I saw my colleague wrote "Via our phone conversation earlier,...." in the email and was wondering if it is grammatically correct. And, What is the professional way to email someone to confirm the agreement after talking on the phone?
I come up with other ways to say but seems a bit diffuse.
1.After talking with you on the phone,... 2.According to our discussion via phone,... 3....
Can anyone teach me and give me more examples? Thanks.
