Complete domain email delivery
Every MailerZ feature,
in a single row each.
Mail Box is Inbox, Sent, and New email. Mail Desk sits beside it. Then inbound MX, held mail, forwarding, send-as, SMTP, API, aliases, contacts, and leftover MX detection. Not a Gmail replacement. Not IMAP. Not SOC 2.
Mail Box
Work incoming, held, forwarded, and outgoing mail.
Mail Box is the portal surface at mail.mailerz.net. It is not IMAP, not POP, and not a Gmail replacement. Open a message, then reply, compose, block that address, or block the sender domain.
Portal, SMTP, and API share the same verified From identities.
- Incoming, held, forwarded, outgoing
- Reply, compose, block
- Contacts next to compose
Mail Desk
See what needs a decision before you open a message.
Mail Desk is the workspace health view. Held mail waiting for a human. Delivered and bounced counts. Domains still missing MX. Not-routed and deferred traffic. The store window.
When a message needs a call, you open Mail Box from here.
- Held, delivered, bounced counts
- Missing MX and deferred traffic
- Store window in one glance
Inbound MX
Receive domain mail without changing Header From.
Point MX at MailerZ. Messages arrive for aliases you actually created. The visible From stays the original sender. Only the SMTP envelope is rewritten with SRS.
Not a campaign sender. Not an open relay.
- Inbound MX for verified domains
- Original sender preserved
- Envelope SRS only
Held mail
Unknown addresses wait instead of becoming a spam cannon.
Free holds or rejects unrouted mail. Paid plans can forward those unknowns when you choose that route. Open Held, then forward, reject, or create the missing alias.
Safer catch-all is a decision, not a default flood.
- Hold or reject on Free
- Forward unknowns on paid plans
- Create the alias from the held row
Forwarded
Keep Gmail or Outlook. Keep the delivery record.
Forward to the inbox you already use. MailerZ stores the hop and the destination response for the plan store window. You can still open the same message in Mail Box.
14 days on Free, 90 days on Solo through Agency, 180 days on Unlimited.
- Forward to Gmail, Outlook, or another destination
- Delivery code stays visible
- Store window is not an archive
Send as your domain
Reply or compose from the same verified identity.
Every paid plan (Solo, Starter, Business, Agency, Unlimited) includes send-as On, SMTP On, and API Enabled, plus portal compose. Those paths share hourly and monthly outgoing limits. Free keeps send-as, SMTP, and API Off.
Unauthorized From addresses receive SMTP 550.
- Send-as On on every paid plan
- SMTP On on every paid plan
- API Enabled on every paid plan
SMTP
Connect Gmail, Outlook, a client, or a form.
Add MailerZ SMTP once on any paid plan. Reply from the inbox where mail already arrives. Recipients see your domain address, not a relay identity. Free keeps SMTP Off.
SMTP On on Solo, Starter, Business, Agency, and Unlimited. No separate SES, Mailgun, Postmark, or self-hosted SMTP server.
- SMTP On on every paid plan
- Verified From only
- Hourly and monthly caps both apply
API
Send from an approved application on the same limits.
API outgoing appears in the same Mail Box outgoing stream as portal and SMTP. It uses the same identities. API is Enabled on every paid plan. It is not a bulk-campaign API. Free keeps API Off.
API Enabled on Solo, Starter, Business, Agency, and Unlimited. Transactional or approved app mail only.
- API Enabled on every paid plan
- Same outgoing stream
- Not a campaign blaster
Aliases
hello@, support@, and personal addresses without per-user seats.
Create the addresses people actually write to. Route each one. Unknown mail is hold or reject on Free, and Forward on every paid plan.
Account-wide alias pools, not one mailbox seat per name.
- Named aliases
- Catch-all you choose
- No extra mailbox seat per address
Contacts
People you reply to sit next to compose.
Contacts live in Mail Box so a reply or a new message starts from a known address. Block a message or a sender domain from the preview.
Block this email. Block the sender domain.
- Contacts beside compose
- Reply from preview
- Block address or domain
DNS health
Catch leftover Google or host MX before it steals mail.
MailerZ flags leftover Google, Microsoft, cPanel, or old-host MX records that silently divert deliveries.
Fix the record set before you blame the sender.
- Leftover MX detection
- Verification TXT
- Sender-authentication records
Honest boundaries
Hosted webmail. Not IMAP. Not Workspace.
Mail Box is Inbox, Sent, and New email in the portal. MailerZ is not an IMAP or POP host. It is not a Gmail replacement. It is not SOC 2 certified. It is not a campaign sender.
Use it when you want domain webmail, optional forwarding, held mail, and paid send-as.
- Not IMAP or POP
- Not SOC 2
- Not bulk marketing
Receive on Free. Send when the limit is real.
Start with one domain. Open Mail Desk. Work mail in Mail Box. Upgrade any paid plan for send-as On, SMTP On, and API Enabled.
