Frequently asked questions
My caption was cut off on Threads. Why?
Threads allows 500 characters. Post Once keeps the first 500 characters of a longer caption, and the cut can land mid-word. Keep the important part at the start of your caption.
Does my Threads account need to be public or professional?
Post Once does not require a professional Threads account. Sign in with the account you want it to post to.
