Regional indicator letters, the building blocks behind flag emojis, as standalone custom emojis you can combine. On their own they are clean blue squares with letters; stacked together in a reaction bar they spell whatever you want, in the official emoji font no less.
These are the power user's letter tiles: same idea as Scrabble letters, different aesthetic. Spell names, acronyms, or short messages across a reaction bar. All 26 are free, and they render cleanly in Teams, Slack, and Discord pickers alike.
Upload the full set once and your workspace has a permanent alphabet for reactions. Naming each emoji after its letter keeps autocomplete sane in Teams and Slack. Word of warning: once people realize they can spell things in reactions, they will, and the general channel is never quite the same.
Download any emoji above, then upload it as a custom emoji in your workspace. Step-by-step guides: add custom emojis in Microsoft Teams, add custom emojis in Slack, or add custom emojis in Discord. If an upload is rejected, the emoji size limits guide lists each platform's limits and how to fix a file that is too big.
