Why teams connect Gmail and Zoho SalesIQ

Keep Zoho SalesIQ 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.

Zoho SalesIQ 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 Visitors, Conversations, Contacts (People), Companies in Zoho SalesIQ 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 Zoho SalesIQ. You decide which system owns which fields, and conflicts resolve by rules you set.

Common use cases

  • 01 Mirror conversation and operator metrics to a warehouse for support and sales analytics.
  • 02 Sync SalesIQ conversations and visitor details into a CRM so reps see chat history on the contact record.
  • 03 Read Attachments and message metadata into a warehouse or document store for retention, discovery, and compliance reporting.
  • 04 Mirror Labels with pipeline or ticket states so triage done in an external tool is reflected inside the inbox.

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 Zoho SalesIQ 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 Zoho SalesIQ stay current in Gmail, so every call, text, or email goes to the right person at the right address.

How changes propagate between Gmail and Zoho SalesIQ

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.
  • Zoho SalesIQ: Subject to Zoho's per-plan API rate limits.
