Mailstroom is a newsletter and press-release distribution platform from Dutch company Mail-Deliver, founded in 2018 and based in Bergschenhoek, Netherlands. It is built specifically for municipalities, businesses, and non-profit organizations that need to send officially branded, accessible email communications. The platform lets teams create fully branded newsletters (custom domain, logo, colors, fonts), manage a media library, pull items automatically via RSS feeds, and distribute press releases to journalist and media contact lists. Its standout focus is accessibility and compliance: newsletters are built to WCAG AAA standards with high-contrast mode, large-text options, dyslexia-friendly (OpenDyslexic) fonts, AI-generated alt text, and text-to-speech support, while data is hosted in the Netherlands with double opt-in and full audit trails to meet GDPR (AVG) requirements. Real-time open/click analytics, interest-based subscriber segmentation, role-based team permissions, and security options such as passkeys, Microsoft SSO, and two-factor authentication round out the platform. Mailstroom reports serving municipalities including Rotterdam, Enschede, and Losser, plus dozens of other organizations, and has delivered over 10 million newsletters.
