Email Fast
What it is
Email Fast combines transactional email, newsletters, campaigns and automations in a web and API platform for developers, creators and security teams. Its REST API supports scheduled sending up to 30 days ahead, batches of up to 500 messages and message timelines. Newsletter publications can include hosted subscribe pages, searchable public archives, issue pages and RSS feeds. Developers have SDKs for browser, Node.js, Python, PHP, Go and Ruby, plus a zero-dependency CLI, OpenAPI specification and compatible endpoints for SendGrid, Mailgun and Postmark. Delivered messages can produce Ed25519-signed certificates detailing the receiving server, TLS, SMTP response and timestamp. Organizations can bring their own keys and enable at-rest encryption, but encrypted sends lose click tracking, send-time optimization and per-recipient analytics. The free plan provides 2,500 emails per month; paid plans start at $9.90 a month, billed monthly. Email Fast says data is hosted in Germany and that it does not hold SOC 2 or ISO 27001 attestations or offer a HIPAA BAA today.
