Built for This Email Workflow

Use SMTP infrastructure, authentication and monitoring appropriate to your sending requirements.

REST API Access

The current SMTP-Plans product includes REST API functionality for programmatic workflows.

Transactional Workflows

Build verification, password reset, notification and billing-email processes.

SMTP Alternative

Use SMTP where it is simpler and API-based integration where your application benefits from programmatic control.

Authentication

Support authenticated sending domains with SPF, DKIM and DMARC.

Reporting

Monitor available sending, bounce and engagement data.

Scale With Usage

Increase sending capacity as your application's email requirements grow.

Common Use Cases

SaaS Applications

User lifecycle and product notifications.

E-commerce Systems

Order, account and customer messages.

Custom Platforms

Email generated by your own software and business workflows.

Deliverability matters: SMTP infrastructure can support a strong sending program, but inbox placement cannot be guaranteed. Authentication, sender reputation, recipient consent, list quality, content, engagement and receiving-provider decisions also affect delivery.
