Configure your temporary mailbox
This form mirrors the essential connection settings in the MailBridgeAPI dashboard.
Your temporary keys are generated only after this configuration is securely registered.
A temporary configuration, protected like the dashboard flow.
Your SMTP and IMAP settings are sent over HTTPS and stored temporarily so the production API endpoints can use your mailbox. Access expires after one hour; the stored mailbox passwords are then erased and the demo API key is deactivated. We record technical metadata and a pseudonymized network identifier for quota enforcement, support and abuse prevention. Demo data is not used for advertising or unrelated marketing.
Each temporary environment allows 5 outgoing email requests and 5 IMAP requests. Creation is limited per network identifier. Only public mail server hosts and standard secure ports are accepted.Read the privacy policyKeep your integration after the demo.
Create your MailBridgeAPI account to manage the mailbox in the dashboard, obtain permanent API keys, monitor errors and continue using the same endpoints in your projects.
