seven is a German provider of messaging and communication APIs. Its offering covers sending and receiving SMS, an SMS gateway (API, email-to-SMS and SMPP), voice messages with text-to-speech, RCS and SIM hosting. It also provides number validation services such as HLR, CNAM and MNP lookups. Users can work through a web application, the API or a command-line tool, and integrations exist for tools such as Zapier, Slack, HubSpot, WooCommerce and Node-RED. Use cases highlighted by the company include appointment reminders, alerting and two-factor authentication.
seven describes itself as "Made in Germany", with the footer pointing to Kiel. According to the company's help centre, its servers are located exclusively in Germany and data is stored in a German data centre. The company states that it holds an ISO/IEC 27001:2022 certificate covering development and operation of the platform. The website names no foreign parent company, and the software is not open source. For a European organisation this means a service hosted within the EU; the pages consulted do not name the data centre operator.
