Generally, using inspirational phrases or quotes as a part of the sign-off in a business email is not recommended. Although they might seem like a good way to create a long-lasting impression on the reader, they can still appear insincere and unprofessional. That’s why you should stick to a more standard sign-off, such as “Sincerely” or “Best Regards”, since they convey professionalism and respect. Another important factor you should remember while ending the business email is to prioritize simplicity over creativity. Normally, most recipients are busy and might not have time to read a quote or an inspirational phrase. On the contrary, you can use email signatures or business cards to provide important information about the business and yourself.
