Online dating website, OkCupid shared that
• 16% of all first messages are over 2000 characters, or about 400 words.
• First messages sent by guys are only half as likely to get a reply as ones sent from women.
• The average first message is 743 characters long.

Although longer messages will increase your chances of getting a response, you won’t be able to send as many. Read more here.

My question is: what about those who cut and paste their messages? They can send as many messages in the same amount of time.
