I want to schedule an appointment at the dentist's. I read that "erreichbar sein" means "to be reachable" and you can use it when you talk over the phone, but I was wondering if I can say it instead of the phrase: "I'm available." Can I write something like this?
Guten Tag Herr Miller,

Ich freue mich auf Ihre Antwort.
My question is similar to the one I've already asked:How to say "I am available.." in German? (scheduling an appointment)
but I want to understand the difference between them and how to use them.
