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.
