Frequently asked questions
Is SendMailOS for marketers or developers?
Both. Create campaigns and workflows in the dashboard, or connect your application through the API and SMTP. Your team can work in the same organization while using the tools that fit their role.
Can I use my own sending domain?
Yes. Add your domain and publish the DNS records shown in the dashboard. Domain verification connects your sending identity with the platform.
Does Template Studio replace the visual editor?
The two work together. The MCP assistant creates and updates structured templates; the editor lets you keep refining their individual elements afterward.
