
  • 02 Mirror high-priority or escalated tickets into engineering trackers through the synced database.
  • 03 Log sent and received Messages onto CRM contact and deal timelines automatically so reps never copy-paste email history.
  • 04 Create Drafts in a rep's mailbox from CRM templates and sequences, keeping sends authentic to the sender's address and signature.

Common sync patterns

One contact master

A person's number, email, or contact preferences corrected in either system update the other, so the record and the channel that reaches them stay in agreement.

Where Gmail places calls or sends messages: activity on the record

Calls, texts, emails, or meeting events from Gmail attach to the matching contact, ticket, or item in Zendesk, so the full history lives with the record instead of in a separate log.

One user and agent roster

Users kept in Zendesk map to accounts, seats, or extensions in Gmail, so the same people exist on both sides and ownership stays meaningful across the two systems.

What you can sync between Gmail and Zendesk

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 Zendesk 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 Synced with incremental and full sync per the Stacksync docs. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
History The incremental change log keyed by historyId; used for efficient delta sync so only mailbox changes since the last cursor are fetched. Ticket Forms Synced with incremental and full sync per the Stacksync docs. History is specific to Gmail and Ticket Forms to Zendesk — 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. Tickets The central work object; synced to databases for SLA and volume reporting or mirrored into engineering tools. Messages is specific to Gmail and Tickets to Zendesk — 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. Tickets Comments Synced with incremental and full sync per the Stacksync docs. Threads is specific to Gmail and Tickets Comments to Zendesk — each maps to any object or custom field on the other side.
Labels User and system labels (INBOX, SENT, custom); applied and removed via sync to mirror pipeline stages or triage states from an external system. Users End users and agents; matched to CRM contacts to keep requester data consistent. Labels is specific to Gmail and Users to Zendesk — 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. Organizations Company groupings for users; typically kept aligned with CRM accounts. Drafts is specific to Gmail and Organizations to Zendesk — each maps to any object or custom field on the other side.

How changes propagate between Gmail and Zendesk

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 Zendesk 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 Zendesk through its API, with automatic retries and rate-limit backoff.

Zendesk Gmail Sub-second propagation

DetectionZendesk notifies Stacksync of record changes through webhook events. Incremental export endpoints with cursor-based pagination, plus webhooks fired by triggers.

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.
  • Zendesk: Request limits vary by plan; incremental export endpoints have their own allowances.
