Instinct PR is working with Savse's in-house team on the six-figure campaign, which asks consumers to tweet their Savse Promise to promote the brand and raise money for Magic Breakfast charity.
The brand has teamed up with nutritional coach Madeleine Shaw, who will be a brand ambassador and appear as a spokesperson for media, as well as host selected events and provide advice, recipes and tips.
Natasha Lytton, head of marketing and communications at Savse, said: "We are investing heavily in PR and Marketing for 2015, kicking off this week with the launch of our #MySavse Promise campaign - raising money for the fantastic charity Magic Breakfast - with lots more activity to be rolled out throughout the year."
Jonathan Kirkby, founder and director of Instinct PR, said: "We’ve worked with Savse for the last two years and the media coverage generated to date has been hugely successful at creating high awareness for the brand. Having Madeleine on board, and with all the additional activity planned, will continue to create even more noise for Savse and make them stand out amongst this competitive market."
