# Connect Lemlist to HubSpot > Sync cold email campaigns with your CRM automatically so your sales team always has the full picture. **Canonical page:** https://tray.ai/connectors/lemlist-hubspot-integrations/ **Lemlist connector:** https://tray.ai/connectors/lemlist-integrations/ **Lemlist documentation:** https://tray.ai/documentation/connectors/service/lemlist **HubSpot connector:** https://tray.ai/connectors/hubspot-integrations/ **HubSpot documentation:** https://tray.ai/documentation/connectors/service/hubspot ## Overview Lemlist and HubSpot do very different things. Lemlist runs personalized outreach at scale; HubSpot tracks relationships, pipelines, and deals. Without an integration, reps end up manually logging email activity, updating contact records, and reconciling engagement data across both platforms. Connecting Lemlist with HubSpot through tray.ai cuts out that friction — every campaign interaction flows directly into your CRM in real time. When Lemlist and HubSpot run in silos, engagement signals get lost. A prospect who clicked a Lemlist email three times or replied positively should immediately trigger pipeline movement in HubSpot — but without automation, that handoff depends entirely on manual effort. Integrating the two platforms lets revenue teams automatically create and update HubSpot contacts from Lemlist campaign data, push reply statuses and engagement scores into deal records, enroll leads into the right HubSpot sequences the moment they respond, and give sales managers a unified view of outreach performance alongside pipeline health. The result is faster follow-up, less administrative overhead, and a sales process that scales without adding headcount. ## Use cases ### Auto-Create HubSpot Contacts from Lemlist Campaign Leads When a new lead is added to a Lemlist campaign, tray.ai automatically creates or updates the corresponding contact record in HubSpot, so your CRM stays current without manual data entry. Fields like company, job title, and campaign source are mapped and synced immediately. Sales reps have clean, enriched contact data waiting before they make the first call. - Eliminate manual contact creation and reduce data entry errors - Make sure every outreach lead is tracked within your CRM pipeline - Populate HubSpot contacts with Lemlist campaign source and enrollment date automatically ### Log Lemlist Email Opens and Clicks as HubSpot Activities Every time a prospect opens or clicks a Lemlist email, tray.ai logs that engagement as a CRM activity on the corresponding HubSpot contact. Sales reps get full visibility into prospect interest directly within their HubSpot timeline — no more toggling between platforms to understand where a lead stands. - Build a complete engagement timeline inside HubSpot for every contact - Help reps prioritize follow-up based on real email engagement signals - Reduce tool-switching and keep salespeople focused in one platform ### Move HubSpot Deals to a New Stage When Prospects Reply to Lemlist When a contact replies to a Lemlist email sequence, tray.ai automatically advances the associated HubSpot deal to the next pipeline stage and notifies the deal owner. This removes the lag between a prospect showing interest and a rep taking action. High-intent signals don't get buried, and pipeline data reflects reality in real time. - Accelerate pipeline progression by automating deal stage updates on reply - Instantly notify the right sales rep when a prospect engages - Keep HubSpot pipeline data accurate without relying on manual updates ### Enroll HubSpot Contacts into Lemlist Campaigns Based on Lifecycle Stage When a HubSpot contact reaches a specific lifecycle stage or is assigned a particular deal stage, tray.ai automatically enrolls them into the right Lemlist outreach campaign. Leads get timely, relevant messaging the moment they hit a qualifying milestone. Marketing and sales teams can configure enrollment rules without writing any code. - Trigger outreach campaigns automatically based on CRM lifecycle changes - Reach prospects with relevant messaging at the right moment - Remove the manual step of exporting lists and importing them into Lemlist ### Unsubscribe Contacts Across Both Platforms in Real Time When a prospect unsubscribes or marks a message as spam in Lemlist, tray.ai immediately updates the contact's communication preferences in HubSpot and removes them from active outreach sequences. This two-way sync also works in reverse — contacts who opt out in HubSpot are automatically removed from Lemlist campaigns. Stay compliant with GDPR and CAN-SPAM without any manual list management. - Stay compliant with email regulations across both platforms simultaneously - Protect sender reputation by removing unsubscribes from active campaigns instantly - Avoid outreach to contacts who have already opted out ### Sync Lemlist Campaign