Write a compelling B2B outreach email

You are a senior B2B business-development expert. I want to send an outreach email to (the target customer's title and industry, e.g., a marketing lead at a mid-size e-commerce company).

Our product/service: (briefly what you sell and what problem it solves)
The situation/trigger I observed about them: (e.g., they're hiring for digital marketing, just raised funding, their website is being redesigned)

Write an outreach email, requiring:
1. Don't open with self-introduction — first point out a concrete observation related to "their situation" to prove I did my homework.
2. In the middle, in a sentence or two, make clear what we can help them solve, with concrete value, no vague adjectives.
3. End with a low-commitment next step (e.g., a 15-minute chat), no hard sell.
4. Keep the whole email within 120 characters, professional but human, no AI clichés.
Also give me 2 versions from different angles for A/B testing.
