Launched by Match.com in February 2006, Chemistry.com was created to bring together independent-thinking, confident, diverse singles that are serious about finding a meaningful relationship. Based on the research of renowned biological anthropologist Dr. Helen Fisher, Chemistry.com is dedicated to helping our members start the conversation to determine if there’s Chemistry.

Here’s how they do it: 1. Members get to know their matches long before they meet each other, plus the site gives fun and unique activities to flirt and discover more about each other. 2. Chemistry.com reveals upfront what our members have in common with each other. 3. Chemistry.com gives insight and advice about each member’s personality type and the personality type of his/her matches. 4. Online coaching materials show our members how to write more effective emails, then share tips on making their first date as successful as possible once they are ready to meet.

The 3-for-1 (3 months for the price of 1) promotion going on now is a pretty good deal, if this sounds interesting to you now is a good time to try it out.

The free membership allows you to post your profile and search members, as well as send winks and flirt. However you need to upgrade to a paid membership in order to message other members. Paid memberships also have higher priority in search results and customer support.
