If you are using software like Sketch/Adobe XD/Invision, there are a variety of prototype and 'share' features that can allow you to present your work to clients easily.
Alternatively, it might be convenient to present mockups in PDF form. You'd want to present your designs in a uniform manner, with a nice layout (possibly including page number, your name/URL, etc). It's often useful to name the design options (Option A, Option B, etc) so that the client can easily communicate about each design.
