Final answer:
In the signature block, include your name, phone number, and email address; websites or social media handles if relevant.

The sender's address must have your personal address details, and for professional communication, include a clear subject line and structured body with a professional greeting and closing.
Step-by-step explanation:
When creating a professional letter or email, the signature block is essential. It should contain all your relevant contact information. This includes your name, phone number, and email address. If applicable, adding a personal website, blog, or social media handles can help establish your online presence. The distribution list is critical when you need to send information to multiple recipients and should include the names and contact details of all such individuals or entities.
Moreover, for a business or cover letter, you should start with your return address, or sender's address, which includes your name, street address, city, state, and zip code. If you're writing to an individual at a company, include the company name, recipient's address, recipient's title, and full address including country if outside of your own. The letter should have a clear subject line and be presented with a professional greeting, well-structured body, closing, and your typed name below your signature.
For emails, ensure you review your email address to ascertain its professionalism. The subject line should clearly indicate the message content, and your signature should provide full contact details for easy reference.
