In modern email marketing, time is money. Every minute spent manually building an email drains team resources, slows down testing hypotheses, and reduces the pace of business growth.Letteros changes this reality with a unique philosophy: ready-made master templates and a module system let you build emails 5 times faster and cheaper than the classic process — without designers or coders.

We'll explain how it works and why Letteros has become the go-to tool for anyone who values efficiency.

What is a master template and what are modules?

In Letteros, a master template is a library of 100–200 ready-made modules used to build any kind of email:

  • automated triggers,
  • mass campaigns,
  • special campaigns,
  • welcome and reactivation sequences.

Modules are building blocks:– headers,– banners,– content blocks,– product blocks,– footers, and dozens of other elements.

We adapt these elements to your brand: creating an icon set, brand colors, fonts, illustrations. The result — your unique style, without extra custom development.

How does this speed things up?

In practice:✅ email prep time drops from 1–2 hours to 10–20 minutes — at least 5x faster,✅ savings on agencies, designers, and coders,✅ fewer mistakes, because everything's already been tested,✅ a consistent design standard → emails always look flawless, no matter who builds them.

The main advantage: Letteros fully replaces an in-house or outsourced coder — you no longer spend time and money coding emails by hand.

And that's just the start:Letteros also has other built-in tools that speed things up even more:

  • automatic image compression (PNG, JPEG),
  • a UTM tag generator,
  • performance analytics,
  • email testing before sending,
  • a built-in GIF editor,
  • integrations with CRM, CDP, and ESP.

Why this matters for business

  • For marketers: more time for strategy, less for routine tasks, and you can work without a coder.
  • For business owners: fast launches of new campaigns and promotions → revenue growth.
  • For CRM specialists: a consistent standard, fewer errors, easy data integration.

Letteros is like an email marketing agency, just 5 times cheaper and 5 times faster. And without coders.

How we work with clients
