A new email platform will be brought in to replace BT Yahoo! Mail as the broadband provider gives its online services a facelift.
BT is planning some major changes to the online services it offers broadband customers.
As part of a massive revamp, BT broadband customer email accounts will be switched to a new platform called BT Mail, replacing the current BT Yahoo! Mail service.
BT Mail will be accessed through BT's website (BT.com), which is currently in the process of having a makeover.
The relaunched site will make email and a range of other services, as well as customer account and billing information, available with a single login.
Nick Wong, BT's head of online customer services, said: "The new BT.com has been developed to make things easier and more engaging for our customers. They will only have to log in to this single site for all their requirements.
"Our new website will feature breaking and exclusive news and features from a dedicated team of journalists at the Press Association covering areas such as news, entertainment and lifestyle."
During the summer, the BT Yahoo! Mail platform will close to new customers, but existing users will still be able to access their account through BT's website.
Later in the year, customers will be switched to the BT Mail service. Their email account, including all saved messages and folders they have created, will be migrated. Although customers will keep the same email address, a new password may be required.
BT's decision to drop Yahoo! Mail follows numerous reports in recent months of the service being hacked by cybercriminals.
In April, Yahoo! Mail replaced the Sky customer email platform, which had previously been powered by Google Mail.
