Thou shalt THANK the person who made the introduction post-meeting- Likely the introduction that was made for you helped in some way. You either got some business out of it, made a few good connections or just had a great time. The person who made the introduction is always interested in hearing how things went and we all enjoy being thanked. Make sure that is part of your follow up activity. It need not be long or involved, just heartfelt.
Thou shalt close the loop on the introduction- This can be done in the thank you or post-thank you, but it is really important to let the person who did the introduction know how things went. This includes the good and the bad. If someone is a service provider, you may want to find out how the service was before making future introductions. It's important to know what happened post meeting and the more closing of the loop you do, the more the other party will appreciate it.
Thou shalt NOT drop off the face of the earth post meeting- Life gets crazy and we often get busy, but if you said you'd make some intros for someone, you should always make sure those intros get made. If you told someone you'd send them website links or other information, make sure to send it. Nothing is worse than having a great meeting and then never hearing from the person again. Stay in touch.
and the final commandment:
Thou shalt always keep those who introduced you in mind- If someone made a great introduction for you, then you want to always be thinking of a good introduction for them. Pay close attention to their industry and think proactively about how you can help and what you can do.
So there you have it. If you follow the 10 commandments, not only will you have built a great network from your email introductions, but it will be a network that will help you for years to come.
