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.

✓

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.
