Hi {First Name}

I have a business idea to help {Their Company Name} enhance its {profitability} (or insert thing you can help them with).

This same concept has helped other businesses such as {Client X} (works best if they would know the client you mention) improve their profitability by {X} in the last {6 months} (a specific example here works best).

When do you have 10 minutes to hear my idea and see if it can work like it did for {Client X}?
(we recommend including a link to you appointment booking app here).

Thanks,

{Your name}
