Build formal and business letters with proper formatting, date, addresses, salutation, and signature block.
A formal letter is a fixed sequence of blocks: the sender's address, the date, the recipient's full address, a salutation, the body, a closing, and a signature. This builder takes those parts as separate fields and assembles them in standard block format: everything flush left, blank line between blocks, no paragraph indents. What users most often get wrong is the inside address: it must be the recipient's complete postal address, not just a company name, because it is the sender's record of where the letter went, even when the letter travels by email.

Block order is sender, date, inside address, salutation, body, closing, signature, with one blank line between blocks and a three-line gap left for a handwritten signature above the typed name. The salutation and closing are emitted exactly as entered, so the letter keeps the tone the writer chose.
The form gathers the letter's components - sender name and address lines, recipient name, organization, and address lines, date, salutation, closing, and signer name and title - and orders them as block format requires: sender block, date, inside address, salutation, body, closing, signature. Each address is stacked one element per line, and every block is separated from the next by a blank line.
The builder places what you type; it does not rewrite it. An address entered without a state or ZIP stays that way, an empty field leaves a gap in its block, and a salutation like 'Dear John' is not corrected to 'Dear Mr. Doe:' or given a colon. Its guarantee is order and spacing, so the assembled letter should be proofread like any final draft.
The letter should carry the date it is mailed, because that date anchors deadlines such as payment terms and reply windows. A letter drafted today and sent next week should have the field updated at send time; leaving the draft date in place makes the letter read as stale before it arrives.
Yes, for formal letters. The inside address names the intended recipient and their organization on the letter itself, and it is how the letter is filed. Many businesses treat an email as the same record as a mailed letter, and a complete address makes that record unambiguous. It costs one line.
