For agencies
Your clients want better email. You want better margins .
White-label Postern. Your brand. Your pricing. We hold the infrastructure; you hold the relationship. Stop reselling someone else’s logo and start owning the experience.
White-label is on the Phase 3 roadmap; we are talking with launch partners now. Reply to hello@postern.io if interested.
The math
- Charge clients$499 / mo each
- You pay Postern$349 / mo (Growth)
- Margin per client $150 / mo
- Ten clients in year one $1,500 / mo recurring
Numbers are illustrative. White-label tier kicks off at $800 / mo committed. Full economics on the consultation call.
Why white-label
Stop commoditising email. Own the experience.
Most agencies resell Mailchimp or Stripo. Tight margins, generic tooling, and the client could buy direct. The relationship is transactional because the product is generic.
White-label Postern flips that. The editor your clients log into is yours. The email they get back is yours. The bill is from you. The success is yours.
Higher retention because clients can’t just port to a competitor. Defensible pricing because the experience isn’t commodity. Stickier relationships because the stakes go up on both sides.
What you get
Three things that compound.
Recurring revenue, not one-off projects.
Charge $499 / mo per client for your branded editor. You pay us $349 / mo (Growth tier). $150 / client × 10 clients = $1,500 / mo, every month, no new sales calls.
Entirely your brand.
Custom domain, palette, logo, typography — your agency’s UI. Clients never see Postern. We stay invisible by design, not by accident.
You own the relationship.
You set pricing. You handle billing. You are the support contact. We support you behind the scenes; you stay the trusted name on the email.
How it works
We handle infrastructure. You handle clients.
Setup — one to two weeks.
Domain, custom CSS, API credentials, client org structure. Your white-label instance ready by week two. Kickoff call scheduled before contract signs.
Your clients never see us.
No Postern branding in the UI unless you flip it on. No "powered by" footer. Email exports work with any ESP. Invoicing goes to you — bill clients on your terms.
We are the boring part.
99.9% SLA. Zero-downtime updates. Security patches handled. Scaling without limits. You support your clients; we support you.
Where this fits
Three agency shapes that work well.
Multi-brand agencies
Five clients, five brand kits, one editor. Each client gets their templates, their colours, their merge tags — switching contexts is one click for your team.
Retainer-friendly
Recurring monthly fee fits the retainer model better than one-off campaign builds. Predictable revenue for you, predictable email production for them.
Vertical SaaS
Niche industry tooling that ships email as a feature: salons, fitness studios, restaurants. White-label Postern means you skip the editor build entirely.
