Hi BobGW,
Here's the problem: I don't want to spam them. How do I get these people interested in my weight loss hypnosis program (I could really help them) by sparking up a conversation and not spamming.
Well, regardless of your intention, you're still connecting with someone that didn't ask for your communication. Rather than think of it as spam, it's more appropriately cold-calling.
If someone cold calls you, how do you feel? Chances are that more most of the time you disregard because you feel like it is spam and non-value added. Try and find some cold call emails that you were attracted to - what made them effective? Can you adopt a principle they used to your own service?
Review your past clients that you've helped successfully - do they have friends that could use the same help? If you can get the validity of a friend, then reaching out to the next person won't be as difficult.
Try and focus on personalization - what about this individual makes you think you can help them? Have you helped similar people with the same problems and can express the result?
Keep it short and direct.
Relieve any pressure in the sales process. It's great that you provide a free 30min consultation, but that still scares people away. A lot of people feel like if they go in to see someone for a free consultation, they are still pressured into the sale. Attack that upfront (if you see it being an issue) and maybe point out that you don't allow a sales decision to be made at that point - i.e. after the free consultation you will reach back out to them and let them know they can be part of this program now that you've qualified them.
Use natural language and adapt your script to the individual. You'll quickly lose people if they feel like you are just blasting them another pitch message.
I hope these tips help, best of luck!
