Take control of your workflow velocity. Throttle lets you rate limit, queue, and drip records through HubSpot workflows at exactly the pace you need — no more API overloads, no more flooded inboxes.
Capabilities
Set precise delays between record processing. Seconds, minutes, or hours — choose the interval that keeps your downstream systems happy.
Assign priority levels to queued records. High-value deals jump the line while routine updates wait their turn.
Process records in controlled batches. Send 50 at a time, 100 at a time, or whatever your API rate limits allow.
Each workflow gets its own throttle settings. A slow drip for email campaigns, fast throughput for data sync — independently configured.
Restrict processing to business hours only. No more emails sent at 3 AM or API calls hitting during maintenance windows.
See your queue depth, processing rate, and estimated completion time. Know exactly when the last record will be processed.
Use Cases
Whether you're avoiding API limits or pacing outreach for maximum impact.
Spread email sends across hours or days instead of blasting your entire list at once. Improve deliverability and avoid spam filters.
Calling third-party APIs from workflows? Throttle ensures you stay within rate limits and never lose data to 429 errors.
Migrating data, updating thousands of records, or triggering bulk actions? Pace the work so your portal stays responsive.
Limit how many prospects enter a sequence per day. Ensure your reps aren't overwhelmed and every lead gets proper attention.
Technical Details
Built on Google Cloud Run with Cloud Tasks for durable, exactly-once queue processing.
Durable queue — Records are persisted in Cloud Tasks. Nothing is lost if a service restarts or scales down.
Workflow action — Drop Throttle into any HubSpot workflow as a custom action. Configure delay, batch size, and schedule right in the workflow editor.
Callback integration — Uses HubSpot's automation v4 callback API. Records are held until released, then the workflow continues seamlessly.
Business hours engine — Configurable timezone and working hours. Records queued outside hours are held until the next window opens.
