Postscale

Postscale provides an API platform for managing transactional email, inbound message processing, and user privacy through masked email addresses. It addresses the needs of developers and organizations seeking a unified solution for sending emails, handling incoming messages, and protecting user identities, all accessible via a single API.

The platform's transactional email capabilities allow users to send emails with a simple HTTP request, track delivery events such as bounces and complaints in real time, and utilize features like high deliverability, authentication, suppression handling, and delivery queue management. Postscale supports webhooks for real-time event notifications and offers template management with dynamic variables, version control, and A/B testing. Dedicated IP addresses are available on certain plans, and failed deliveries are retried automatically using exponential backoff. js, Python, Ruby, and PHP, enabling integration with different runtimes and frameworks, and facilitating webhook signature verification.

For inbound email processing, Postscale parses incoming emails and delivers them to applications as JSON via webhooks. This includes extracting headers, body content in HTML and plain text, attachment metadata, and providing download links for attachments. The platform supports routing rules based on sender, domain, subject, headers, or authentication results, with options for regex filtering and logical operations. Additional features include automatic thread detection, built-in spam filtering with configurable thresholds, and DMARC aggregate report collection and analysis.

Postscale's privacy and masked email features allow the creation of unique aliases that forward to real addresses, keeping user identities concealed. Users can control aliases individually, reply from masked addresses with outgoing emails rewritten for privacy, and use custom domains for maintaining brand consistency. Each alias can be forwarded to multiple destinations, and usage can be tracked and managed through the dashboard or API.

Designed for scalability and reliability, Postscale consolidates email infrastructure needs into one platform, offering RESTful endpoints, comprehensive documentation, and a developer-focused console.
