Guides, FAQs and troubleshooting for E-NVOY.
How do I send my first email?
Grab your API key from the dashboard, then POST to the REST API or point your app at our SMTP relay. A working curl example lives on the home page.
Why are my emails landing in spam?
Almost always a DNS issue. Verify your domain has SPF, DKIM, and DMARC records configured, and warm up new sending domains gradually.
How do I rotate my API key?
Open Settings then API Keys, create a new key, roll it out, then revoke the old one. Active sends keep working on the new key immediately.
Is there really a free tier?
Yes — self-hosting E-NVOY is free forever under the open-source license. Our managed cloud also has a generous free quota.
Can I run this on my own server?
Absolutely. See Developers then Self-Hosted Setup for a Docker Compose stack you can launch in minutes.
