The scheme will be implemented in the coming weeks once the company’s share issue prospectus is published.
The TravelSupermarket mailshot is currently sent to around 300,000 subscribers.
The company refused to comment on widely reported valuations in the financial press – around £1 billion – for the MoneySupermarket.com business.
However, the company will continue its high profile TV advertising campaigns during the rest of 2007.
The current £9 million budget for the travel business – part of an overall spend of £16 million across the group – will be increased, managing director Chris Nixon confirmed.
Meanwhile, TravelSupermarket is to launch a videoblog service by the end of the year.
The blogs will be used to inform users of specific issues in the industry and discuss wider market trends.
TravelSupermarket specialists in hotels, airlines and holidays will be joined by other industry figures in the broadcasts.