Performance Metrics into HubSpot Reports Aggregate Lemlist open rates, reply rates, bounce rates, and click-through data into custom HubSpot contact or company properties on a scheduled basis. Revenue operations teams can build unified dashboards that show how outreach performance ties to pipeline creation and deal velocity. Leadership gets the full story without logging into multiple platforms. - Centralize outreach analytics inside HubSpot for unified reporting - Correlate email campaign engagement with pipeline and revenue outcomes - Save RevOps teams hours of manual data consolidation each week ### Trigger HubSpot Tasks for Sales Reps When Lemlist Sequences End When a prospect completes a Lemlist email sequence without replying, tray.ai automatically creates a follow-up task in HubSpot and assigns it to the contact owner. No lead falls through the cracks at the end of an automated sequence. Reps are prompted to take a personalized next step — a phone call, LinkedIn message, or custom email — at exactly the right moment. - Prevent leads from going cold after sequences end without a response - Automate task creation so sales reps always know their next action - Bridge automated outreach and personalized human follow-up ## Templates ### New Lemlist Campaign Lead → Create or Update HubSpot Contact Automatically creates a new HubSpot contact or updates an existing one whenever a lead is added to a Lemlist campaign, syncing name, email, company, and campaign source fields without manual effort.

Without solid deduplication logic, automations can create duplicate contacts or update the wrong record entirely. **How Tray.ai helps:** tray.ai's workflow logic lets teams build custom deduplication steps that search HubSpot by email before creating any new record, and apply normalization rules to handle case sensitivity and formatting discrepancies. Conditional branching means the workflow creates, updates, or skips records based on precisely defined match criteria. ### Handling Lemlist Webhook Volume at Scale High-volume Lemlist campaigns can generate thousands of webhook events — opens, clicks, replies, bounces — in a short window. Basic integrations often hit HubSpot API rate limits or drop events, leaving gaps in CRM data. **How Tray.ai helps:** tray.ai handles webhook ingestion with built-in queuing and retry logic, so no events are lost during traffic spikes. Rate limit handling is built into the HubSpot connector, automatically throttling requests to stay within API limits and retrying failed calls without manual intervention. ### Keeping Opt-Out and Compliance Data Synchronized Bidirectionally Managing unsubscribes across Lemlist and HubSpot in both directions is a real compliance risk. A contact who opts out in one platform may keep receiving outreach from the other, exposing the company to GDPR and CAN-SPAM violations. **How Tray.ai helps:** tray.ai supports true bidirectional sync workflows that listen for opt-out events in both Lemlist and HubSpot at the same time. When an unsubscribe is detected in either system, the workflow immediately updates the other platform's communication preferences, so no opted-out contact receives unwanted outreach from either direction. ### Mapping Custom Fields Between Platforms Without a Developer Sales teams often use custom properties in HubSpot and custom attributes in Lemlist that don't map to each other out of the box. Keeping those field mappings current as both platforms change is tedious and error-prone, especially for non-technical users. **How Tray.ai helps:** tray.ai's visual workflow builder includes a drag-and-drop data mapper that lets RevOps and sales operations teams configure and update field mappings without writing code. When custom properties change in either platform, the mapping can be updated in minutes, and changes propagate across all affected workflows immediately. ### Triggering the Right Campaign Based on Complex HubSpot Segmentation Enrolling contacts in the correct Lemlist campaign based on nuanced HubSpot criteria — a combination of industry, deal stage, and lead score, for example — is hard to implement without flexible conditional logic. Simple if-then tools often can't handle the complexity needed for precise audience targeting. **How Tray.ai helps:** tray.ai supports multi-condition branching and advanced filtering within workflows, letting teams evaluate multiple HubSpot properties simultaneously before routing a contact to the right Lemlist campaign. Boolean logic, list membership checks, and numeric comparisons can all be combined into a single workflow without any custom code. ## Learn more - Intelligent Integration: https://tray.ai/platform/intelligent-ipaas/ - Merlin Agent Builder: https://tray.ai/platform/merlin-agent-builder/ - Agent Gateway for MCP: https://tray.ai/platform/agent-gateway/ - Book a demo: https://tray.ai/contact/
