The Water Museum, an interactive museum that shows the history of water and the importance of this valuable resource, was opening its doors and we needed the majority of invited people to come to the inauguration.

For this, we designed an e-mail that showed its interactive feature: the text was inverted so that it could only be read by putting a glass of water in front of it.

From 5.000 people invited, 4.833 arrived. More than 80%.

Also, there was for two weeks a massive affluence of people that didn’t received the invitation but had some contact with the e-mail.
