Two-way sync
Changes in Gmail or Smartsheet instantly reflect in both systems. No stale data, no manual imports.
Keep Gmail and Smartsheet in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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it belongs to sits in another, so people rebuild context by hand and reach out from contact lists that are already out of date.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.
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.
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.
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.
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. |
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.

Yes. Stacksync provides a managed, real-time two-way integration between Gmail and Smartsheet: authenticate both systems, choose the objects to sync (such as Gmail's Attachments and Messages), map fields visually, and changes propagate both ways in milliseconds — no code required.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for Gmail and Smartsheet: One user and agent roster; Turn a communication into follow-up work; One contact master. 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.
Gmail: Gmail API (REST, v1). Authentication: OAuth 2.0 via Google — user-authorized consent with granular scopes (gmail.readonly, gmail.modify, gmail.send, gmail.labels); restricted scopes require Google's app verification for production use. Smartsheet: REST API (v2.0). Authentication: OAuth 2.0 authorization-code flow, or a raw/personal API access token passed as a Bearer header. Stacksync manages authentication, retries, and rate limits on both sides.
Smartsheet: A sheet is capped at 500,000 cells (rows multiplied by columns), and no single cell can hold more than 4,000 characters. Gmail: Restricted Gmail scopes (reading message content) require passing Google's OAuth app verification and, for some app types, an annual third-party security assessment. Stacksync's field mapping accounts for these differences between Gmail and Smartsheet without custom code.
