How to Change Subject Line in Gmail

The steps in this article are going to show you how to change the subject line in Gmail for an email to which you are replying.

  • When you edit subject lines in Gmail you are able to create your own new subject line for an email that was sent to you. This can be helpful in some situations, but it can also make it tough in the future to follow a conversation thread.
  • Changing the email subject line allows you to remove the Re: part of the message that appears before the original subject line.
  • Consider starting a new conversation thread instead if you are changing the subject line in Gmail because you are starting a new topic of conversation.

Google’s Gmail email service includes many of the features that you will find in paid email applications like Microsoft Outlook. Among these features is the ability to edit most of the information that appears in emails that you send and receive.

But if you have an email conversation in your Gmail account that has already been started, and you want to change the subject line of that conversation without creating a new message, then you may be struggling to do so.

While it may not seem like the subject line is editable when you are working with Gmail in your Web browser, there is actually a way to change the subject line in Gmail. Our tutorial below will show you how.
