Why we built a new HubSpot Integration
One of our clients has a rugby academy (yes, we are based in New Zealand), and they ask, “how do we filter age groups for our junior players?”. “Ummm. I don’t know, I’ll know,” I replied. However, a quick search on HubSpot revealed that there are features to automate based on annual events, even birthdays. How does HubSpot know how to get started on your next birthday? And how do we calculate the age of contact? In short, no. So.
When Kiwi says there is nothing we can do in HubSpot, we build partnerships to make the impossible possible.
Common Problems with Default HubSpot Birthday Field
The default birthday property in HubSpot:
| Issue | Explanation | Impact |
| Text-Based Field | Not always structured as date format | Cannot calculate age automatically |
| No Auto Age Update | Age does not refresh yearly | Manual updates required |
| No Next Birthday Logic | Cannot trigger annual automation | Workflow limitations |
| Limited Filtering | Difficult to create smart age lists | Segmentation gaps |
This is why many businesses search for How to Add Birthday Field to HubSpot CRM properly.
Introducing our new Birthday HubSpot Addition – How to Add Birthday Field to Hubspot
Here’s how our original HubSpot Integration works.
We’ve created a group of 3 custom possessions for Contacts:
- Date of Birth – Genuine (we’ll get to that in a minute)
- Date of Birth – Age
- Date of Birth – Next Birthday.
And we’ve created a HubSpot workflow to create updates to your contact’s features. For example, the integration sets the age and other birthdays each time you add or update a contact’s birthday.
Step-by-Step: How to Add Birthday Field to HubSpot
How to Add Birthday Field to HubSpot (Proper Setup)
| Step | Action | Tool Location |
| 1 | Go to Settings → Properties | HubSpot CRM |
| 2 | Create New Property | Contact Object |
| 3 | Select Field Type = Date Picker | Ensures automation compatibility |
| 4 | Name Property “Date of Birth (Date)” | Avoid text-based field |
| 5 | Add to Forms | Marketing → Forms |
| 6 | Test Submission | Confirm date format |

So why did we add new stuff for date of birth when there’s already one in HubSpot?
The avoidance date of birth in the HubSpot property is an actual text field, not a date field filled with ad integration. Therefore, modifying or calculating data from a text box is unreliable.
The new date field means that you can use the date selection tool in CRM to set the date. Or, better yet, you can add a date of birth field to the HubSpot form so that your contacts can publish their date of birth.5
Why did we add Next Birthday?
Our combination automatically calculates additional birthdays so that you can use them in Workflow, Lists, and Filters.
Age automatically updates*
Age is updated annually via HubSpot Workflow (available to Pro and Enterprise customers). The workflow will be activated when you announce (or update) your next birthday. And the workflow repeats every year, so you don’t have to worry about updating the contact’s age yearly for each reference.
* Automatic age renewal is available in HubSpot Marketing Pro / Creativity, Sales Pro / Enterprise, and Service Hub Pro / Enterprise.
Automating Age & Next Birthday Using HubSpot Workflows
To calculate age in HubSpot CRM and create a Next Birthday Workflow, you need:
| Custom Property | Field Type | Purpose |
| Date of Birth (Date) | Date Picker | Base date |
| Age | Number | Calculated annually |
| Next Birthday | Date | Trigger workflow |
Workflow Automation Setup
| Trigger | Action | Result |
| Birthday is known | Calculate age | Stores numeric value |
| Today = Next Birthday | Send email | Automated birthday message |
| Age changes | Update list | Smart segmentation |
What can we use your new HubSpot Addition for?
The potentials are endless; here are some applications.
Lists for Birthdays
You can filter contacts or create a wise list to keep track of everyone who has a birthday. A phone call or SMS is better than an email.
Lists for Ages Ranges
Because age is a numeric field, you can filter contacts and create lists where the communication is in a particular age group. For example, you can create a list of everyone aged 16-18 if your company targets a specific age group.
Workflows based on Birthdays
The most successful car dealer in the United States – Joe Girard – devotes its success to sending handwritten birthday cards to every customer every year (as well as on other holidays). It sounds kitschy now, but have you tried it yet?
You can implement automation in Marketing Pro, Sales Pro, or Service Hub Pro (depending on your configuration) based on the next anniversary of your contact. You have to surprise a new workflow with properties by date.
Workflows based on Contact Age
You can adjust the work procedures according to the age of your contact. For example, send a special offer when the communication reaches a certain age.
You can now send email offers of a specific age to Contacts, such as wine clubs.
