Customize Billy's celebration messages and GIFs

Replace the closing line of a Billy birthday or work anniversary post with your own words, or pick another GIF, for one posting day in one Slack channel.

SlackUpdated Oct 5, 20262 min read

In Slack, Billy admins can replace the closing line of a Billy celebration with their own text, and swap the GIF, for any upcoming day. The rest of the message (the intro and the list of people) stays the same.

A customization applies to one channel and one posting day: every celebration posted that day in that channel. It isn't available in Microsoft Teams.

Step 1: Click Customize messages#

In the admin settings, click ✍️ Customize messages. The button shows once Billy is in at least one channel.

Step 3: Click Edit message#

Upcoming celebrations lists the next 365 days, grouped by posting day, 20 at a time (use Next ➡️ and ⬅️ Previous). Click ✍️ Edit message next to the day you want to change.

  • Message: replaces Billy's random closing line. The hint in the window says it's "appended", but it actually replaces the closing line. It's posted as plain text: Slack formatting and @mentions aren't applied.
  • GIF: paste a direct link to a GIF. Billy posts it even if GIFs are turned off for the channel.

Remove a customization#

Click 🗑️ Delete customization next to the day, then confirm.
