Isolated Providers
Each workspace connects its own providers with its own credentials, priority order, and daily and hourly limits. A provider failing for one workspace opens a circuit for that connection only.
Per-Tenant Provider Configuration
Common questions, straight answers.
Which providers can a workspace connect?
Amazon SES, Postmark, Mailgun, SendGrid, SparkPost, Brevo, Mailtrap and more — 24 adapters, plus any custom SMTP server. Every connection is private to the workspace that created it.
Where are my provider credentials stored?
In the EternalEngine secrets vault. The PostFrame database keeps only a vault path for each provider connection, never the secret itself.
If another workspace's provider fails, does it affect mine?
No. Circuit breakers are keyed per provider connection, and each workspace has its own connections, so a failing account elsewhere never opens a circuit on yours.
Can I cap how much a provider sends?
Yes. Each connection has optional daily and hourly limits; PostFrame moves to the next provider by priority once a limit is reached.
