"Hi" or "Mr./Miss. Name" can be used instead of dear.

The alternative way to address a formal letter when the recipient's gender is unknown is to use "To whom it may concern" instead of "Dear sir/madam."
Dear
Yes, it is correct to use a capital letter after the comma in "Dear Sir" as it is used as a salutation at the beginning of a letter or email.
Use the name of the person who wrote the letter, and write a formal letter. Use the salutation "Dear Mr. ____" or "Dear Mrs. _____" as a salutation.
The alternative to addressing a formal letter to "Dear Sirs" is to use "Dear Madam or Sir" or "To Whom It May Concern."
It is not recommended that a writer use "Dear Gentlemen's" in a salutation. "Dear gentlemen's" is referring to the gentlemen's object, not the men themselves. Try using "Dear gentlemen" instead.
You would normally capitalize nouns in the salutation, Dear Residents: (but this is not a significant aspect of the letter and is often ignored). If you use a longer salutation, such as "My dear Neighbors," the word dear would not be capitalized.

"Dear" is what people use it nowadays.
"Dear Sir," is all you need to use.
