Postscale

Postscale is an email infrastructure platform for developers, SaaS companies, and businesses that need reliable email delivery and processing capabilities. The platform provides transactional email APIs, inbound email processing, delivery tracking, webhooks, DMARC reporting, and privacy-focused email services. Applications can send and receive email through a simple API while integrating email events directly into existing workflows. Postscale is designed for software products that require email functionality without operating their own email infrastructure. Common use cases include account notifications, authentication emails, customer communications, inbound email processing, and deliverability monitoring. The service is operated by DNScale OÜ in Estonia and provides a European alternative to SendGrid, Mailgun, Postmark, Resend, and Amazon SES.
