Do you end your emails with “Best,” or “Cheers?”

"Sincerely” is probably the most common email sign-off out there.

But according to Peter Post, author of “Essential Manners for Men,” “Sincerely” has become all-purpose and safe and lacks sincerity. It also indicates there might be a problem. Here are some other closers – and how they come across:

• “Yours truly” is a safe bet and generic enough – but it leans personal.

• “Regards” is not bad – but it’s on the bland side and safe for professional stuff.

• “Best” is not really best. Save that – and variations of that – for someone you really know.

• “Cheers” is a popular one – but could come across to the reader as a bit “mock-Brit.” It also tends to conjur up the image of you with a drink in your hand.

• “Cordially” could have undertones of disdain – or convey that you’re super-serious.

Of course you could always opt out of the email closer and just end with your name – remember, that last word can be a valuable one and you might not want to waste it. It’s a great opportunity to leave the reader in sync with your intended tone – be it humorous, serious, urgent or casual. Get creative and come up with your very own - it will be remembered.

Seacrest, out.
