    Practical guidance for setting up Simply Send, sending email reliably, and integrating with your applications.

    How to use these guides

    Use the sidebar to browse topics. Guides cover domain setup, deliverability, compliance, SMTP relay, integrations, inbound email, workflows, rate limits, enterprise SSO, and troubleshooting. Start with the area that matches your current task, then follow related pages from there.

    Suggested path

    1. Verify your domain — authenticate sending before you go to production.
    2. Meet compliance requirements — include unsubscribe and company address content where required.
    3. Choose how you send — API, Node SDK, or SMTP relay for transactional email.
    4. Connect your tools — use the Integrations guides when wiring auth, CMS, commerce, or automation platforms.
    5. Troubleshoot when needed — check Troubleshooting and FAQ if delivery, DNS, or login issues appear.

    Finding a topic

    Open a section in the left navigation, or use docs search from the header. The guide list evolves over time, so the sidebar is always the source of truth for available topics.
