The Electoral Commission is hailing its text message reminder campaign - on the day of last year's general election - as a success.
In a controlled experiment, those who received a text message on 8 November reminding them to vote, had a 4.7% higher turnout than those who did not get it.
The commission says the impact of such a direct marketing initiative is large, and the initiative is an effective and cost efficient way of prompting people to vote.
It says a large-scale texting campaign could be particularly effective at motivating the commission's "priority audience" of young people.
