How to add subject lines to texts in the Messages app

Text Message Subject Line iPhone

We’re all used to subject lines in emails. That single line of text lets you know what the email is about. But did you know that you can use subject lines in the Messages app on your iPhone and iPad too?

Adding a subject line to a text message can be used for the same purpose as it is in an email. While it might not be something you use when texting with your best friend 50 times per day, it could be useful when sending text messages for business purposes.

In addition, the subject line in a text in the Messages app automatically bolds the text for that line. So, you can also use it to make specific text stand out.

If this sounds like something you’d like to start using, here’s how to add subject lines to texts in the Messages app.

Enable and use the text message subject field

To enable this feature in the Messages app, open your Settings and then do the following.

1) Scroll to and select Messages.

2) Under SMS/MMS, turn on the toggle for Show Subject Field.
