Why teams connect Gmail and Salesloft

Keep Salesloft 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.

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.

Common use cases

  • 01 Write email and call activity back to the CRM or a Postgres table for a complete engagement timeline.
  • 02 Keep person and account custom fields populated from an enrichment pipeline for personalization tokens.
  • 03 Read Attachments and message metadata into a warehouse or document store for retention, discovery, and compliance reporting.
  • 04 Mirror Labels with pipeline or ticket states so triage done in an external tool is reflected inside the inbox.

Common sync patterns

Calls, messages, and meetings on the record

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.

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 Salesloft, so lead status reflects what actually reached the person.

One contact list, opt-outs included

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.

What you can sync between Gmail and Salesloft

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.

How changes propagate between Gmail and Salesloft

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 Salesloft 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 Salesloft 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.
  • Salesloft: Subject to the platform's per-minute API rate limits.
