Do these two sentences diagram out unambiguously and nicely?

I would better use the following, "A few / Two hours later, I received the following reply:...."

Thanks! I appreciate the response!

I wonder, though, whether the two sentences actually do diagram out unambiguously and nicely; do you know whether that's the case?

Thanks so much!

I see no ambiguity here, but what do you mean by 'diagraming out'? Do you mean there is harmony between them?

I mean that the sentences can only be diagrammed one way so that there's zero syntactic ambiguity; does that make sense?

As I've just said, ''I see no ambiguity here.''

Hi, Andrew—What is it about your two sentences that makes you think there may be some syntactic ambiguity involved?

The em-dash constructions made me worry about ambiguity, but were my worries unfounded? I hope that my worries were unfounded!

The em-dashes here function like emphatic commas or parentheses. The material they contain specifies the time of the e-mail and the response, respectively. It cannot be read in any other way. Thus, there is no ambiguity.
