Moosend is an email marketing and marketing automation platform, formerly known as Sitecore Send. Besides campaign emails it offers landing pages, subscription forms, transactional email and an AI writing assistant. It is delivered as software as a service and also powers Sitecore's Send product.
The contracting entity is Moosend Ltd, with a registered office in London; the company was founded by a European team. Since June 2025 Moosend has belonged to Constant Contact, a US company owned by the private equity firm Clearlake Capital. This gives Moosend a US parent, which is relevant for CLOUD Act exposure. According to the vendor, customer contact data is hosted in the EU on Amazon Web Services; its data processing addendum lists AWS and Microsoft Azure locations in Ireland and Germany. Because the company is registered in the United Kingdom and has US owners, European organisations should assess jurisdiction as well as hosting location.
