The kinds of inbox

Permanent, one-sender, prefix and temporary. What each one is for, and who it takes mail from.

Updated 17 October 20262 minTambém em português

Each kind of inbox answers a different question: who should be able to write to this address, and for how long.

Kind	Takes mail from	Ends	Counts on your plan
Permanent	anyone	never	yes
One-sender	the first sender who writes, and up to four more you let in	when you choose	no
Prefix	for each address made under it, the first sender who uses it	when you choose	yes
Temporary	anyone, until it ends	on its end date	no

Permanent

An address to publish: on a website, a business card, a profile. It takes mail from anyone and never expires. You can switch it off, and every account keeps at least one.

One-sender

For one company or person. It locks to the first sender who writes to it and bounces everyone else, so if the address leaks, it's no use to anyone. You can let up to five senders in.

Let more senders into a one-sender inbox

Prefix

A rule that makes addresses as you need them. With the prefix shop-, give a site shop-garden@yourname.clova.email without making anything first: the address is made by the first message to it, and locks to that sender. A prefix is at least 5 characters long, and makes up to 50 addresses.

Temporary

For something you'll need briefly: a receipt, a trial, a download. It takes mail until its end date, then bounces anything new. When you make it, you choose whether its mail is kept or deleted after it ends: Receipts keeps it, Throwaway deletes it.
