For Agencies & ESPs
Your Email Template Department. Without the Overhead.
We help agencies and ESPs deliver high-quality HTML emails to their clients and users without hiring, training, or stressing over deliverabiliy or broken templates.
Why Master Email Templates
Designed for Agencies and ESPs That Prioritize Quality
Great email templates are hard to build. They demand specialized knowledge and extensive testing. We take care of the execution, so you can confidently deliver for your clients.
Solid
Custom HTML and ESP-native builds, accessibility- and dark-mode ready, tested across inboxes and devices.
Fast
Quick, reliable turnaround when email work piles up—no freelancers, no added headcount.
Scalable
Handle spikes, launches, and busy seasons without scrambling for help.
NDA
We work behind the scenes, follow your processes, and let you stay in control of all client communication.
Working Together
Partnership Models
Structured partnership options designed to deliver consistent quality, reliable execution, and long-term collaboration.
Team Extension
We operate fully behind the scenes as your production partner. Everything is white-labeled, scoped clearly, and designed to protect your margins—whether you’re working project-based or on retainer.
Referral
When production isn’t your core focus, send clients our way and stay involved as much—or as little—as you want. We handle delivery while you earn a referral fee or revenue share.
Ecosystem Partner
We partner with ESPs to create high-quality, production-ready templates and onboarding assets that help customers launch faster and succeed sooner.
