Email requesting information

Dear Sir/Madam,

I am writing to enquire about the online courses that you offer. In particular, I am interested in the B1 English course and I would be grateful if you could provide some further information.

I would appreciate it if you could tell me how much the course costs and when it will start and finish. I would also like to know about the kind of activities it includes and if there will be an exam at the end. Could you send me a detailed programme with the contents of the course?

Finally, I would like to know if you will provide a certificate indicating the number of hours.

I look forward to hearing from you. 

Yours faithfully,

Mary Smith
