They overlap: epistolary stories are told through documents like letters and journals, which can form a frame. But not all frames are epistolary—frames can be oral storytelling, interviews, or a narrator’s present-day commentary rather than a collection of documents.

Not automatically, but frames highlight the narrator’s role and perspective, which lets authors play with reliability. If the frame reveals bias, memory gaps, or motive, readers may question how accurately the inner story is presented.
