Why is writing a prospecting letter more challenging than a solicited letter when sending a résumé?

A) You have less research on the company
B) You don't know what skills the company is most interested in
C) You don't have a clear target as you have with a solicited letter
D) It is hard to find the name of a person to send the letter to
E) You have no common ground with the reader

A prospecting letter is unsolicited, meaning you are reaching out to a company without a specific job opening in mind. Therefore, it is more challenging to tailor your letter to a specific target since you do not have a clear idea of what skills or qualifications the company is looking for. A solicited letter, on the other hand, is in response to a job posting and you can tailor your letter to the specific qualifications listed in the job description.
