What is the difference between “besprochen” and “gesprochen”?

Question

What is the difference in meaning between these two sentences and which one is correct for a formal e-mail?

• Wie besprochen sende ich Ihnen meine E-Mail Adresse.
• Wie gesprochen sende ich Ihnen meine E-Mail Adresse.

(We had talked on the telephone, if that makes any difference.)

Answer 1

Wie besprochen ...

is the correct one.

Wie gesprochen ...

doesn't make sense.

"Sprechen", of which "gesprochen" is a form, focusses more on the act of speaking. "Besprechen" focusses on the topics that are spoken about.

Answer 2

It's two different words: besprochen is the past participle of besprechen (discuss, talk about); gesprochen is the past participle of sprechen (speak, talk).
