We just finished up a project with [Name of company/realtor], where we were able to get them <X benefits, depending on your service focus>.

This resulted in a <X%> increase in <leads, visibility, new listings, more buyers, faster sales, etc>.

I’d love to share with you how we did that, and how we could do the same for you.

If you think it makes sense to have a quick conversation to explore some ideas, just reply and let me know a couple of good times to give you a call.

Sincerely,

<Your Name>
