Why teams connect Gmail and Insightly

Keep Insightly 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.

Insightly 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 Notes, Products, Custom Fields, Contacts in Insightly 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 Insightly. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Write product usage or billing data from internal databases into Insightly custom fields for account context
  • 02 Deduplicate and align customer records between Insightly and an ERP or invoicing system
  • 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 reaches out: contacts kept current

Names, phone numbers, email addresses, and the owning rep from Insightly 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 Insightly, 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 Insightly, so lead status reflects what actually reached the person.

What you can sync between Gmail and Insightly

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 Insightly objects How this pairing syncs
Threads Conversation groupings that keep replies together; synced so a CRM timeline or support desk shows the full exchange, not isolated messages. Products Product catalog entries support line-item syncing on opportunities and quotes. Threads is specific to Gmail and Products to Insightly — 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. Custom Fields Per-object custom fields carry enrichment and billing data written from external systems. Labels is specific to Gmail and Custom Fields to Insightly — 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. Contacts Person records sync with marketing and support tools to keep one contact list. Drafts is specific to Gmail and Contacts to Insightly — 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. Organizations Company records map to accounts in ERPs and other CRMs. Attachments is specific to Gmail and Organizations to Insightly — 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. Leads Unqualified prospects sync in from forms and enrichment sources before conversion. History is specific to Gmail and Leads to Insightly — each maps to any object or custom field on the other side.
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. Opportunities Pipeline records feed forecasting and warehouse-based reporting. Messages is specific to Gmail and Opportunities to Insightly — each maps to any object or custom field on the other side.

How changes propagate between Gmail and Insightly

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

Insightly Gmail Interval-based propagation

DetectionStacksync polls Insightly for changes on an incremental schedule, reading only records changed since the previous pass. Polling on record updated-date fields.

DeliveryEach detected change is written to Gmail 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.
  • Insightly: Daily API request caps vary by Insightly plan.
