What TemporaryEmail.dev is
TemporaryEmail.dev provides disposable inbox infrastructure for onboarding tests, QA, and automations through a web dashboard and REST API. Users can create inboxes through either, and the site says provisioning takes three seconds. Incoming messages are parsed into text, HTML, headers, and attachment data, then delivered as JSON to a webhook. The service supports signed webhooks and replay; automatic retries with backoff are available on paid plans. Its documentation describes a .NET typed client through the TemporaryEmail.Contracts NuGet package and use with Refit. The free plan includes three inboxes, 200 emails per month, 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. The maker says data is encrypted at rest and in transit, with HMAC-signed webhooks, secret rotation, tenant isolation, and rate limiting. Custom domains are in Early Access and require guided DNS verification and MX configuration.
