Limitations of Email Blocking on Mac

While learning how to block email on Mac is useful, it's important to understand its limitations. Firstly, blocking a sender does not remove their previous messages from your inbox. Also, you restrict their mail address, not the individual. This means they can still contact you using a different address.

Additionally, while most service providers on Mac allow the blocking of specific addresses, this approach often proves ineffective against spam. Spammers tend to frequently change their email addresses, reducing the effectiveness of individual address blocking. However, if a sender inundates you with emails from various addresses within the same domain, you can block the entire domain using Clean Email, as previously outlined.

In some cases, you might not even need to block emails; learning how to unsubscribe from emails can be a powerful tool against spammy newsletters and mailing lists you're no longer interested in. Read on to discover how Clean Email can assist you in this process.
