What Happens When the Inbox Expires?
Messages are deleted. You can't read them anymore.
The address is recycled. Someone else might get it.
New mail bounces. Senders get a delivery failure.
Password resets fail. If you need to reset a password, the reset email won't arrive.
How to Make Your Temp Mail Last Longer
Don't delete the inbox. Some services keep it active as long as you keep the tab open.
Check it regularly. Some services delete inactive inboxes after a period of time.
Use services with longer lifetimes. If you need the address for more than a few hours, choose a service with longer retention.
