Mail adapter scenario

Hi everyone.

I've discovered how to send an email, but i didn't know how to do some more things.

First, i would like to send an email to the address that comes in a field of the payload.

Second. i would like to attach a csv file but i don't know how to do that because the only way i know to create a csv is through file adapter with content conversion.

Third. In the content of the email must be included a text like 'Dear Sir. Your file has been processed correctly'

Can anybody help me with this?

Thanks.
