Hey, {{name}}!

I’m a huge fan of {{their blog}}. I just wanted to reach out because I’ve really been enjoying your writing. In fact, I accomplished {{something cool}} from reading your blog post: {{link to their blog post}}.

I know you’re busy, so I won’t waste your time. I’m reaching out because I had some ideas I think the {{their blog name}} audience would positively love, and I was wondering if you’d be open to a guest blog post.

Here are the titles:
{{Title 1}}
{{Title 2}}
{{Title 3}}

To give you an idea of my writing style, here are two of my best posts:
{{Your post with the most shares}}
{{Your best-written post}}

Thanks for your time and consideration! I can’t wait to hear back from you.

Cheers,
{{Your name}}
