The Email Markup Database

The Email Markup Database is a comprehensive, continuously updated repository of how real-world emails are built. By scanning over a million emails, with new emails added daily, it surfaces the patterns, features, and coding techniques that real senders rely on.

This insight is valuable across the ecosystem. Email clients, email build tools and email send platforms can learn what senders really use today and make well-informed decisions to improve their products for the benefits of the email recipients and the users of their products.

Data

The data collection started in 2022. To ensure we have a fuller picture of the real state of HTML emails, we have put an effort to diversify the data and include emails from a diverse set of senders from various industries and in various languages. This is the same database we use to report on the state of accessibility in email every year.

Inspiration

This project is inspired by the Email Platform Status (no longer maintained) and the usage metrics on the Chrome Platform Status.

Explore the database

The database contains 1,433,250 emails (as of 1 December 2025 ).
