Why teams connect Copper CRM and Gmail

Keep Copper 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.

Copper 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 Opportunities, Activities, Tasks, Projects in Copper CRM 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 Copper CRM. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Two-way sync between Copper and an accounting or invoicing system so won opportunities become customers and invoices.
  • 02 Keep Copper contact data aligned with a marketing automation tool so Gmail-sourced contacts enter nurture flows.
  • 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

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 Copper CRM appears in Gmail within seconds, so outreach starts without exporting a list or re-keying numbers.

Where Gmail reaches out: contacts kept current

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

What you can sync between Copper 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.

Copper CRM objects Gmail objects How this pairing syncs
Leads Unqualified prospects kept separate from People until converted. Labels User and system labels (INBOX, SENT, custom); applied and removed via sync to mirror pipeline stages or triage states from an external system. Leads is specific to Copper CRM and Labels to Gmail — each maps to any object or custom field on the other side.
Opportunities Deals tracked through pipelines and stages; synced for revenue reporting. Drafts Unsent messages; created and updated from templates or sequence tools so reps review before sending from their own mailbox. Opportunities is specific to Copper CRM and Drafts to Gmail — each maps to any object or custom field on the other side.
Activities Logged emails, calls, meetings, and notes attached to records. Attachments File payloads referenced by message part; read out to storage or a document system for archival and compliance workflows. Activities is specific to Copper CRM and Attachments to Gmail — each maps to any object or custom field on the other side.
Tasks To-dos with due dates and assignees, usable in workload syncs. History The incremental change log keyed by historyId; used for efficient delta sync so only mailbox changes since the last cursor are fetched. Tasks is specific to Copper CRM and History to Gmail — each maps to any object or custom field on the other side.
Projects Post-sale work records Copper offers alongside classic CRM objects. 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. Projects is specific to Copper CRM and Messages to Gmail — each maps to any object or custom field on the other side.
Pipelines Stage definitions that give opportunity records their stage context. Threads Conversation groupings that keep replies together; synced so a CRM timeline or support desk shows the full exchange, not isolated messages. Pipelines is specific to Copper CRM and Threads to Gmail — each maps to any object or custom field on the other side.

How changes propagate between Copper 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.

Copper CRM Gmail Sub-second propagation

DetectionCopper CRM notifies Stacksync of record changes through webhook events. Webhook subscriptions for record create/update/delete events.

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

Rate-limit considerations

  • Copper 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.
