It would be nice if we could have a function where a system email went out to someone on their birthday. We could get that information from the member profile.
We just launched integration with Integromat platform, which helps to build automated workflows. We also provide several templates for quick start, and one of them allows to send birthday emails.
You can try the integration by this link https://www.integromat.com/en/integration/2274-happy-birthday-to-wild-apricot-members
