HubSpot + ColdSend
Sync ColdSend replies, bounces, and engagement events into HubSpot contacts, deals, and activities using ColdSend webhooks and a simple bridge.
How it works
Create a ColdSend webhook
In ColdSend, go to Settings → Webhooks and create an endpoint that will receive reply, bounce, open, click, and unsubscribe events.
Choose your bridge
Point the webhook at Zapier, Make, n8n, or your own endpoint. This bridge transforms ColdSend payloads into HubSpot CRM API calls.
Connect HubSpot
Authenticate to HubSpot with a private app token (or Zapier/Make/n8n's HubSpot connection) and map ColdSend fields to HubSpot properties.
Map events to HubSpot objects
For example: reply_received → create/update contact + deal + task; email_bounced → set email invalid; lead_unsubscribed → update opt-out property.
Need detailed setup steps?
Start with the Using Webhooks to Receive Real-Time Events guide to create and secure your ColdSend webhook endpoint. Then route events to your bridge and call HubSpot's Contacts, Deals, and Engagements APIs.
For a no-code approach, use Zapier's Webhooks by Zapier trigger → HubSpot actions, or equivalent Make/n8n modules.
Why sync HubSpot with ColdSend?
HubSpot is a common source of truth for outbound teams, but ColdSend does not have a native two-way HubSpot integration. Instead, ColdSend's webhook events give you the raw data you need to keep HubSpot contacts, deals, and activities in sync through a simple bridge.
This approach is flexible: you decide which events matter, how fields map, and whether to use a no-code tool or a custom endpoint.
Who is this for?
Sales teams, agencies, and RevOps teams that want ColdSend campaign activity reflected in HubSpot without waiting for a native connector.
What you get
When a lead replies, create or update a HubSpot contact and log the reply as an engagement.
Create or update a HubSpot deal when a prospect shows interest or books a meeting.
Log sent emails, opens, clicks, bounces, and unsubscribes against contact records.
Own the mapping logic. Use Zapier, Make, n8n, or a small custom endpoint to transform and forward events.
