Using conversation threads is one of the most interesting features in emails, in this case in Gmail, as it keeps previous messages intact, allowing for proper tracking of the conversation (emails).

However, there may be times when we need to reply to or forward emails with a different subject while still staying within the same group or message chain. Changing the subject in Gmail is possible, though the feature is somewhat hidden.

When replying to an email, messages are grouped as threads when discussing the same subject line. It may happen that the topic or conversation mode changes, and we need to change the conversation’s subject. We need to respond because it’s necessary and has previous references, but at the same time, we want to edit the subject because the topic has shifted. In such cases, we can start a new thread with a new subject, which will also include old messages as previously cited responses.

How to change the subject line when replying in the same email thread in Gmail

Step 1: Open the email thread. Select ‘Reply‘ at the bottom of the email. A small window will open at the bottom of the screen for you to enter your response.

Step 2: Click on the ‘Down‘ arrow at the top left of the message box. A dropdown box will appear.

Step 3: Select ‘EDIT SUBJECT.’ A new Compose window will appear on the screen.

Step 4: Now, you can change the Subject as you wish and send it. The previous emails in the thread will be included with this email as well.

Important: Since Gmail organizes emails into conversation threads based on common subject lines, the recipient will now receive a new email with a new subject line but with a previous conversation.

You should also be aware that Gmail does not display subjects in conversation threads, so you will have to keep track of it manually.

You can also use these steps when responding to many people at once or forwarding the email. Just click ‘Reply to all’ or ‘Forward‘ and follow the same steps.
