People who don't believe in god are more likely to achieve success at online dating, according to a new study of opening messages.
Self-effacing men are also more likely to get a reply to their approaches, while nothing turns off potential dates more than textspeak like "ur" and "luv".
The researchers analysed 500,000 "first contacts" sent by users of OkCupid, the leading US dating website, and found that nearly 42 per cent of messages, which included the word "atheist", received replies, significantly higher than the average response rate of 32 per cent.
The study also showed that references to "Christian", "Jewish" and "Muslim" only had a marginal success rate, reports the Telegraph.
Moreover, mentioning "god" in a first approach actually discouraged people from replying.
The research also suggests online daters to avoid making personal compliments too early like "sexy" and "beautiful", which reduced response rate.
It showed that people who used the words "good taste" or "you mention" in their messages pushed their response rates close to 50 per cent.
In addition, dreary greetings such as "hi", "hey" and "hello" are far less successful than sparkier openings like "how's it going" and "what's up".
The results of the analysis were published on OkTrends, the dating website's official blog.
