One of the most beloved Surefire features is Birthday Alerts.
To be alerted of your contact's birthdays, make sure you have the contact's date of birth filled out in the contact profile.
Next, turn on (or manage) birthday alerts go to: My Account > Notification Center
If you do not have any notifications the screen will be blank. Click on the gear in the top right corner.
After clicking the gear you will be presented with all of your notification options.
You will notice there are Email and in-app Notifications. Personally, I like to have both on.
You can turn on daily, or weekly - I like both.
Then click save!
You will now get both in-app Notifications and email notifications for Birthdays!
