MailLink

The product is a unified API for Gmail, Outlook, and IMAP/SMTP that lets applications send and work with email through one set of endpoints and webhooks instead of integrating each provider separately. It is for software developers and engineering teams at startups and small to mid-size B2B software companies building email features. It is delivered as an infrastructure API and SaaS with environment-based isolation, per-environment keys, and provider configuration required only when promoting to production.
