How to Block a Sender from Mail
iOS 13 and iPadOS 13 extend the blocked contacts functionality from the Phone and Messages app to the Mail app.

To get started, open the “Mail” app and find an email from the sender that you want to block. Then, tap on their Profile Picture to reveal sender details.
Now, tap on their name in the "From" field.
Doing so will open the sender's contact card. From here, tap on “Block This Contact.”
From the next popup, confirm this action by tapping on “Block This Contact.”
The sender is now blocked. You won't receive a notification for any new email, but it will still show up in your Inbox with an icon showing it from a blocked contact (highlighted in the screenshot below).
Block Sender Options
What if you don't want an email from a blocked sender to show up in the Inbox at all? An option in the “Settings” app directly sends any new email from a blocked contact to the “Bin.”
To enable this option, open the “Settings” app and choose the “Mail” option. From here, tap on “Blocked Sender Options.”
Now, switch to “Move to Bin.”
Any new email from the blocked contact will now go directly to the “Bin.”
How to Manage and Unblock a Sender
At any time, you can go back and unblock a contact to resume receiving emails from them in your Inbox. To do this, open the “Settings” app, tap the “Mail” option, and then choose “Blocked.”
From here, find the contact or the specific email you've been blocked. Swipe left on a contact and then tap on "Unblock" to reverse the changes.
iOS 13 has another handy feature for blocking spam calls. Using the Silence Unknown Callers feature, you can automatically silence a call from anyone who's not in your contact list.
