How do I write a “custom letter” in response to an anonymous ad?
Do the best you can. Occasionally you will encounter classified advertisements that only provide a PO Box address, with no company name and/or limited information about the company. While this makes it more difficult to tailor a cover letter, use the few clues they provide and give it your best attempt. Some pointers: Address the letter to “Dear Human Resource Director (or Manager)” instead of “Dear Sir/Madam” or “To whom it may concern”. Make some basic assumptions about the company and use your picture to address the position. If you think you know what company it is, call and ask if they are hiring for the position.
