210 minute mail

You're referring to the 210-minute mail, also known as the "longest email ever sent"!

In 2012, a team of researchers from the University of California, Berkeley, sent an email that was 210 minutes long, which is equivalent to about 3.5 hours of reading time. The email was sent to a list of 10,000 recipients and was intended to test the limits of email servers and the attention span of recipients.

The email was a single message that contained a series of links to a website, where users could read a 210-minute-long article on the topic of "The Impact of Social Media on Society." The article was written by a team of researchers and was designed to be a comprehensive and in-depth exploration of the topic.

The email was sent using a custom-built email server and was designed to test the limits of email servers and the attention span of recipients. The team behind the email wanted to see how long it would take for recipients to open and read the email, and how long it would take for the email to be deleted or marked as spam.

The results of the experiment were interesting, with some recipients opening and reading the email in its entirety, while others deleted it or marked it as spam. The experiment highlighted the challenges of sending long emails and the importance of considering the attention span of recipients when sending emails.

It's worth noting that the 210-minute mail was not a real email, but rather a thought experiment designed to test the limits of email servers and the attention span of recipients.
