How do I write a first line that gets replies?

Reference something specific (their post, role, or problem) and state a relevant outcome. Keep it under 20 words.

Examples of effective first lines:

• Referencing a recent post or comment
• Mentioning a shared connection or event
• Highlighting a specific pain point you can help solve
   

By starting with something that proves you’ve done your homework, you increase the chance of getting a reply and standing out from the many automated messages people receive.
