"Hi! Sorry for the late reply. Just seeing this now. Happy to help if you're still looking. Feel free to DM me!"
A local plumber replying to a customer who needs help today.
- Replying hours later — the customer has already found someone.
- Writing from scratch — every comment takes time to think through.
- Generic response — "DM me" doesn't answer their actual question.
- Missed opportunity — you saw the post, but couldn't respond fast enough.
Result: more time writing, less time engaging — and fewer chances to win the customer.
