InboxBirthdays

Birthday reminders that arrive in your inbox already paired with a written message are the core of InboxBirthdays.

The service is an AI message generator for birthdays: it creates a personalized message for each person on your list and emails it to you, so the reminder and the words to send come together.

It runs on OpenAI and GPT models.

The workflow is deliberately simple.

You get the email, copy the message, and paste it into whichever messenger you already use to talk to that person.

InboxBirthdays says this takes under 60 seconds, which suits people who remember a birthday at the last minute and still want to send more than a generic "happy birthday".

Because the messages land in your inbox, InboxBirthdays works as a light AI email assistant and writing helper rather than a full messaging app.

It does not send anything on your behalf, so the final step stays with you.

That is a plus if you want to tweak the wording before it goes out, and a small chore if you hoped for fully automatic greetings.
