Why teams connect Folk CRM and Gmail

Keep Folk CRM 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.

Folk CRM 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 Companies, Groups, Custom fields, Notes in Folk CRM with Messages, Threads, Labels, Drafts 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 Folk CRM. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Keep folk and a billing or customer success tool aligned on company records as deals close.
  • 02 Sync folk people and companies with a marketing or outbound tool so outreach lists stay current.
  • 03 Create Drafts in a rep's mailbox from CRM templates and sequences, keeping sends authentic to the sender's address and signature.
  • 04 Read Attachments and message metadata into a warehouse or document store for retention, discovery, and compliance reporting.

Common sync patterns

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 Folk CRM, 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.

New contacts reachable right away

A contact created or updated in Folk CRM appears in Gmail within seconds, so outreach starts without exporting a list or re-keying numbers.

What you can sync between Folk CRM 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.

Folk CRM objects Gmail objects How this pairing syncs
Notes Free-text context attached to people and companies, readable for reporting. History The incremental change log keyed by historyId; used for efficient delta sync so only mailbox changes since the last cursor are fetched. Notes is specific to Folk CRM and History to Gmail — each maps to any object or custom field on the other side.
Reminders Follow-up items that can be created from external triggers. 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. Reminders is specific to Folk CRM and Messages to Gmail — each maps to any object or custom field on the other side.
People Contact records; the primary entity synced with outreach and enrichment tools. Threads Conversation groupings that keep replies together; synced so a CRM timeline or support desk shows the full exchange, not isolated messages. People is specific to Folk CRM and Threads to Gmail — each maps to any object or custom field on the other side.
Companies Organization records linked to people and kept aligned with billing or CS systems. Labels User and system labels (INBOX, SENT, custom); applied and removed via sync to mirror pipeline stages or triage states from an external system. Companies is specific to Folk CRM and Labels to Gmail — each maps to any object or custom field on the other side.
Groups Shared workspaces that organize contacts; group membership is often the field integrations act on. Drafts Unsent messages; created and updated from templates or sequence tools so reps review before sending from their own mailbox. Groups is specific to Folk CRM and Drafts to Gmail — each maps to any object or custom field on the other side.
Custom fields Group-scoped attributes that receive enriched or computed values from external systems. Attachments File payloads referenced by message part; read out to storage or a document system for archival and compliance workflows. Custom fields is specific to Folk CRM and Attachments to Gmail — each maps to any object or custom field on the other side.

How changes propagate between Folk CRM 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.

Folk CRM Gmail Sub-second propagation

DetectionFolk CRM notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, with polling of list endpoints as a fallback.

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

Gmail Folk CRM Sub-second propagation

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

Rate-limit considerations

  • Folk CRM: Subject to the platform's API rate limits.
  • 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.
