I organize email before it reaches my inbox, starting with the address I give out. I use SimpleLogin to forward mail from different addresses to the right inbox, then labels to sort it there.

An alias is an email address that forwards to an existing mailbox. It does not give me another inbox to check. You can reply to a forwarded message from your usual inbox; SimpleLogin sends the reply using your alias.

Different domains, different destinations

The domain—the part after @—decides where my mail goes:

The shared domain is useful when we both need the same message. SimpleLogin supports multiple destination mailboxes per alias, so neither of us has to remember to forward it.

One address per service

I use a service’s name in its address: service@example.com is the pattern, with my own domain in place of example.com. That lets me recognize which address received a message and control it separately.

I do not create every alias by hand. With catch-all enabled on a domain, I can make up an address at signup. SimpleLogin creates the alias when the first email arrives.

To reproduce this, you need a domain you control and SimpleLogin Premium for custom domains, catch-all, and multiple mailboxes. Connect the domain, confirm and select its destination mailboxes, and enable Catch All. Changing an existing domain’s mail routing affects its other addresses too, so account for those before switching.

Check that a test message reaches the intended inbox—or both inboxes for a shared address—before relying on it.

Catch-all also accepts mail sent to new addresses I never chose. It saves setup work; it does not prevent someone from inventing another address at my domain.

Newsletters go to Later

For newsletters, I use addresses such as newsletter.example@antoinemenard.com. Each uses the newsletter. prefix followed by the service’s name.

My Gmail filter uses to: newsletter* and applies a Later label. Choosing the address at signup gives those messages a category before they arrive.

A Gmail label is a tag, not a folder: one message can have several. Applying Later does not by itself remove mail from the inbox. Archiving removes it from the inbox without deleting it.

To create the filter, run that search in Gmail and check that it matches the intended messages. Open Show search options → Create filter, choose Apply the label, select or create Later, and save the filter. For a narrower first test, use one newsletter’s full alias in the To field. Leave automatic archiving off until you trust the matches.

Keep optional reading separate from payment failures, account warnings, and messages that need a reply. Labeling those messages does not mean they are dealt with.

Switching off a noisy alias

When unexpected spam arrives at an address I gave to only one service, it can suggest that the service shared or leaked it, or was even hacked.

When an alias starts attracting spam, I can disable it in SimpleLogin. That stops mail through that address without changing my main inbox or the aliases I use elsewhere.

Disabling blocks legitimate mail too, including receipts and password resets. If you still need an account, change its email address and check delivery before switching off the old alias. You can re-enable an alias, but messages discarded while it was disabled are not recovered.

Letting AI agents use the same system

As I started setting up AI agents to help manage my email, I needed a way for them to use this alias system. I built simplelogin-mcp, a server that uses the Model Context Protocol to connect AI assistants to SimpleLogin.

A compatible agent can create an alias, look up an existing one to reuse, or change where it forwards mail. That helps organize incoming mail at the address level; it does not read message bodies or apply Gmail labels. The API key gives full access to your SimpleLogin account; keep it private and review changes before letting an agent apply them.

Start with one newsletter alias and one filter. Once that works, use the same pattern for other services.
