Over one third of 2,000 people polled (34 percent) said they had ended a relationship by email, 13 percent had changed their status on Facebook without telling their partners and six percent had released the news unilaterally on Twitter.
By contrast, only two percent had broken up via a mobile phone text.
The rest had split up the old-fashioned way by face-to-face conversation (38 percent) and by telephone (eight percent).
"Digital Dumping will soon take over when it comes to ending a relationship," said Sean Wood, Marketing Manager for DateTheUk dating service for whom the survey was carried out.
"It's often easier, quicker and avoids any misunderstandings."
