- An illumy subject line can be 100 letters or symbols maximum.

- The illumy message can be 10,000 letters or symbols maximum.


When you write a message on the illumy app, the subject line can’t be more than 100 letters or symbols long, and the message can’t be more than 10,000 letters or symbols long.


These limits help you keep your messages short and clear for others, as very long subject lines or messages can be hard to read or follow. By having these limits, the app can make sure everyone has a good experience and avoid any problems that may happen from very long messages.
