Only include attachment info fields if they actually exist, this was including empty strings
Change alternative-format request copy, per request. Strip whitespace on the email, as some have trailing space and it messes with the copy punctutation

* original format that wasn't asuitable
* ask for more details of why it wasn't suitable and what would be better - should avoid some back and forth with requester
