Two-way sync
Changes in Gmail or Salesloft instantly reflect in both systems. No stale data, no manual imports.
Keep Gmail and Salesloft in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Salesloft 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 Calls, Tasks, Meetings, Users in Salesloft with Threads, Labels, Drafts, Attachments 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 Salesloft. You decide which system owns which fields, and conflicts resolve by rules you set.
Activity handled in Gmail appears on the matching contact and account in Salesloft, so the next person sees the full history without leaving the CRM.
Sends, bounces, opens, and replies from Gmail update fields on the contact in Salesloft, so lead status reflects what actually reached the person.
A number, address, or unsubscribe recorded in either system updates the other, so no one calls a disconnected line or messages someone who opted out.
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 | Salesloft objects | How this pairing syncs | |
|---|---|---|---|
| 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. | Emails Sent and received email activity with engagement metadata, synced out for analytics. | Messages is specific to Gmail and Emails to Salesloft — 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. | Calls Logged call activity with dispositions and recordings metadata. | Threads is specific to Gmail and Calls to Salesloft — 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. | Tasks Rep to-dos created and completed within cadences. | Labels is specific to Gmail and Tasks to Salesloft — 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. | Meetings Booked meeting records tied to people and users. | Drafts is specific to Gmail and Meetings to Salesloft — each maps to any object or custom field on the other side. | |
| Attachments File payloads referenced by message part; read out to storage or a document system for archival and compliance workflows. | Users Seller records used for ownership mapping and activity attribution. | Attachments is specific to Gmail and Users to Salesloft — 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. | Custom Fields Per-person and per-account fields commonly populated by enrichment syncs for personalization. | History is specific to Gmail and Custom Fields to Salesloft — 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.

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. Salesloft: REST API (v2). Authentication: OAuth 2.0. Stacksync manages authentication, retries, and rate limits on both sides.
Salesloft: People and Accounts carry native CRM ID mappings, so syncs can join Salesloft engagement data to CRM records without fuzzy matching. Gmail: HistoryId cursors can expire on inactive mailboxes, requiring a full resync from messages.list. Stacksync's field mapping accounts for these differences between Gmail and Salesloft without custom code.
