HubSpot integrates with hundreds of business tools, but the most effective integrations depend on specific needs—whether automating workflows, syncing data, or enhancing sales and marketing. The best-performing integrations combine broad compatibility with specialized functionality. Zapier leads with 173,000 installs, connecting HubSpot to over 7,000 apps, while Make (formerly Integromat) and Workato offer advanced automation for complex workflows. For sales teams, DealHub, DocuSign, and LinkedIn Sales Navigator streamline quoting, contracts, and lead targeting, while Stripe and Shopify bridge e-commerce gaps. Marketing teams benefit from Mailchimp for email campaigns, Wistia for video analytics, and Google Search Console for SEO insights. Custom integrations via HubSpot’s API or platforms like Tray.io address niche requirements, though they may require developer support.

Key findings from the sources:

• Zapier is the most widely adopted connector (173K installs), automating workflows across 7,000+ apps ^[1].
• Sales-focused integrations like DealHub, DocuSign, and Gong dominate productivity rankings, reducing manual tasks by 30-50% ^[6].
• Marketing tools such as Mailchimp, Wistia, and Seventh Sense improve lead generation and engagement through automation and analytics ^[3][10].
• Custom integrations via API or platforms like Tray.io are essential for unique workflows but often require technical expertise ^[7].

Best HubSpot Integrations for Business Tools

Automation and Workflow Connectors

Automation platforms bridge HubSpot with thousands of apps, eliminating manual data entry and synchronizing processes across tools. These integrations are critical for scaling operations without increasing administrative overhead. The most effective solutions balance ease of use with advanced functionality, catering to both non-technical users and developers.

Zapier stands out as the most popular choice, with 173,000 installs and support for 7,000+ apps, including Gmail, Slack, and Trello ^[1]. Its no-code interface allows users to create "Zaps" (automated workflows) without programming knowledge. For example:

• Automatically add new HubSpot contacts to a Google Sheets spreadsheet for real-time reporting.
• Trigger Slack notifications when a high-priority deal is created in HubSpot.
• Sync HubSpot form submissions to Mailchimp for targeted email campaigns ^[9].

Make (formerly Integromat) offers deeper customization with 43,000 installs, supporting multi-step workflows and API-based integrations ^[1]. Unlike Zapier, Make allows for complex logic branches and data transformations, making it ideal for:

• Syncing HubSpot deals with custom objects in Salesforce, ensuring bidirectional data consistency.
• Aggregating data from multiple sources (e.g., Shopify orders, Stripe payments) into HubSpot for unified reporting ^[4].
• Automating lead scoring by pulling behavioral data from tools like Google Analytics into HubSpot.

For enterprises requiring enterprise-grade automation, Workato and Tray.io provide robust solutions with 4,000 and 2,000 installs respectively ^[1]. These platforms excel in:

• Handling large data volumes with minimal latency, critical for real-time sales and support operations.
• Supporting custom scripting for edge cases, such as validating lead data before syncing to HubSpot ^[7].
• Integrating legacy systems (e.g., ERP or on-premise databases) with HubSpot via secure APIs ^[9].

Challenges arise when syncing custom objects or non-standard data structures. Users report difficulties with pre-built connectors for account-based vs. company-based models, often requiring API-based custom solutions ^[7]. Developers recommend:

• Using HubSpot’s public API for tailored integrations when marketplace apps fall short.
• Leveraging webhooks for event-driven updates, such as triggering a HubSpot workflow when a payment is processed in Stripe ^[4].
• Testing integrations in a sandbox environment to avoid disrupting live data ^[9].

Sales and Marketing Productivity Tools

HubSpot’s integrations with sales and marketing tools directly impact revenue generation by streamlining lead management, contract processing, and customer engagement. The most transformative integrations reduce friction in the buyer’s journey while providing actionable insights for teams.

For sales teams, DealHub and DocuSign rank among the top productivity boosters, with DealHub offering a unified quoting platform that reduces proposal creation time by 40% ^[6]. Key features include:

• Dynamic pricing tables that auto-populate based on HubSpot deal stages.
• E-signature integration with DocuSign, eliminating the need to switch between tools.
• Real-time analytics on quote engagement, such as time spent viewing proposals ^[6].

• Prioritize leads based on LinkedIn activity (e.g., job changes, content engagement).
• Log InMail conversations directly to HubSpot contact records for context during follow-ups ^[6].
• Segment leads by industry or seniority for personalized outreach ^[5].

Marketing integrations focus on lead generation and nurturing. Mailchimp remains a staple for email marketing, with its HubSpot integration supporting:

• Two-way sync of contact lists and campaign performance metrics.
• Automated segmentation based on HubSpot lifecycle stages (e.g., MQL to SQL transitions) ^[3].
• A/B testing of email subject lines with results fed back into HubSpot for lead scoring ^[10].

For video marketing, Wistia integrates seamlessly with HubSpot to track viewer behavior, such as:

• Identifying which contacts watched key sections of a product demo video.
• Triggering follow-up emails in HubSpot when a viewer reaches a specific playback threshold (e.g., 75% completion) ^[3].
• Embedding videos in HubSpot landing pages with analytics tied to individual contacts ^[10].

• Sync customer purchase history with HubSpot for personalized post-purchase campaigns.
• Track abandoned carts in HubSpot and trigger recovery emails with discount codes ^[5].
• Attribute revenue to specific marketing channels (e.g., Facebook Ads) using UTM parameters ^[1].

Stripe’s integration simplifies payment processing by:

• Creating HubSpot deals automatically when a payment is processed.
• Syncing subscription statuses to HubSpot for renewal reminders or upsell opportunities ^[6].
• Generating invoices in HubSpot with payment links for faster collections ^[10].
