Track specific audiences
Some newsletter readers are especially valuable. And you may want to track how those groups engage with newsletters.
GlueLetter enables you to track Audiences — specified groups of readers — to see how they engage with your newsletters.
Here are some common types of Audiences that GlueLetter could track for you:
- Existing subscribers, members or donors you want to engage and retain
- Previous customers you want repeat purchases from
- Demographic groups (age brackets, genders, etc.)
- Frequent readers
- People using certain types of email addresses (.gov, .edu, or even specific organizations like @whitehouse.gov)
These groups may have different interests and behaviors than your total newsletter audience. GlueLetter’s dashboards and custom reports can show you the specific stories, topics, campaigns and other content that is building loyalty with any specific Audience.
