How to Stop Spam for Good Using Email Aliases

Spam is easier to control when each service has its own alias instead of all of them sharing your real inbox address.

The one-alias-per-service rule

The best system is simple: use a separate alias for each service, store, app, or signup.

That way, when one alias starts receiving junk, you know exactly which relationship leaked or overused it.

What to do when spam starts

If a specific alias becomes noisy, you have two options:

• Pause it if you might still need that address later
• Delete it if you never want mail through it again

This is much more effective than trying to manage spam sender by sender inside your inbox.

Replying safely

If you need to reply without exposing your real inbox, that is available on Pro and Business through MyShield's reply-from-alias flow.

On the Free plan, replying from your normal mail client will reveal your real email address.

A Practical Setup

Step 1 - Use a separate alias for every important signup.

Step 2 - Add labels if you are on a paid plan. Labels help you remember what each alias is for.

Step 3 - Pause or delete based on whether you still need the address.

Step 4 - Use a custom domain on Pro or Business if you want branded addresses for professional use.

The Long-Term Payoff

Aliases do not stop all spam everywhere overnight. What they do is stop new services from getting your real address and give you a kill switch per sender relationship.

That is the part most people never had before.
