The Daily Mail says tens of thousands of consumers have signed up to MailTxt since it launched the platform earlier this year to build a more interactive relationship with its readers.
MailTxt is free and there are no subscription charges or commitments when using the service. It works by connecting a mobile phone to the internet momentarily, while sending and receiving MailTxts.
Sending and receiving a MailTxt from one registered user to another is free except for a 1.4p connection charge, applied by the networks.
The Mail said that sending an SMS via MailTxt from a registered user to a non-registered user is also significantly less expensive than other mobile operators, costing just 6.4p.
The service also offers a 0.5p MailTxt credit for every message sent and received via a subscriber's phone, access to Daily Mail main headlines and stories each day and the chance to participate in topical weekly polls.
Guy Zitter, group director of Daily Mail Group, said: "We are delighted that this ground-breaking and tech-savvy venture has been such a hit with our readers. It shows how highly adaptable our loyal consumers are to innovative services of this kind."
