MailerZ handles email for verified custom domains, forwarding incoming messages to existing inboxes and sending through authenticated SMTP. Setup involves proving domain ownership, pointing MX records to MailerZ, adding aliases and destinations, and connecting SMTP. Forwarded messages retain the visible original sender name and address while the envelope is rewritten. Its hosted Mail Box has Inbox, Sent, and New email, as well as held and forwarded streams. Delivery records show whether mail was forwarded, held, bounced, or rejected, with codes and explanations. The service works with Gmail, Outlook, Apple Mail, Thunderbird, websites, and applications that support SMTP. Message recovery lasts 14 days on Free, 90 days on paid plans except Unlimited, and 180 days on Unlimited. The Free plan includes one domain and three aliases, but sending, SMTP, and API are disabled; unrouted mail is held or rejected. MailerZ is not an IMAP or POP mailbox host, permanent archive, campaign sender, or Gmail replacement. Paid plans start at $3.33/mo (annual).

Who it is for

MailerZ suits personal-domain owners, founders, small businesses, support teams, agencies, and multi-domain teams that need forwarding or authenticated SMTP sending. It is not intended as a full mailbox host, archive, campaign sender, or Gmail replacement.

What is good

  • Forwards mail from verified custom domains.
  • Keeps the original sender visible on forwarded messages.
  • Delivery logs include outcomes, codes, and explanations.
  • Works with common mail clients and SMTP-enabled apps.

What to know first

  • Free plan disables sending, SMTP, and API.
  • Free message storage lasts 14 days.
  • Not an IMAP or POP mailbox host.
  • Not SOC 2, ISO 27001, or HIPAA certified.

Verdict

MailerZ focuses on custom-domain routing, forwarding, delivery visibility, and authenticated SMTP rather than hosting a conventional mailbox. Check the Free plan limits and retention period before relying on it for sending or recovery.
