A formal invitation letter can be completed in the business style block format. Include all of the information that would be printed on a standard invitation, the date, time, and location of the event along with an explanation of how formal the event will be, casual, business attire, formal, etc. Be sure to include the information for the recipient to follow up, the senders phone number and address. Do not include an email address as email is not appropriate for a formal invitation. A return note with a postage paid envelope for the recipient to respond such as is included with formal printed invitations can be included.
A formal or causal letter is usually mailed in an envelope.
Address on envelope to a doctor: Dr. John Doe is the general form.

An Application letter is written by a job seeker. It should be formal and interesting to attract the attention and interest of the recipient to warrant at least an interview. The application letter should contain relevant information about the applicant for the recipient to make a better consideration on his application.
In English, the sender's address goes at the top right of the page. The recipient's address goes at the left of the page, starting directly opposite the position of the date, under the sender's address.
Yes, in a sense that an application letter is written by a job seeker. It should be formal and interesting to attract the attention and interest of the recipient to warrant at least an interview. The application letter should contain relevant information about the applicant for the recipient to make a better consideration on his application.
The envelope should read: Mr. John Doe & Dr. Jane Doe. If you don't know her first name then put: Mr. & Dr. John Doe.
Recipient title refers to the formal title used when addressing or referring to the recipient of a communication or service, such as Mr., Mrs., Dr., or Prof. It is used as a sign of respect and can vary based on the individual's gender or professional status.
I think in this case formal is better. A formal invite would not be sent through an email. Social etiquette would say deliver via snail mail because you are showing the recipient that you are taking the time out to make sure they receive something.
A formal letter has the sender's address and the date in the upper right corner, unless it is written on letterhead. Below that, on the left side, it has the recipient's address.
