# SendinBlue + HubSpot integration > Sync contacts, track campaign engagement, and automate lead nurturing between SendinBlue and HubSpot — no code required. **Canonical page:** https://tray.ai/connectors/sendinblue-hubspot-integrations/ **SendinBlue connector:** https://tray.ai/connectors/sendinblue-integrations/ **SendinBlue documentation:** https://tray.ai/documentation/connectors/service/sendinblue **HubSpot connector:** https://tray.ai/connectors/hubspot-integrations/ **HubSpot documentation:** https://tray.ai/documentation/connectors/service/hubspot ## Overview SendinBlue and HubSpot do different jobs, and that's exactly why they work well together. SendinBlue handles transactional email, SMS campaigns, and marketing automation. HubSpot brings the CRM, deal pipeline, and sales enablement. Running them separately means duplicate data entry, inconsistent contact records, and no clear picture of what actually drove a conversion. Connect the two and you get a continuous view of every customer interaction, from first email open to closed deal. When SendinBlue and HubSpot run independently, marketing and sales spend their time exporting lists, reconciling contacts, and guessing at which campaigns moved the needle. Once they're connected, every contact added in HubSpot lands in the right SendinBlue list automatically, and every email engagement — opens, clicks, bounces, unsubscribes — flows back into HubSpot as activity data. Sales reps get real-time email intelligence before they pick up the phone. Marketers can segment campaigns by CRM deal stage. Compliance teams have one authoritative record for opt-in status. The practical result: less back-and-forth between teams, faster follow-up on warm leads, and actual attribution across the customer journey. ## Use cases ### Bidirectional Contact Sync Between HubSpot and SendinBlue Keep contact records aligned by automatically syncing new and updated contacts between HubSpot and SendinBlue in real time. When a sales rep creates a contact in HubSpot, it appears in the right SendinBlue list immediately, and vice versa. Field-level mapping keeps properties like lifecycle stage, phone number, and company name consistent across both platforms. - Eliminate manual CSV imports and exports between platforms - Reduce data discrepancies that cause miscommunication between sales and marketing - Enroll every new contact in the correct SendinBlue marketing list immediately ### Sync Email Engagement Data from SendinBlue into HubSpot Contact Records Automatically push SendinBlue email engagement events — opens, clicks, bounces, unsubscribes — into HubSpot as contact activity or custom properties. Sales reps can see whether a prospect engaged with a recent campaign before they call. That context makes outreach smarter and less awkward. - Give sales reps full visibility into a contact's email history inside HubSpot - Trigger HubSpot workflows based on SendinBlue email activity - Improve lead scoring accuracy by incorporating email engagement signals ### Enroll HubSpot Leads in SendinBlue Nurture Sequences by Lifecycle Stage When a contact in HubSpot moves to a new lifecycle stage — say, from Subscriber to Marketing Qualified Lead — automatically enroll them in the matching SendinBlue email sequence. Every lead gets relevant, timely content without anyone on the marketing team having to do it manually. As the contact progresses, their SendinBlue list membership updates to match. - Deliver the right content at every stage of the buyer journey automatically - Reduce the risk of leads going cold during handoff stages - Increase conversion rates with precisely timed nurture campaigns ### Manage SendinBlue Unsubscribes and Opt-Outs in HubSpot Automatically reflect SendinBlue unsubscribes, bounces, and GDPR opt-out events back to the corresponding HubSpot contact record. Your sales team won't accidentally email someone who already opted out on the marketing side. Audit trails in both systems stay current without manual oversight. - Maintain GDPR and CAN-SPAM compliance across both platforms simultaneously - Prevent accidental outreach to opted-out contacts by sales reps in HubSpot - Reduce spam complaints and protect your sender reputation ### Create HubSpot Deals or Tasks When SendinBlue Contacts Hit Engagement Thresholds Set up rules that watch SendinBlue campaign engagement and automatically create a HubSpot deal, task, or note when a contact crosses a defined threshold — clicking a pricing page link, opening three emails in a week, that kind of thing. Sales teams can act on genuine buying signals without waiting for a manual handoff. - Convert high-intent email behavior directly into sales pipeline activity - Reduce response time on hot leads by alerting sales reps instantly - Prioritize outreach based on real engagement data rather than guesswork ### Sync HubSpot Deal Stage Changes to Trigger SendinBlue Transactional Emails Use HubSpot deal stage updates to fire SendinBlue transactional or operational emails — proposal confirmations, onboarding welcome messages, renewal reminders. Customers get timely communication tied to where they actually are in the sales process, and sales reps don't have to send the same templated email at every deal milestone. - Automate customer communication at every stage of the deal pipeline - Ensure consistent messaging regardless of which sales rep owns the deal - Free up sales rep time by eliminating repetitive email-sending tasks ### Segment HubSpot Contacts for