It allows advertisers to feature their product or service in The Preference Service's eNewsletter, a monthly email targeted to the stated interests of its consumer members.
The Preference Service will forward all leads to advertisers within 72 hours, and charge only for leads generated. The ad format consists of a colour image and approximately 40 words of copy.
Thomas Adalbert, managing director of The Preference Service, said: "Marketers will be able to contact an audience who have asked to hear from them, and therefore source hot leads, at exactly the time that consumer interest is highest because of the quick turnaround of data."
Once testing is complete around the end of the month, the company will reveal the media schedule of newsletters by topics such as travel, finance and days out.
The Preference Service already offers ad placement in its mail version, the Postal Preference Service survey.
