Self-Hosted Email Marketing Platform Broadcast Powers 11 UK Brands on AWS Infrastructure
Multi-tenant platform saves £7,000+ annually with zero security vulnerabilities and 50,000 emails per day capacity
LONDON, 25 March 2026 — LONDON, 25 March 2026 — Razormind has revealed that its self-hosted email marketing platform Broadcast now powers email campaigns for 11 UK brands, operating on dedicated cloud infrastructure infrastructure with a capacity of 50,000 emails per day and saving clients more than seven thousand pounds annually compared with commercial software-as-a-service alternatives. Broadcast is a multi-tenant email marketing platform built as an alternative to MailChimp, MailerLite and similar commercial services. The platform runs on dedicated cloud Simple Email Service infrastructure, giving each tenant dedicated sending capacity without the per-subscriber pricing models that make commercial platforms increasingly expensive as mailing lists grow. A recent security audit of the Broadcast platform identified zero vulnerabilities across its authentication, data handling and email transmission systems. The platform implements row-level security at the database layer, ensuring that each tenant's subscriber data, campaign history and analytics are completely isolated from other tenants. The cost savings compared with commercial alternatives are significant. A portfolio of 11 brands sending regular newsletters through MailChimp or MailerLite would incur combined subscription costs exceeding seven thousand pounds per year. Broadcast's dedicated infrastructure costs a fraction of that figure, with per-email sending costs of approximately 10 pence per thousand emails. "Email marketing platforms have become extraordinarily expensive for what they do," said Gareth Ellis, Founder, Razormind. "When you manage multiple brands, the per-subscriber pricing model punishes growth. Broadcast gives our clients enterprise-grade email capability at infrastructure cost." The platform includes campaign creation with a visual editor, subscriber management with tagging and segmentation, automated welcome sequences, delivery analytics with open and click tracking, bounce handling and unsubscribe management. Each tenant accesses the platform through a branded subdomain with their own login credentials. Privacy is a core design principle. Unlike commercial email marketing platforms that aggregate subscriber data across their customer base for advertising and analytics products, Broadcast stores all data in a dedicated secure database PostgreSQL database under Razormind's direct control. No subscriber data is shared with third parties for any purpose. The platform's sending infrastructure uses dedicated IP addresses with proper SPF, DKIM and DMARC authentication for each tenant's sending domain, ensuring maximum deliverability and protecting sender reputation. Domain configuration follows a standardised pattern using news.domain.com subdomains for marketing sends, keeping marketing email reputation separate from transactional communications. Broadcast is available to Razormind clients and portfolio brands. The platform is available to Razormind clients.
