Smartlead + HubSpot integration
Smartlead's native HubSpot sync logs engagement as notes. OutboundSync writes every send, open, click, reply, and category change as a structured HubSpot timeline event.

Smartlead + HubSpot at a glance
Yes, Smartlead integrates with HubSpot through OutboundSync. Each Smartlead event (sends, opens, link clicks, replies, bounces, unsubscribes, and lead category updates) becomes a structured timeline event on the matching HubSpot Contact. HubSpot lists can also be synced to Smartlead as block lists, so suppression is managed where your customer data already lives.
| Status | Live |
|---|---|
| Channels | |
| Direction | Activity Smartlead → HubSpot; block lists HubSpot → Smartlead |
| HubSpot records | Contacts, with optional Company association |
| Block lists | Yes, from HubSpot lists |
| Smartlead plan | Pro or higher |
| Setup | Self-serve: install the app from the HubSpot App Marketplace |
Smartlead's built-in HubSpot connector is fine for basic logging: sends and replies arrive as email activities. Opens, clicks, bounces, and unsubscribes land as notes, though, and notes are hard to filter, trigger on, or report against. OutboundSync treats every one of those events as a first-class timeline event with campaign and sequence details attached.
Lead categories are where this pays off. When a reply is categorized in Smartlead, the change shows up on the Contact as its own event and in OutboundSync Contact properties. HubSpot workflows can branch on it the same minute, whether that means routing an interested reply to an AE or pausing marketing email for someone who said not now.

Every event below arrives in near-real time and lands on the matched HubSpot record. Pick the ones you want per source.
| Event | Channel | Where it lands in HubSpot |
|---|---|---|
| Email sent— Includes manual replies sent from the Smartlead inbox | Email timeline event on the Contact | |
| Email opened | Email timeline event on the Contact | |
| Link clicked | Email timeline event on the Contact | |
| Reply received | Email timeline event on the Contact, with the reply text | |
| Email bounced | Email timeline event on the Contact | |
| Lead unsubscribed | Email timeline event on the Contact | |
| Lead category updated— Smartlead's built-in and custom lead categories | Timeline event plus OutboundSync Contact properties |
Event names come from the Smartlead webhooks OutboundSync receives. See the Smartlead event reference.

Ways to connect Smartlead and HubSpot
The options teams weigh before they commit a production sync.
| Option | What it does | Trade-off |
|---|---|---|
| Smartlead's native HubSpot connectorNative integration comparison | Logs sends and replies as HubSpot email activities, maps custom fields, and can auto-create deals from lead categories. | Opens, clicks, bounces, and unsubscribes are logged as notes rather than structured activity, it runs primarily one-way, and it does not move deal stages.Source: helpcenter.smartlead.ai, smartlead.ai |
| Zapier, Make, or n8nCompare integration platforms | Catch Smartlead webhooks and write each event to HubSpot with a workflow you build. | Every event type, retry, and field change is a workflow you maintain, billed per task or step. |
| Custom buildBuild vs buy | Write your own service against the Smartlead and HubSpot APIs. | You own matching, deduplication, API limits, and every upstream schema change. |
| OutboundSync | Pre-built email activity sync into HubSpot Contacts, with HubSpot lists pushed back as block lists. | Self-serve setup, searchable event logs, and support from the team that maintains the connector. |

HygraphSmartlead + HubSpot FAQ
What Smartlead activity does OutboundSync sync to HubSpot?

Smartlead events land as email timeline event on the Contact; or email timeline event on the Contact, with the reply text; or timeline event plus OutboundSync Contact properties. See the HubSpot data model docs for details.What's the difference between Smartlead's native HubSpot sync and OutboundSync?
The native sync logs sends and replies as email activities but records opens, clicks, bounces, and unsubscribes as notes, and it runs mostly one way. OutboundSync writes every event as a structured timeline event and pushes HubSpot lists back to Smartlead as block lists.Is the integration one-way or two-way?
Activity flows one way, from Smartlead into HubSpot. The only write-back is block lists: HubSpot lists you choose are pushed to Smartlead so those records are suppressed.Do I need admin access to set it up?
A HubSpot Super Admin installs the OutboundSync app and keeps it authorized.Which Smartlead plan do I need?
OutboundSync requires Smartlead's Pro plan or higher, because it relies on Smartlead's webhook and API features.How is Smartlead + HubSpot priced?
OutboundSync bills on sent messages per month. Replies, opens, clicks, and lead-category updates are not billed. Plan details are on the pricing page.Can I do this with Zapier, Make, or n8n?
For lightweight Smartlead automations, yes. When you need dependable attribution and suppression, generic builders get expensive and brittle at volume. OutboundSync is pre-built, keeps searchable event logs beyond 30 days, and prices by outbound volume instead of step count.What breaks first when this scales?
Data quality and reliability break first: duplicate events, retries, out-of-order webhooks, and bursts during big sends. OutboundSync handles idempotency, timing buffers, and queue recovery, and flags suspicious or mismapped payloads instead of writing them.
