This is so true for me - when someone emails, with only the two email addresses, it is NOT a referral to me. Email is easy to ignore.

This is what I do:

• In the body of the email I start the conversation by name, with one person, telling them why I am introducing them to the other.
• In the second paragraph I address the second person by name, and tell them why they will benefit from the first.
• Then I give both people's full names, phone numbers, I often repeat the email addresses, and I paste in the personal profile page link of the PowerCore Member (when it will reflect well on them!)

I want to be sure they have more than one way to connect - and I believe that if I introduce you to someone, and don't give you a way to reach them by voice, it's not an introduction. 
There are various modalities, and, as a business person, I need to be able to professionally use all of them.
I also believe that the person who will benefit (I could make a case for both people benefitting!) is the person who will reply first, by the most expedient method. 
I want to create benefit.

If I am doing an introduction in person, I will mention that I know the person personally.  I will forward them their contact information (or send a picture of their card) so they have everything they need to reach out.

I will then follow up with a three-way email introduction to both parties so they will be comfortable reaching out.

If it's strictly by email, a three-way email introduction is still the way I would go.

I always make contact with both parties before making the connection.  This way, both people are expecting and welcome the connection.  I usually give a personal piece or interesting piece of information about the Person I'm referring.   I want them to know it is someone that I KNOW, LIKE and TRUST. 

When I introduce someone to someone else, it is usually because I’ve heard a need in a conversation—either a direct referral opportunity or a potential gate opener.

I don't tend to make introductions just because two people happen to be in the same industry or because I have their names in my contacts. I want to have interacted with the person first and have a good understanding of what they do, how they work and, most importantly, how they could enhance the other person’s business.

Then, when I make the introduction, I can explain why I think the connection makes sense. I want both people to understand why I’m putting them together, rather than simply saying, “Hey, you two should meet.”

To me, a good introduction has a reason behind it. I’m putting my credibility behind both people, so I want to make sure there’s a real opportunity for the connection to be valuable.

I highlight to the prospect how a problem I learned about can be solved well by the PC member. For the PC member, I tell them about the problem the prospect is trying to solve. 

i mainly text each party separately with everyone's contact information and lean onto the referee that they should contact my guy. i used to be quicker on the draw because i really want to pass referrals so NOW i speak with the person who needs the service/product and verify that they are ready/desperate. people will drag their feet and forget without a little fire and i extend that bit to both sides.

One thing I’ve learned throughout my business journey is that every good sale or referral starts with understanding what someone needs. Recently, I sent six different three-way introduction emails because I knew each person had a need that the other could meet. I started each introduction with their names, explained what they do, and shared why I thought the connection could be valuable. I try to give enough context so neither person is left wondering why I connected them. After that, I let the conversation go where it goes.
