Here's the text we'd like to use for this year's automatic Thank You email. (Note: may need some formatting for the automatic fields -- [NAME], [GIFTAMOUNT], and the donation #, date and amount in the footer. Not sure what the proper syntax is!)

SL: Your donation ensures the future of Wikipedia. Thank you.

Dear [NAME],

I spent a lot of time thinking about how to express my gratitude for your $[GIFTAMOUNT] gift to the Wikimedia Endowment. You did something that so few people do – made a gift – and it’s important I tell you how special that is to us.

But in the end, I realized the best thing I could do is just say it: thanks, [NAME], from all of us at Wikipedia. Thank you for ensuring the future of free knowledge.

Today, thanks to the support of millions of volunteer editors and donors, you can wander Wikipedia for hours. With more than 50 million articles, Wikipedia can answer almost any question, and take you places you’ve never been. We started the Wikimedia Endowment to make sure future generations have access to Wikipedia like we do today, for years to come.

Your donation ensures that new generations will have this free gift of knowledge available at the touch of a button. There is no greater legacy you can leave to the future than knowledge of the present and the past.

The essential story of Wikipedia is the story of an individual, like you, giving a little bit of themselves to keep the doors of discovery open. Wikipedia will continue to evolve, grow, and meet new challenges because of because of generosity just like yours.

You helped us build this. And I'm committed to making sure Wikipedia is here for the long-term, for you.

[NAME], thank you for making sure Wikipedia has a bright future.

With gratitude,
Jimmy Wales
Wikipedia Founder
