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 would say, you don't need a comma before "and" (although, you can use it; it's a matter of choice). But commas should surround "possibly". Hence, you can use:

> 
> * We have the option to provide notifications via telephone and, possibly, email.
> * We have the option to provide notifications via telephone, and, possibly, email.
> 
> 
>
Perhaps removing the first comma?

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

I've been taught that if a dependent clause is surrounded by commas it could theoretically be removed while leaving a syntactically correct, though not necessarily semantically equivalent, sentence.

or
