Why teams connect Freshsales and Gmail

Keep Freshsales 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.

Freshsales 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 Appointments, Notes, Sales activities, Products in Freshsales 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 Freshsales. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Push product-qualified leads from the warehouse into Freshsales as contacts with lifecycle stages set.
  • 02 Keep Freshsales accounts aligned with a billing system so plan and revenue fields stay current.
  • 03 Mirror Labels with pipeline or ticket states so triage done in an external tool is reflected inside the inbox.
  • 04 Log sent and received Messages onto CRM contact and deal timelines automatically so reps never copy-paste email history.

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

What you can sync between Freshsales 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.

Freshsales objects Gmail objects How this pairing syncs
Products Catalog items attached to deals for line-level revenue data. Threads Conversation groupings that keep replies together; synced so a CRM timeline or support desk shows the full exchange, not isolated messages. Products is specific to Freshsales and Threads to Gmail — each maps to any object or custom field on the other side.
Contacts Person records carrying lifecycle stages; the main entity for two-way CRM syncs. Labels User and system labels (INBOX, SENT, custom); applied and removed via sync to mirror pipeline stages or triage states from an external system. Contacts is specific to Freshsales and Labels to Gmail — each maps to any object or custom field on the other side.
Accounts Company records kept aligned with billing, ERP, and warehouse tables. Drafts Unsent messages; created and updated from templates or sequence tools so reps review before sending from their own mailbox. Accounts is specific to Freshsales and Drafts to Gmail — each maps to any object or custom field on the other side.
Deals Pipeline records synced to a warehouse for revenue reporting. Attachments File payloads referenced by message part; read out to storage or a document system for archival and compliance workflows. Deals is specific to Freshsales and Attachments to Gmail — each maps to any object or custom field on the other side.
Tasks Rep to-dos created from external triggers or synced for productivity reporting. 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 Freshsales and History to Gmail — each maps to any object or custom field on the other side.
Appointments Scheduled meetings readable for activity analytics. 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. Appointments is specific to Freshsales and Messages to Gmail — each maps to any object or custom field on the other side.

How changes propagate between Freshsales 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.

Freshsales Gmail Sub-second propagation

DetectionFreshsales notifies Stacksync of record changes through webhook events. Polling with updated-at filters through views.

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

Rate-limit considerations

  • Freshsales: Subject to per-account API rate limits that vary by Freshworks plan.
  • 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.
