Words such as one, it, its, it’s, him, and own should all be capitalized no matter where they appear in a title.

The phrase is not capitalized when used in a sentence. The words thank you were never meant to be capitalized on their own in a sentence, and any examples of it you see are likely just an honest mistake or the author’s own stylistic choice, but not a reflection of proper capitalization.

Thank You as Two Words As a verb phrase, “thank you” is always two words. Or to put it another way, you should always use two words for the act of thanking someone: Thank you for walking my dog. We can also use this term as a noun (i.e., something given as thanks):

Format your Closing “Thank you,” with only the first word capitalized, is a good choice if you are requesting something in the letter, like a meeting or paperwork. However, it is also acceptable to end a non-request letter with “Thank you,” according to the Colorado State University’s educational writing portal.

Select a brief, appropriate closing to end your letter. Additional options include “Sincerely,” “Respectfully” or “All the best,” followed by your first and last name and job title. You should include a space between the close and your name.

What you’re doing is fine, and it’s normal, and it doesn’t break any rules of modern business communication. In fact, as you’ve discovered, adhering to these rules every time could actually make you look weirdly formal or chilly in a lot of office environments.

Better Than ‘All The Best’?

1. Warmly.
2. Regards.
3. Warm regards.
4. Warmest regards.
5. Rgds (Shortened version of regards)
6. Stay tuned.
7. Stay tuned…
8. Cordially.

End with a thoughtful hope, wish, or sympathy expression. For example, you might include “You are in my thoughts” or “I will always be here to support you.” Avoid using the usual one-word endings, such as “Sincerely,” “Love,” or “Fondly,” which aren’t quite as personal.

His love endures forever.” Express your Christian joy in your own words. A sign-off need not be wordy and impressive. “Peace and joy,” “Thoughts, hugs and prayers” and “Wishing God’s best for you” are a few examples of informal Christian blessings you can write before your signature at the end of a letter to a friend.
