German SMS gateway and business messaging platform, pay-as-you-go across 880+ networks
European email & communication alternative based in Germany.
What seven.io does
seven.io (formerly sms77.io) is a Kiel-based SMS gateway and business messaging platform founded in 2003. It handles SMS sending and receiving, voice calls, text-to-speech, and number validation across 880+ mobile networks globally, positioning itself as a full-service messaging provider for European businesses.
Capabilities
Messages can be dispatched via API, the web application, email-to-SMS, or dedicated phone numbers. The platform supports two-way SMS, HLR lookups for cleaning contact lists, and pre-built integrations with Zapier, Slack, WordPress, Shopware, and Magento. Common use cases include two-factor authentication, appointment reminders, and emergency alerts, with customers in transport, fintech, and emergency services.
Pricing and positioning
Billing is consumption-based — you pay for what you send, no minimums or binding contracts — and new users can register with free test credits. Against Twilio or MessageBird, seven.io's pitch is a German provider with documented reliability, 20+ years of operational track record, and straightforward pay-as-you-go pricing without enterprise sales friction.
