Don’t want to receive his/her/its messages anymore?
Block it, just as you do within Whatsapp.
With SpamStop you will receive messages only from the senders you have authorized:
All the regular messages will arrive as usual into your mailbox.
All the spam messages will go to a different mailbox,
accessible within your system or via webmail:
An “old-style” antispam system will be working to help you filtering the spam messages.
No messages will be lost.
You could read this mailbox once a day.
