Why teams connect Close and Gmail

Keep Close 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.

Close 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 Users, Smart Views, Leads, Contacts in Close with Attachments, History, Messages, Threads 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 Close. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Two-way sync between Close and a billing or ERP system so closed-won opportunities create customers and invoices automatically.
  • 02 Keep Close contacts aligned with a marketing automation platform so outreach lists stay current.
  • 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

Where Gmail reaches out: contacts kept current

Names, phone numbers, email addresses, and the owning rep from Close stay current in Gmail, so every call, text, or email goes to the right person at the right address.

Calls, messages, and meetings on the record

Activity handled in Gmail appears on the matching contact and account in Close, 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 Close, so lead status reflects what actually reached the person.

What you can sync between Close and Gmail

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.

Close objects Gmail objects How this pairing syncs
Custom Activities User-defined activity types with their own custom fields, mapped like standard activities. History The incremental change log keyed by historyId; used for efficient delta sync so only mailbox changes since the last cursor are fetched. Custom Activities is specific to Close and History to Gmail — each maps to any object or custom field on the other side.
Custom Fields Org-specific fields on leads, contacts, and opportunities; addressed by stable field ids in 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. Custom Fields is specific to Close and Messages to Gmail — each maps to any object or custom field on the other side.
Users Sales reps referenced as owners on leads, opportunities, and activities. Threads Conversation groupings that keep replies together; synced so a CRM timeline or support desk shows the full exchange, not isolated messages. Users is specific to Close and Threads to Gmail — each maps to any object or custom field on the other side.
Smart Views Saved lead searches that can scope which records a segment-based sync pulls. Labels User and system labels (INBOX, SENT, custom); applied and removed via sync to mirror pipeline stages or triage states from an external system. Smart Views is specific to Close and Labels to Gmail — each maps to any object or custom field on the other side.
Leads The top-level record in Close; represents a company and holds its contacts, opportunities, and activity history. Drafts Unsent messages; created and updated from templates or sequence tools so reps review before sending from their own mailbox. Leads is specific to Close and Drafts to Gmail — each maps to any object or custom field on the other side.
Contacts People nested under a lead, with emails and phone numbers used for outreach syncs. Attachments File payloads referenced by message part; read out to storage or a document system for archival and compliance workflows. Contacts is specific to Close and Attachments to Gmail — each maps to any object or custom field on the other side.

How changes propagate between Close and Gmail

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.

Close Gmail Sub-second propagation

DetectionClose notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, with polling on date_updated fields for backfills.

DeliveryEach detected change is written to Gmail through its API, with automatic retries and rate-limit backoff.

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

Rate-limit considerations

  • Close: Subject to per-endpoint rate limits communicated in response headers.
  • 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.
