How to Trigger HubSpot Sequences from Call Outcomes

Your reps are making calls, leaving voicemails and logging outcomes, but if the follow-up depends on them remembering to send an email later, things will slip. The gap between “called” and “followed up” is where opportunities quietly die.

This hack shows you how to use HubSpot workflows and call outcomes to automatically enrol contacts into sequences. In the example here, we will focus on voicemail left and send an instant follow-up email plus a task reminder for the next call.

Why is this hack helpful?

Automating follow-up from call outcomes gives you a few big wins:

• No missed follow-ups: every logged call outcome triggers something, instead of relying on memory.
• Faster responses: contacts get an immediate email after a voicemail, while your brand is still top of mind.
• Consistent process: your “voicemail playbook” lives in workflows and sequences, not just in a team doc.
• Better prioritisation: different outcomes (Connected, voicemail, No answer) can each trigger different actions.

In short, you are turning call logs from “nice history” into actual next steps.

Steps to Set It Up

Step 1: Create a contact-based workflow

1. In HubSpot, go to Automation → Workflows
2. Click Create workflow
3. Choose Start from scratch and click Next
4. Select Contact-based workflow
5. Name your workflow something clear like:
   • Call Outcome → Sequence Enrolment
6. Click Create workflow

This workflow will listen for call outcomes on contact records and react accordingly.

Step 2: Set the enrolment trigger using call outcome

1. In your new workflow, click Set enrolment triggers
2. Click Add filter
3. Choose Activity properties
4. Select Call outcome
5. Set the criteria to is known
   • This ensures any call with an outcome logged can trigger the workflow
6. Click Apply filter

Enable re-enrolment

Because a contact can have multiple calls over time, you want them to re-enter the workflow whenever a new call outcome is logged.

1. In the enrolment settings panel, enable re-enrolment.
2. Confirm that re-enrolment is allowed when Call outcome is updated/known again.

This means the workflow will run every time a new call outcome is added for that contact.

Step 3: Branch the workflow by call outcome

You want different follow-up for different call results.

1. Click the + icon under your trigger to add an action
2. Select Branch
3. Under Branch based on, choose Activity
4. Select Call outcome

Choose the option to create a branch for each possible call outcome such as:

• Connected
• Left voicemail
• No answer
• Wrong number (if you use it)
• Busy

This creates a clear path for each outcome so you can define what happens next.

Step 4: Add actions under each outcome (Voicemail example)

Under each branch, you can now add sequence enrolments, tasks, or other actions that make sense.

Example: “Left voicemail” branch → enrol in sequence

1. Under the Left voicemail branch, click the + icon
2. Select Enrol in sequence
3. Choose the sequence you have set up for voicemail follow-up, for example:
   • A short email letting them know their Contact owner tried to call
   • A line that you will try again next day
4. Confirm that the sender is the correct owner and that this fits your sequence permissions and settings

This gives you an instant, consistent email follow-up whenever a voicemail is logged.

Bonus: Add a follow-up call task

Still under the Left voicemail branch:

1. Click + to add another action
2. Select Create task
3. Configure it as something like:
   • Task title: Follow-up call after voicemail
   • Due date: In 1 business day (or 24 hours if that matches your process)
   • Assigned to: Contact owner

Now reps get both:

• Automatic email follow-up via sequence.
• A clear reminder to call again.

Step 5: Define actions for other call outcomes (optional but recommended)

You do not have to, but it is smart to set up logic for other branches too:

• Connected:
  • Maybe no automatic sequence, or a different follow-up sequence based on call notes
• No answer:
  • Add a lighter follow-up or a specific task pattern
• Wrong number:
  • Update properties, stop outreach and log that the contact data needs fixing

The key is: each outcome can have its own small automation that reflects your sales playbook.

What this workflow achieves

• Trigger: Any call with a Call outcome logged for a contact
• Re-enrolment: Contacts can enter the workflow every time a new call outcome is added
• Branching: Workflow splits by Call outcome (Connected, Left voicemail, No answer, etc.)
• Actions (example):
  • For Left voicemail:
    • Enrol in a voicemail follow-up sequence
    • Create a follow-up call task 24 hours later

Every call turns into a clear, timely next step without manual admin.

Wrapping Up

Using call outcomes to drive sequence enrolment turns your HubSpot call logs into a live follow-up engine, not just a history book. Reps log the call, and HubSpot takes care of the next step, whether that is an email, a task, or both.
