How to contact sponsors?
Simply send them an email like this:
My name is X X and I am the organizer of Django Girls in City. Django Girls is a global, non-profit organization that helps women to get involved with technology and teach them about programming.
We're doing our first event in City on X the Xth and we would love to get you involved. We're looking for sponsors who can help us cover the costs of food, drinks and others.
Attached is our sponsorship proposal, but we would love to talk to you more. Please get in touch.
Have a great day, X X
