Imessages

Hi Zanaxxx,

Thanks for following up. For clarification on how blocking works, you'll want to reference this portion of the resource Block phone numbers, contacts, and emails on your iPhone or iPad:

"When you block a phone number or contact, they can still leave a voicemail, but you won't get a notification. Messages that are sent or received won't be delivered. Also, the contact won't get a notification that the call or message was blocked. When you block an email address from Mail, it goes to the trash folder. Email blocking works across all your Apple devices."

Take care.

Hi Zanaxxx,

We'll be glad to help out. There isn't a way to know if you have been blocked by another person. Everything may look as normal on your end, including a potential "delivered" message. For more information on blocking contacts, we'd recommend reviewing Block phone numbers, contacts, and emails on your iPhone or iPad - Apple Support

Cheers.