Targeted SendinBlue Campaigns Using CRM Data Use HubSpot CRM data — industry, company size, deal history, custom properties — to build targeted SendinBlue campaign lists without manual exports. When a contact's CRM properties change in HubSpot, their SendinBlue list membership updates automatically. Marketers get granular CRM segmentation without leaving their email platform. - Build precise email segments using CRM attributes that aren't available natively in SendinBlue - Eliminate scheduled CSV exports to refresh campaign audiences - Increase email relevance and open rates with more accurate audience segmentation ## Templates ### Sync New HubSpot Contacts to SendinBlue Lists Automatically Whenever a new contact is created in HubSpot, this template adds them to a mapped SendinBlue list based on their lifecycle stage or source, so every new lead enters the right marketing sequence without delay. Connectors used: HubSpot, SendinBlue ### Push SendinBlue Email Events to HubSpot Contact Timeline This template listens for email engagement events in SendinBlue — opens, clicks, bounces, unsubscribes — and logs them as timeline activities or updates custom properties on the matching HubSpot contact record. Connectors used: SendinBlue, HubSpot ### Create HubSpot Task for Sales Rep When SendinBlue Contact Clicks a High-Intent Link Automatically create a follow-up task assigned to the contact owner in HubSpot whenever a SendinBlue contact clicks a high-intent link — a pricing page, demo request, or case study download. Connectors used: SendinBlue, HubSpot ### Sync HubSpot Lifecycle Stage Changes to SendinBlue List Membership When a HubSpot contact's lifecycle stage changes, this template updates their SendinBlue list membership, enrolling them in the right nurture sequence and removing them from prior stage lists to prevent duplicate messaging. Connectors used: HubSpot, SendinBlue ### Propagate SendinBlue Unsubscribes to HubSpot for Compliance This template ensures that any contact who unsubscribes or receives a hard bounce in SendinBlue has their communication preferences updated in HubSpot immediately, so your team doesn't inadvertently contact them again. Connectors used: SendinBlue, HubSpot ### Trigger SendinBlue Transactional Email on HubSpot Deal Stage Change Automatically send a targeted SendinBlue transactional email to a contact whenever their associated HubSpot deal moves to a specified stage, such as Proposal Sent, Contract Signed, or Onboarding Started. Connectors used: HubSpot, SendinBlue ## Challenges Tray.ai solves ### Keeping Contact Records in Sync Across Two Separate Platforms HubSpot and SendinBlue each maintain their own contact databases with different field structures, so updates in one system don't automatically appear in the other. Without integration, teams deal with duplicate records, stale data, and inconsistent segmentation that hurt both sales and marketing. **How Tray.ai helps:** Tray.ai provides a flexible field mapping layer that aligns HubSpot and SendinBlue contact schemas, supporting bidirectional sync with custom transformation logic to handle mismatched field names, data types, and list structures without manual reconciliation. ### Translating SendinBlue Webhook Events into Actionable HubSpot Data SendinBlue fires webhook events for email opens, clicks, and bounces, but HubSpot can't consume those raw payloads natively. They need parsing, contact matching, and transformation before they can enrich a contact record or kick off a workflow. **How Tray.ai helps:** Tray.ai's workflow engine receives and parses SendinBlue webhooks in real time, looks up the contact in HubSpot by email, and writes the engagement data to the correct fields or timeline entries — no custom code or middleware required. ### Avoiding Duplicate Contacts Created by Concurrent Syncs When both HubSpot and SendinBlue are active and contacts are created in both systems at the same time, careless sync workflows produce duplicate records that fragment customer history and break list segmentation. **How Tray.ai helps:** Tray.ai workflows use an upsert pattern that checks for an existing record before creating a new one, using email address as a deduplication key so contacts are updated rather than duplicated regardless of which system triggers the sync. ### Managing GDPR and Email Compliance Across Both Systems Opt-out and unsubscribe events in SendinBlue need to reach HubSpot immediately — otherwise sales reps can inadvertently contact people who already opted out. There's no native way to pass these compliance events between the two platforms. **How Tray.ai helps:** Tray.ai listens for SendinBlue unsubscribe and bounce webhooks and instantly updates the corresponding HubSpot contact's communication preferences, keeping both systems in agreement and reducing the risk of contacting someone who's already said no. ### Handling API Rate Limits During Large Batch Syncs Bulk contact syncs between HubSpot and SendinBlue — migrating a large list or backfilling historical records — can exhaust API rate limits on either platform quickly, causing sync failures or partial data loads that are hard to detect and recover from. **How Tray.ai helps:** Tray.ai includes built-in rate limit handling and retry logic that automatically throttles requests, queues payloads, and retries failed calls with exponential backoff, so large-volume syncs finish reliably without anyone watching over them. ## 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/
