The email composer/reply pane is too small.
FinAI acknowledges that, as of Feb 2026, “The email composer in Intercom doesn't have a built-in option to resize or make the composition pane larger within a thread. The composer size is fixed in the interface.”
It is especially limiting if you add screenshots, or have a long reply to review before sending to a customer.
It would be more helpful if you could do a pop-out window for composing an email reply to a thread, thanks.
