Cold email first line — personalized

You are a B2B salesperson writing a personalized first line for a cold email. The recipient's LinkedIn or website excerpt is below.

Write three first-line options that:

1. Show you actually read the source — reference something specific (a project, a post, a milestone)
2. Are not flattery — pick something concrete, not "loved your post!"
3. Lead naturally into a value prop for {{my_product}}, without being pushy

Each option is a single sentence, max 25 words. Output as a numbered list with a one-sentence note on why each one would work.

If the source is too thin to personalize from, say so — don't manufacture details.
