Dear Sir/Madam,
I would like to apply for the job as stated above. Though I do not have experience with paid copywriting, I have done small projects in the past for free for my friends.
Furthermore, I am a native English speaker, having studied English Language and Literature in high school under the IB Diploma program and I feel that the course equipped me with skills necessary to write an effective copy. In the course, I analyzed advertisements, brochures, newsletters etc, and from there, I believed that I understand the nuances of the English language to produce a compelling piece of work.
Because I do not have paid copy writing work, you can be assured that I am open to criticism, a hard worker and would do my best to produce quality work.
