I can help you with adding user profile properties in Mixpanel. Based on the information provided, you're having trouble setting the $phone and $email profile properties. These are reserved profile properties in Mixpanel that have special handling.
Here's how to properly set these properties:
Setting Reserved Profile Properties
The $phone and $email are reserved profile properties in Mixpanel that are used for specific system features. They're particularly important if you want to use features like Cohort Syncs.
For $phone, note that international numbers need a '+' prefix. Without it, Mixpanel might add a country code based on the $country_code property, resulting in duplicate country codes.
Implementation Examples
Here are examples of how to set these properties in different SDKs:
JavaScript
// You must call identify first
mixpanel.identify('USER_ID');
mixpanel.people.set({
'$email': 'jane.doe@[example.com](http://example.com)',
'$phone': '+5555555555'
});
// You must call identify first
Mixpanel.mainInstance().identify(distinctId: "USER_ID")
Mixpanel.mainInstance().people.set(properties: [
"$email": "jane.doe@[example.com](http://example.com)",
"$phone": "+5555555555"
])
1. Make sure you're calling identify() before setting profile properties
2. Verify you're using the correct property names with the $ prefix
3. For phone numbers, ensure you're including the '+' for international numbers
4. Check that your implementation matches the SDK you're using
If you could share which SDK you're using and your current implementation code, I could provide more specific guidance.
