Why teams connect Google Sheets and Lemlist
Stop re-entering the same information in Google Sheets and Lemlist: Stacksync keeps the records they share consistent in real time, in both directions.
Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.
Stacksync syncs Named ranges, Cell values, Spreadsheets, Sheets (tabs) in Google Sheets with Webhooks, Team Members, Campaigns, Leads in Lemlist in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.
Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.
Common use cases
- Prototype an integration by syncing a sheet before committing to a database schema.
- Give ops and finance teams an editable spreadsheet view of CRM or database records, with edits written back to the source.
- Mirror campaign performance data into BI tools for outbound reporting across senders
- Sync replies, opens, and bounces from Lemlist into the CRM so outbound activity shows on lead and contact records
Where both tools track people or companies: one consistent record
Contact and company details corrected in either tool update the other, so nobody works from the old version.
Where one tool produces events: mirror them in the other
Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.
Where Lemlist is where the team documents or plans: keep its data fed
Information that originates in Google Sheets stays current in Lemlist instead of going stale after a one-time paste.
What you can sync between Google Sheets and Lemlist
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.
| Google Sheets objects | Lemlist objects | |
|---|---|---|
| Named ranges Stable references that keep sync mappings valid when the grid moves. | Team Members Sender and seat records map outreach activity to reps in other systems. | |
| Cell values Untyped by default, so syncs handle type coercion for dates and numbers. | Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | |
| Spreadsheets The file-level container a sync connects to, identified by spreadsheet ID. | Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | |
| Sheets (tabs) Individual worksheets, typically mapped one-to-one to a synced table. | Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | |
| Rows Treated as records; a header row usually defines field names. | Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | |
| Ranges Addressed in A1 notation for batched reads and writes. | Webhooks Hook subscriptions define which activity events are pushed to external endpoints. |
