What actually matters when closing clients from cold outreach?

Would you add anything to this list or disagree with any points? What actually matters when closing clients from cold outreach:

1.
Sell to people with money and pain who you can get results for. That’s your ICP.
2.
Build a strong offer meant for cold traffic. “We’ll get you {{outcome}} in {{timeframe}} by doing {{unique mech}} - {{guarantee}}”
3.
Guarantee something as close to sales and revenue as possible. Never guarantee deliverables or activity. If you don’t trust you can get results for your clients, why should the prospect?
4.
Be expensive. With a proper ICP and outcome guarantee you can charge more.
5.
Volume.
6.
Reply to leads within 1 minute.
7.
If someone shows interest and then ghosts, reach out to other people at the same company.(This has booked us loads of calls and it’s easy.)
