Create every address you need.
Control everything else.

Choose the safe default for your domain

Address control without mailbox sprawl

Separate the public address from the destination inbox.

An alias is a durable routing rule. It lets your business change people and inboxes without changing the address customers know.

Role addresses

Create sales@, billing@, support@, careers@, or any address appropriate for your organization.

Team distribution

Route a shared public address to the people who need it without sharing a mailbox password.

Destination changes

Move delivery to a new person or inbox while the public-facing address remains the same.

Safe unknown-recipient handling

Free domains hold unknown recipients instead of silently forwarding every guessed address.

Intentional catch-all

Paid plans can forward catch-all mail when the operational benefit is worth the added spam exposure.

Fast disablement

Stop a noisy or compromised alias without disrupting every other address on the domain.

A clear product boundary

Catch-all is a trade-off, not a checkbox.

It prevents missed mail caused by typos, but also accepts messages to invented addresses. MailerZ makes the choice visible.

MailerZ is a strong fit when…Separating public roles from private inboxesAgencies managing several domain identitiesChanging team ownership without changing addressesCapturing important mistyped recipients intentionally
Choose another tool when…×Treating every alias as a separate stored mailbox×Using catch-all without monitoring spam volume×Creating deceptive or unauthorized sender identities×Avoiding consent rules for outbound email

Organize the domain, not more inboxes.

Create your first aliases free and upgrade only when you need unlimited routing or catch-all forwarding.
