Question: I'm at a loss as to how I should title this. I have this sentence:

> 
> We have the option to provide notifications via 
>  telephone, and, possibly, email.
> 
> 
> 

I am trying to express several things:

1. We have an option to provide notifications
2. We can provide
those notifications via telephone
3. I think we can provide email
notifications (Further research is required, but I believe the
audience already has that context. The addition of "possibly" is
primarily meant to emphasize the lack of a guarantee).

Would I be better off with this:

> 
> We have the option to provide notifications via telephone, and possibly, email.
> 
> 
> 

or this:

> 
> We have the option to provide notifications via telephone and, possibly email.
> 
> 
>

Answer: 
I agree with Daniel, the commas are cluttering up your sentence unnecessarily.

You could consider:

> 
> We have the option to provide notifications via telephone and (possibly) email.
> 
> 
>
Oxford commas give me a headache. My feeling is that "possibly" does not need to be offset under these circumstances, therefore I would put "We have the option to provide notifications via telephone, and possibly via e-mail." 

However, I'm old, and still view the Oxford Comma as optional.
