Have you ever been in a long email chain on Gmail? Sometimes the back and forth messaging goes on for what feels like forever. And sometimes the correspondence is so long that the subject or the topic of the conversation changes entirely.
If you’re wondering how to change the subject line in Gmail Reply, you’re in the right place. This option isn’t known to everyone, mostly because it’s tucked away pretty deep in Gmail settings. Don’t worry, though, we’ll shed some light on it and help you easily change the subject line and avoid any possible confusion.
How to Change the Subject Line in Gmail Web Version
Changing the subject line isn’t that difficult, but this option escapes the eye of most people. If Google is trying to make some of its Gmail settings, like this one, more transparent. Until that happens, you can follow these instructions to change the subject line:
- Log into your Gmail account. Here is a direct link  you can use to log in.
- Open the email conversation for which you want the subject line altered.
- Click on Reply at the bottom-left corner of the screen.
- A new window will appear. Click on the arrow (pointing down) in the top-left corner of this window.
- Click on Edit subject from the dropdown menu.
- A new message window will appear. The Subject Line will be selected, and you can freely edit it. Change it to something you’ve had in mind.
- When you’re done editing, click on Send at the bottom of the page.
Your previous correspondence in this thread will be saved, and all the previous messages will be quoted. However, the new subject line will appear. To make things clearer, you may inform the recipients about the change and why you decided to go for it.
Oh, and note that you can use the same steps to change the subject line even if you decide to select Forward, or Reply All in Step 5 of the guide above.
How to Change Subject Line in Gmail Mobile
These instructions only apply to the web version of Gmail. The steps are a bit different if you’re using the mobile app. The app is free, and you can use these official download links for Android  and iOS  devices to either download or update the app to the latest version, which is very important.
Make sure that your mobile or tablet has the latest system updates, and that you’re using the latest version of the Gmail app. When you’re ready, and you have a stable Wi-Fi connection, follow the instructions to change the subject line in the Gmail app:
- Open the Gmail app on your Android or iOS mobile device (tablet or phone).
- Open the email conversation which needs the subject line changed.
- Click on Reply at the bottom part of the screen.
- The subject line will be ready to edit by default. Tap on it, delete the current subject line and type out a new one.
- That’s it, the change will be saved automatically, there’s no need to do anything else.
As you can see, changing the subject line is much easier in the Gmail app for mobile devices. Hopefully, Google will implement this method in the web version as well. This would be welcomed by all the people who still use the web version, myself included.
Change the Topic!
No matter if you’re using Gmail for work, school, or just casual chatting, you know that some conversations go back and forth seemingly endlessly. You can end up having a conversation about something entirely different. Therefore, the old subject line will appear redundant, or even worse, cause confusion.
There’s no need to add further uncertainty to an already out-of-hand email chain. Put a stop to it, change the subject line. If you’re using the web version of Gmail, then I can understand why this seemed all but impossible.
