A project manager ends her client update with "Warmly, Jessica." The client smiles and replies the same day. Her colleague ends a similar update with "Later" and hears nothing back for a week. The body of both emails was fine. The sign-off set a completely different expectation.
Email sign-offs are the closing words that appear between your final paragraph and your name. They signal the tone of the message and leave a last impression on the reader. The right sign-off depends on your relationship with the reader, the formality of the message, and what you are asking them to do. Here are sign-offs that work across common business situations.
What is an email sign-off?
An email sign-off is a brief courtesy phrase that closes your message before your name and signature. It is not the same as the closing line in the body, which states your call to action. The sign-off is the social layer. It says the conversation is complete and you respect the reader.
Common sign-offs include Best regards, Thanks, Sincerely, and Kind regards. Each carries a slightly different tone. Choosing the right one takes seconds and affects how your message lands.
