Message blocking is a feature that allows you to prevent certain phone numbers or email addresses from contacting you. This can be useful for blocking unwanted spam or robocalls. However, if you need to receive messages from a blocked number or email address, you will need to deactivate message blocking.
The process for deactivating message blocking will vary depending on your device or email provider. In general, you will need to access the settings menu and find the option to disable message blocking. Once you have disabled message blocking, you will be able to receive messages from all phone numbers and email addresses.
