A BirthdayBot alternative with a card the whole team signs
BirthdayBot is a Slack app that posts bot-written birthday and anniversary messages in your channels. The Moon Knows for teams opens a card a week before each day, everyone writes their own message from one link that works in any chat, and the card is delivered on the morning of the day.
Free for up to 5 people. Bigger teams get 30 days free, no payment details needed.

Questions
What people ask first
Is The Moon Knows a Slack app?
No. It is one link you paste into Slack or any other chat. When a card opens, we email you a message ready to paste.
Who writes the messages?
The team does. Each person writes their own message on the card, and each one becomes a star.
Can we try it before paying?
Yes. It is free for up to 5 people for as long as you like. Bigger teams get 30 days free with no payment details, and you choose a plan from your dashboard only if you want to keep going.
Do you store birth years?
No. We ask for the month and day only, and we refuse any birthday with a year in it. Start dates are only kept if you turn on work anniversaries.
