The structure that works
Greeting → who you are → why you wrote → one shared interest → one easy question → warm closing.
Copy-ready template
“Hi, I’m [name] from [place]. I love [interest]. I wrote because your profile mentioned [detail]. What’s a small joy in your week? Looking forward to slow letters with you.”
What to avoid
Avoid walls of text, interviews with ten questions, romance pressure, or asking for socials too early.
After they reply
Mirror their energy, answer their questions, and add one new thread. Consistency beats perfection.
FAQ
How long should the first letter be?
