What TemporaryEmail.dev is
TemporaryEmail.dev provides disposable inbox infrastructure for onboarding tests, quality assurance, and automations through a dashboard and REST API. The site says inboxes can be provisioned in three seconds. Incoming messages are parsed into text, HTML, headers, and attachment data, then sent as JSON to webhooks. Webhooks support signing and replay; paid plans add automatic retries with backoff. Documentation describes a .NET typed client through the TemporaryEmail.Contracts NuGet package and use with Refit. The free plan includes three inboxes, 200 emails monthly, one custom domain, 24-hour retention, basic webhooks without retries, and three days of logs. Paid plans are Starter at €9 a month, Pro at €29 a month, and Scale at €99 a month. Mailbox and email quotas apply, with overage from €0.30 per 1,000 emails.
