Setup time, routing complexity, delivery failures, recovery time and administration effort.
No customer stories are published yet.
We do not invent testimonials, savings percentages, or named logos. When a design partner finishes a measured pilot and gives written permission, a story will appear here with baseline, scope, outcome, and limits. Until then, this page is the application path—not a results gallery.
Limited design partner program
Help prove MailerZ with a real workflow.
We are recruiting 5–10 domain owners and teams for guided migration and routing pilots. Participation does not create a testimonial: results are published only after measurement, review and separate written permission.
Apply for one of 10 pilot placesPILOT CAPACITY5–10qualified workflows
Applications are assessed for fit, measurable outcomes and safe migration scope.
Define scope, success criteria, evidence and rollback before changing production DNS.
Private feedback remains private. Named or anonymous results require explicit approval.
Who should apply
A real operational problem is more useful than a flattering quote.
The best partners control their domains, understand their current routes and can run external test messages. We prioritize workflows where the result can be observed without accessing unrelated mailbox content.
Moving from another forwarding provider
Consolidating role addresses across domains
Adding SMTP send-as to an existing inbox
Diagnosing unreliable forwarding outcomes
Testing alias ownership and team handoff
Evaluating catch-all risk and unknown recipients
Every approved story must answer five questions.
Baseline
What did the previous workflow cost in time, complexity or failed delivery?
Scope
Which domains, aliases and destinations were included?
Change
What configuration moved and how was rollback protected?
Outcome
What measurable result changed during the pilot?
Limits
What did MailerZ not solve, and who should choose something else?
