Maillayer

Maillayer is a self-hosted email marketing platform that lets you run complete email campaigns from your own server. Instead of paying monthly subscriptions to services like Mailchimp, you purchase Maillayer once for $99 and deploy it on your infrastructure. The platform connects to your choice of email providers—Amazon SES, SendGrid, or Mailgun—giving you control over sending costs and deliverability while avoiding vendor lock-in.

The system includes comprehensive features for managing contacts, creating email sequences, and tracking campaign performance with real-time analytics. It offers domain warmup capabilities to gradually build sender reputation, a React-based email editor for creating templates, and team management for collaborative work. The transactional API allows developers to send automated emails programmatically for applications requiring notifications, password resets, or confirmation messages.

Maillayer works best for developers and businesses that send high volumes of email and want to avoid recurring SaaS fees. It's particularly useful for companies running their own infrastructure who need full control over their data and email delivery. Real-world applications include sending marketing newsletters, managing customer onboarding sequences, handling transactional emails for web applications, and maintaining multiple brand identities with separate domains and sending configurations.
