What this means
Mailbase should not make paid plan claims yet. The public pricing message is simple: the product is free while it is in early access, and pricing may change later.
The target user is technical or semi-technical: someone with a server, a self-hosted email setup, or a useSend instance who wants a clearer workflow around that infrastructure. Exact app workflow: Mailbase interfaces with useSend via its API and webhook endpoints to manage campaigns and incoming threads.
Frequently asked
Is Mailbase free?
Yes. Mailbase is currently free while the product is in early access.
Will pricing change later?
Pricing may change later, but the current version is free to use. Any future pricing should be published clearly before paid plans are introduced.
Do I need my own server?
Mailbase is aimed at people who already have a server, VPS, hosted useSend instance, or self-hosted email setup. You need a running useSend instance, your useSend API key, a configured sending domain, and a database connection.
Do I need useSend?
Mailbase is designed primarily around useSend. Direct integrations with other SMTP servers or providers (like Resend or AWS SES) are stubbed and planned for future updates.
Can I use Mailbase without useSend?
Currently, Mailbase requires a useSend instance to handle email delivery. Support for other standalone email providers will be added in future releases.
