The agency has been called in to help promote and help launch the charity's first-ever Christmas Jumper Day, which is calling upon the public to wear a festive jumper in exchange for a donation.
The activity is being supported by a number of the charity’s celebrity ambassadors, including Myleene Klass, Erin O’Connor and Ashley Jensen.
The agency will work alongside Save the Children’s in-house team on a brief that involves a media relations campaign with social media support.
The appointment comes after PRWeek revealed this summer that the charity's head of PR Sam Jones was leaving to join Amaze PR.
Jones, now a senior account director at the agency, said: 'Having worked within the Save the Children media team for 18 months the charity is very close to my heart, so I’m therefore thrilled to be working alongside it once again.'
Ann Bryon, head of PR at Save the Children, added: ‘We are launching the campaign at a very competitive time of the year, so we require additional resource from a consumer PR specialist to enable us to make the campaign as far-reaching as possible and help it launch with a bang.
'Having previously worked with Sam Jones, I was confident Amaze could deliver against this exciting and challenging brief.’
