There are a few things you can do to proofread your text messages before sending them. First, make sure to use proper punctuation. This will help to ensure that your meaning is clear and that there are no misunderstandings. Second, take a break after writing the message before proofreading it. This will allow you to come back to it with fresh eyes and catch any errors you may have missed the first time around. Finally, read the message out loud before sending it. If these steps are too much, you can always rely on the spell checker from Android or Apple!
