The record

Purpose: TemporaryEmail.dev provides disposable inbox infrastructure for onboarding tests, QA, and automations.
Mailbox setup: Users can create inboxes through the REST API or dashboard, and the site says inboxes can be provisioned in 3 seconds.
Message handling: Inbound messages are parsed into text, HTML, headers, and attachment data, then delivered as JSON to a webhook.
Webhook delivery: The service supports signed webhooks, replay, and—on paid plans—automatic retries with backoff.
Integrations: The documentation provides a .NET typed client via the TemporaryEmail.Contracts NuGet package and describes using Refit.
Security: The maker says data is encrypted at rest and in transit, with HMAC-signed webhooks, secret rotation, tenant isolation, and rate limiting.
Data residency: EU data residency is listed as available on Pro and Scale plans.
Limits and overages: Plans enforce mailbox and email quotas, and overage starts at €0.30 per 1,000 emails.
Support: The maker offers direct support by email and says paid plans are activated manually.
Consumer inbox lifespan: The linked temporary inbox service says each inbox is valid for roughly one hour and messages retain their HTML formatting.
Privacy and retention: The privacy policy says it stores mailbox identifiers, generated addresses, and delivered messages until expiry, then permanently deletes expired messages.
Price from: €9/mo
