If you are speaking to any clients this week regarding mortgages, copy and paste this email. Interest rates are in the 2.5 to 2.75 range. That’s no guarantee as each situation’s different, but a good range to use when running numbers. 
Feel free to make an email introduction. I am happy to be a resource.  Below is an email you can copy & paste to suggest making an introduction.

Dear Client,

How are you?

Mortgage rates have staged a nice rally recently. There may be an opportunity to refinance and save some money. Many times this can be done with NO COST. Please let me know if you are interested in this timely opportunity, and I will refer you to my Core7 Mortgage Originator who specializes in Mortgage Management.

Thank you
