Remember that the more words you use, the more formal your sign off will be. Judge the formality based on the person to whom you are writing and their relationship to you.
“Sincerely” or “Thank You For Your Consideration” may be appropriate for job applications. Try “Continued Success” if you are looking to leave a partnership or correspondence for a while.
It’s a good idea to preload this onto your email program to save you time. Most companies have a standard signature that they like you to use.
“Ciao” can also be used for a playful end to an email. Remember that it may be seen as pretentious if the person doesn’t know you well enough to understand your tone.
