That all depends on the tone and purpose of the letter.
Some common closings for formal letters are:
Sincerely,
Respectfully,
With regards,
Personal letters may want to use:
Sincerely yours,
Love,
Your friend,
Your loving _________,
======================
How about:
I remain, your most humble, loyal and obedient servant, etc., etc..
But I prefer, for business letters simply:
Yours truly,
Yours very truly,
And by the way, again for business letters, I prefer to begin each letter with a 'Re:' line, referencing the matter about which I am writing in a few words. I also prefer to introduce the body of each letter with a one- or two-sentence paragraph clearly and succinctly outlining the reason for my letter.
===========================
My favorite is:
All The Best,
Respectfully yours
wedding cards salutations
Eat well and be marry, Christmas that is. Have a wonderful holiday
Salutations, dear friend.
A warm closing for a letter is the term Regards or Warm wishes. A warm salutation is My dearest followed by the name.
The closing salutations vary depending on the time of the church year or season. Most commonly, the pastor dismisses the congregation with peaceful wishes and the congregation will praise God in some form as their response.
That's funny, because I'm writing some right now! I'm putting "Have a Happy New Year." However, you can also write something along the lines of: "Have a happy 2013" "Have a great New Year" or simply "Happy New Year"
Memos, complaints, and sales letters are all types of business letters. Business letter use formal salutations compared to other types of letters.
Business letters generally use Yours Sincerely or Your Truly when closing.
Here are some: In Him, In Christ, In Jesus' Joy, Many Blessings, In His Service,
Salutations is just a fancy way of saying, "Hello"
The opening and closing salutations for an email should use exactly the same criteria as other mail. It depends on the formality of the mail and to whom it is addressed.
