Communicator, which is part of the Alterian marketing services platform, creates and distributes marketing content, optimising a brand's marketing operation by allowing it to be managed centrally.
The software will connect all parties involved in One&Only's global marketing operation, including its central brand team and sales office in North America and its sales offices in the UK, France, Germany and Russia.
One&Only will be able to centrally manage all of its digital media assets and create an automated email news update.
Future phases of the service include extending the built-in content management tools to allow local resort marketers to publish special offers, based on availability, aimed at specific tour operators.
Jenny Naylor, brand communications director of One&Only, said, "As custodian of a very valuable luxury brand, it is essential that One&Only can easily and correctly apply its brand across all marketing activities around the world and ensure internal communication processes are as efficient as possible.
"With Communicator we're able to deliver brand and marketing information effectively across all our channels and interact quickly with all stakeholders."
One&Only runs six luxury resorts in the Bahamas, Dubai, the Maldives, Mauritius and Mexico.
