EVERYTHING MARKETING MANAGERS NEED TO KNOW ABOUT EMAIL SUBDOMAINS

Summary from the TLDR Marketing newsletter

It's important to consider using separate email subdomains within your email program to track and manage reputation without different activities affecting one another. If something happens with your root or subdomain, such as a rise in spam complaints or a big swing in send volume that lands you on a blocklist, they're less likely to affect each other if they're separate. This guide covers scenarios that benefit from an email subdomain, how many you need, and subdomain name ideas and examples.
