What is temporary email?
A temporary email address receives messages for a short time, typically for testing, signing up for services, or keeping your main inbox off marketing lists.
TinyMail provides receive-only temporary inboxes. The service does not send email or provide an SMTP relay. Inboxes are public to anyone who knows or guesses the address. Messages are kept for up to 3 days before being automatically deleted.
How to use TinyMail
- Open the homepage and use a random address, or enter your own
user@domain. - Send a message to that address from the system you are testing.
- Refresh the inbox to see the message list; open a message to read its sanitized HTML content.
The inbox checks for new messages every 10 seconds while this page is open; you can also refresh it manually. Delivery time depends on the sending system, and some services do not accept temporary addresses.
Use a domain you own
Choose your test domain
Use a domain you own and can manage in DNS. Keep it separate from your everyday email domain.
Configure its MX record
Point MX to
contropro.online. Follow the domain setup guide before changing existing mail routing.Verify and receive a test message
Add the domain above after DNS updates, check that it is online, then open an address on it and send a nonsensitive test message.
A custom domain does not make an inbox private or guarantee message delivery.
Practical ways to use a temporary inbox
Test your own signup flow
Check the email your application sends to a synthetic test account.
Review transactional emails
QA templates and formatting using synthetic order and account data, never real customer details.
Receive a one-off message
Use a short-lived address for information that is safe to be public and does not need long-term storage.
Share your primary address less
Keep your everyday address out of optional, nonsensitive exchanges where temporary email is accepted.
Organize a custom test domain
Use recognizable test addresses on a domain you control, separate from your production mail.
Exercise an API integration
Use the documented REST endpoints to list and read synthetic messages in your test scripts.
