Why teams connect Gmail and Smartsheet

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

Smartsheet 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it belongs to sits in another, so people rebuild context by hand and reach out from contact lists that are already out of date.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 Reports, Attachments, Discussions and Comments, Users and Groups in Smartsheet with History, Messages, Threads, Labels in Gmail bi-directionally and in real time. Contacts and users maintained in Smartsheet 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 Smartsheet 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 Trigger downstream actions in an operational database when a Row's status Cell changes, using sheet webhooks for near-real-time updates.
  • 02 Two-way sync a project-tracker Sheet's Rows with a Postgres table so engineering works in SQL while project managers stay in Smartsheet.
  • 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

One user and agent roster

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

Turn a communication into follow-up work

A completed call, an inbound message, or a delivery result in Gmail can create or update a ticket, task, or record in Smartsheet, so nothing that happens on a call or in a thread gets dropped.

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.

What you can sync between Gmail and Smartsheet

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 Smartsheet 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 rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
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. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Messages is specific to Gmail and Rows to Smartsheet — 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. Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Threads is specific to Gmail and Columns to Smartsheet — 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. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. Labels is specific to Gmail and Cells to Smartsheet — 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. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. Drafts is specific to Gmail and Reports to Smartsheet — 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. Discussions and Comments Threaded comments on rows and sheets; read out to sync collaboration history or activity into another system. History is specific to Gmail and Discussions and Comments to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between Gmail and Smartsheet

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

Smartsheet Gmail Sub-second propagation

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.
  • Smartsheet: 300 requests per minute per access token; heavy calls like posting attachments cost 10x (30/min). A 429 returns errorCode 4003, back off ~60s.
