Built for This Email Workflow

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

Application Email

Send system-generated messages without operating your own outbound mail servers.

SMTP & API

Connect compatible applications using standard SMTP or available REST API functionality.

Authentication

Use SPF, DKIM and DMARC as part of a properly authenticated sending setup.

Bounce Processing

Use bounce data and suppression controls to avoid repeated delivery attempts to invalid addresses.

Analytics

Monitor sending activity and available engagement information.

Scale

Move from smaller plans to high-volume or dedicated options as application usage grows.

Common Use Cases

Account Verification

Registration and email-verification workflows.

Security Messages

Password resets and account-related notifications.

Billing & Receipts

Invoices, receipts and payment-related messages.

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.

Frequently Asked Questions

Can I use SMTP-Plans for password resets?

Yes. Application-generated password resets, verification messages and notifications are common transactional email use cases.

Can I connect through API?

The current SMTP-Plans product describes REST API functionality in addition to SMTP sending.

Is inbox placement guaranteed?

No. Authentication, sender reputation, content, recipient behavior and receiving-provider decisions all influence placement.
