Despite the proliferation of online communication methods, email remains the most popular, with nearly 300 billion emails sent each day in 2019. Whether you're brand new to email or have been using it for decades, make sure you follow the rules of email etiquette.

Once you've entered your recipients' addresses, come up with an appropriate subject, written your message, and attached some supporting documents, go back and check that you did everything correctly:

You need to know when to Reply All and when not to Reply All on group emails. If everyone in the original email (the one you're replying to) needs to know what you have to say, use Reply All.

For example, person A emails you and person B to brainstorm ideas on how to celebrate your boss's 10th anniversary at the company. Your response is relevant to both person A and person B, so use Reply All to respond to both.
