Void Relay - Email Api

About Void Relay - Email Api

Void Relay is an email API for teams that want to send mail through their own SMTP infrastructure instead of a managed email provider. It is positioned as a developer-friendly REST API with webhooks and tracking, and it supports providers such as Gmail, SendGrid, Mailgun, AWS SES, or any SMTP server. The product emphasizes no vendor lock-in, so you keep control of the email provider you use while still getting API-based email sending and delivery visibility.

The main workflow is straightforward: connect your SMTP server, send email requests through the REST API, and use webhooks and analytics to monitor what happens next. The service supports real-time notifications for sent, delivered, bounced, failed, and other email events. It also provides logs and analytics to help debug delivery problems and track email performance. Documentation and code examples are available, and the API is designed to work with any language or framework through HTTP, with a TypeScript/JavaScript SDK available and Python, Go, Ruby, and PHP listed as coming soon.

The platform also highlights global edge processing, saying requests are executed close to your SMTP server or request location to reduce latency. Pricing is presented as simple and transparent, with a free plan and a coming-soon Pro plan. The free plan includes email limits per API key, unlimited SMTP servers, REST API access, customizable webhooks, tracking and analytics, and a global edge network.
