Sincerely: The Professional Email Closing That Means What It Says
'Sincerely' tells your recipient that you mean what you've written—it's genuine and honest. This closing has no hidden agenda or sarcasm. It strikes a formal but respectful tone that works across most professional relationships.
When to Use This Closing
Use 'Sincerely' when you're addressing someone you respect but don't know well, closing a formal letter, or ending communication about serious matters. It's your go-to for job applications, complaints, official requests, and first-time contact with clients or senior staff. It also works well when you want to sound thoughtful without being cold.
When Not to Use This Closing
Skip 'Sincerely' in casual team chats, replies to close colleagues, or informal internal emails where a simple 'Thanks' or 'Best' feels more natural. Don't use it for creative fields where personality should show, or when you're responding to someone who already used a warmer closing. Avoid it if your message is brief or lighthearted—it can feel overdressed for the occasion.

Pair 'Sincerely' with a professional email signature that includes your full name, title, phone number, and website. The formality of your closing deserves equally polished contact details—this is exactly what your signature should deliver.
