Six plans with clear operating limits

Pay for the capacity
you actually use.

Every plan includes domain email forwarding and delivery visibility. Free keeps send-as, SMTP, and API off. Upgrade for more domains, aliases, seats, storage, outbound capacity, and unknown-recipient forwarding.

Outgoing emails/month

The maximum number of messages sent through MailerZ SMTP during a billing month. Free has SMTP off, so this row is disabled.

Outgoing emails/hour

The hourly sending-rate ceiling for approved domain identities. It does not increase the monthly allowance.

Unrouted mail: hold or reject

Mail to an unconfigured recipient is retained for review or rejected. Free cannot forward unknowns.

Unrouted mail: forward

Eligible paid plans can route unknown recipients using the configured catch-all destination.

What does each MailerZ plan include?

Free is one domain, three aliases, one seat, a 14-day store, send-as disabled, SMTP and API disabled, and unrouted mail held or rejected only. Solo is $40 per year: 3 domains, 15 aliases, 1,000 outgoing/month. Starter is $8 monthly or $80 yearly. Business is $19 or $190. Agency is $39 or $390. Unlimited is $99 monthly or $990 yearly, with a 180-day store and 100,000 outgoing/month. Confirm these numbers on this page before quoting them; they are not an SLA.

Start with Free. Move up when a limit becomes real.

Test one domain and the inbound forwarding path before choosing paid SMTP capacity.
