HubSpot has powerful built-in automation — workflows, sequences, and smart content that make it one of the most capable CRMs on the market. But HubSpot's automation stops at HubSpot's walls. When you need to connect HubSpot to tools it doesn't natively integrate with — or when you need cross-tool workflows that span HubSpot, Slack, Google Sheets, Shopify, and more — that's where external HubSpot automation comes in.
Before building external automation, use what's already there:
If your automation needs are entirely within HubSpot's ecosystem, these tools may be sufficient. The need for external automation arises when you want HubSpot talking to tools outside its universe.
When a new contact is created in HubSpot or a contact property changes, sync that data to a Google Sheet. This gives non-HubSpot users (like finance or operations) visibility into the sales pipeline without needing CRM access.
HubSpot can send email notifications, but Slack is faster. When a deal moves to a critical stage — "Proposal Sent", "Verbal Commit", "Closed Won" — send a Slack notification to the rep and their manager with the deal details and next steps.
When a prospect fills out a Typeform (demo request, pricing inquiry, contact form), automatically create a HubSpot contact with all their details, assign them to the right owner, and tag them with their lead source.
When a new customer places a Shopify order, create or update their HubSpot contact with purchase data. This connects your e-commerce data with your marketing CRM — enabling post-purchase campaigns, upsell workflows, and retention marketing based on purchase history.
When a high-value lead takes a key action (like filling out a pricing form), send an SMS to the assigned rep's phone. Faster than email, harder to miss.
Set up a Slack command or a #create-task channel. When someone posts a message there, automatically create a HubSpot task assigned to the relevant rep with the message content and due date.
The most effective HubSpot automation doesn't think in terms of individual triggers and actions — it thinks in terms of complete customer journeys:
