How to Add Birthday Field to HubSpot

You want to send a birthday message to a contact. But when you open HubSpot, there’s no birthday field sitting there waiting for you.

That’s not a bug. It’s a design choice — and you can fix it in about five minutes.

HubSpot doesn’t include a native birthday property by default, but it gives you everything you need to create one. Once it’s set up, you can use it to trigger automated workflows, personalize outreach, and build the kind of relationship-first touchpoints that actually move people.

This guide walks you through the exact steps — plus how to put that birthday data to work once you have it.

Why Birthday Fields Matter More Than You Think

Personalization isn’t a nice-to-have anymore. It’s table stakes.

• 80% of consumers are more likely to do business with a company that offers personalized experiences (Epsilon).
• Birthday emails generate 342% higher revenue per email than standard promotional emails (Experian).
• Triggered emails like birthday messages have 152% higher click-through rates than batch emails (Epsilon).
• 72% of buyers only engage with messages tailored to their interests (SmarterHQ).
• Companies that excel at personalization generate 40% more revenue than average players (McKinsey).

A birthday field in HubSpot is a small data point. But it opens the door to automations that feel personal, timely, and human — which is exactly what drives replies and relationships.

What You’ll Need Before You Start

No special permissions required beyond basic HubSpot access. You just need:

• A HubSpot account (any tier — free through Enterprise)
• Access to Contact Properties (Settings → Properties)
• Optionally: a workflow setup if you want automation

That’s it. Let’s build it.

How to Add a Birthday Field in HubSpot

Step 1 — Open Your Contact Properties

Go to your HubSpot portal and click the Settings icon (gear icon) in the top right navigation bar.

From the left sidebar, navigate to:

Data Management → Properties

Make sure you’re in the Contact tab. This is where all contact-level properties live — including the one you’re about to create.

Step 2 — Create a New Property

Click the orange “Create property” button in the top right corner.

A panel will slide open on the right side of your screen. Here’s what to fill in:

• Object type: Contact
• Group: Choose a relevant group like “Contact Information” or create a custom group like “Personal Details”
• Label: Birthday
• Internal name: This auto-populates as birthday — leave it as is unless you have a naming convention

Click Next to move to the field type selection.

Step 3 — Choose the Right Field Type

This is where most people get tripped up. You have a few options, and each one has trade-offs.

Option A: Date Picker

This is the cleanest option if you want to capture a full date (month, day, year). HubSpot stores it as a date value, making it easy to use in workflows and filters.

• Select Field type → Date picker
• Click Create to save

Option B: Number Fields (Month + Day)

If you only want month and day (useful for annual recurring workflows regardless of year), create two separate number properties:

• Birthday Month (number, 1–12)
• Birthday Day (number, 1–31)

This approach gives you more flexibility for automations that fire every year on the same date.

Recommended: Use the Date picker for simplicity unless you specifically need year-independent logic.

Step 4 — Add the Field to Your Forms and Records

Creating the property doesn’t automatically surface it everywhere. You need to add it manually where it’s relevant.

To add to a Contact record view:

1. Open any Contact record
2. Click “More” or the pencil icon in the properties panel
3. Search for “Birthday” and add it to your sidebar view

To add to a Form:

1. Go to Marketing → Forms and open the form you want to edit
2. In the form editor, search for “Birthday” in the property list on the left
3. Drag it into your form fields

To bulk-update existing contacts:

Use an import. Create a CSV with two columns — Email (to match records) and Birthday — then go to Contacts → Import and map the columns.

Step 5 — Set Up a Birthday Workflow (Optional but Powerful)

Once the field exists, you can trigger automations off it.

Go to Automation → Workflows and click Create workflow → Start from scratch.

Choose Contact-based and set the enrollment trigger as:

• Property: Birthday
• Date: Is equal to → select “today” (or X days before today for pre-birthday messages)

From there, build your sequence:

• Send a personalized birthday email
• Create a task for a rep to reach out
• Add a tag or update a lifecycle stage

HubSpot’s date-based triggers let you send these automations annually by checking the “Re-enroll” box — meaning contacts get a touchpoint every year without any manual work.

How to Actually Use Birthday Data for Outreach

Here’s the honest truth: collecting a birthday and sending a generic “Happy Birthday! 🎂” email with a discount code isn’t what moves the needle.

What works is using the birthday as a natural, human reason to reach out.

A sales rep touching base on a contact’s birthday gets a response rate most cold outreach will never see. It signals that you actually know who they are — not just their job title.

A few high-impact use cases:

• Re-engagement play: Birthday touchpoint to contacts who’ve gone quiet in the last 90 days
• Decision-maker relationship building: A short, personal note with no ask — just acknowledgment
• Gifting workflow: Trigger a gift send (via Sendoso, Alyce, or similar) for high-value accounts
• Trial or renewal timing: Use birthday as a soft warm-up before a renewal conversation

The birthday field is one data point. But data points, used smartly, create the kind of human moments that build pipelines.

Common Mistakes to Avoid

Using text field instead of date picker

A plain text field means no workflow logic, no date filtering, and no automation triggers. Always use date picker or number fields.

Not setting a default display format

HubSpot date pickers default to MM/DD/YYYY in US accounts. If your team is international, double-check the format in your portal settings to avoid confusion.

Skipping the re-enrollment trigger

If you forget to enable re-enrollment in your workflow, it fires once and never again. Birthday workflows need to recur annually — make sure that box is checked.

Collecting birthday but never using it

This one is the most common. The field exists, data gets filled in, and nothing happens. Set the workflow up the same day you create the property.

How to Add Birthday Field to HubSpot in Different Plan Tiers

The property creation process is identical across all HubSpot plans. What differs is workflow capability:

If you’re on Free or Starter, you can still collect birthday data and have reps manually act on it. The automation layer kicks in at Professional.

Conclusion

Adding a birthday field to HubSpot takes less than five minutes. The setup is straightforward — create a custom contact property, choose the date picker type, add it to your relevant forms and views, and build a workflow if you’re on Professional or Enterprise.

But the real opportunity isn’t in the setup. It’s in what you do with the data.

Birthday touchpoints are one of the few outreach moments where the context is built-in and the reason to reach out needs no explanation. Done right, they drive genuine responses, re-engage cold contacts, and build the kind of relationships that generate pipeline over time.

Set up the field. Build the automation. And start treating your CRM data like the strategic asset it actually is.
