Block a sender or a whole domain

Someone keeps writing to you. Stop their mail in every one of your inboxes, or a company's from every address it writes from.

Updated 17 October 20262 minTambém em português

A block turns away a sender's mail in every inbox of your account. Their mail is refused with the answer an address that doesn't exist gets, so they aren't told they were blocked.

Block a sender

  1. Open a message from them.
  2. At the bottom, select Block.
  3. Clova asks first. To keep their other mail, untick Also delete.
  4. Select Block and delete. The conversation you're on is deleted with the block.

Clova always asks before blocking.

You can also block from the list. On a computer, point at a conversation, and select the block sign at its end. On a phone, swipe the conversation to the left, or press and hold it, and select Block.

Block a whole domain

For a company that writes from a new address every time:

  1. Open one of its messages, and select Block.
  2. Tick Block the entire domain. Also delete then counts the mail from every address there.
  3. Select Block and delete.

The block covers the domain and every domain under it: blocking focusapps.example also blocks news@mail.focusapps.example. It isn't offered for Gmail, Outlook and other providers, where an address can be anyone's.

Block an address by hand

  1. At the bottom of the sidebar, select your name. On a phone, select More at the bottom of the screen.
  2. Select Blocked senders.
  3. Select Add to blocklist.
  4. In Their full email address, type the address.
  5. Select Block sender.

A whole domain can't be typed here: block it from one of its messages.

Unblock

  1. In the account menu, select Blocked senders.
  2. Next to the address, select the trash.

Blocked senders, with whole domains first.

Their mail reaches you again from then on.

Good to know

Every spelling of an address
Capitals make no difference. At Gmail, Outlook, iCloud, Proton, Fastmail and Zoho, nothing after a + does either, and at Gmail, nor do dots: blocking ana.lima@gmail.com also blocks analima+news@gmail.com.
Only mail that can be checked
A block works on mail that proves who sent it. A message in their name that can't be checked still arrives, and if you block from one, Clova says so.
Who keeps trying
On a computer, Blocked senders counts how many times each has tried to write since, and shows the last time and the IP address it came from. Unblocking someone forgets this.
Contacts
A block takes them out of your contacts. If you write to them later, Clova asks whether to unblock them first.
