If I change the subject line …

Will it move to a new thread?

Notion Avatar

Changing the subject line in Gmail won’t necessarily create an entirely new thread.

  • Slight Change. If you make a minor change to the subject line (e.g., adding a “Re:” or changing a word), Gmail will likely keep the message in the same conversation thread.
  • Significant Change. A more drastic change to the subject line (e.g., removing all the original words and replacing them with something different) has a higher chance of causing Gmail to treat it as a new conversation. This will start a separate thread.

Gmail uses the subject line, along with other factors, to determine if emails are part of the same conversation.

If you absolutely need a new thread, change the subject line completely, or Start a new email.

If you don’t want a new thread, simply continue the conversation on the original thread.

Can I change it back?

And will that put it back to the original thread?

Notion Avatar

Unfortunately, changing the subject line back to the original won’t automatically put it back into the original thread.

Again, If maintaining an existing thread is important, Only make minor edits to the subject line.
