When to Create a New Email vs. Reply

• If you receive an email from a colleague (email originator), reply/reply all to this email thread on the topic.
• If you are providing relevant  information to the existing email thread, do not start a new email chain.
• Don't take over an email thread on one topic to discuss another topic. Start a new email thread instead, with the relevant subject line and recipients.

When to Reply vs. Reply All

When deciding between Reply and Reply All, ask yourself a series of questions:

• Is the email addressed to me?
• Does more than one person need to know the email was responded to?
• Will the other recipients be confused if they don't see me respond?
• Does the email impact 70% of people on the chain?
• Do the others need to remain on the chain?

Reply All is helpful when you're on an email chain full of people working together on a project. Everyone has access to the same information, and you can see comments and updated in real time.
