Segmenting your email lists by engagement can give you good results. The most important metrics to pay attention to is the click through rate and open rate. Email marketing platforms such as MailChimp and HubSpot provide ways to measure engagement.
There are many ways to segment your email lists geographically. Some examples are:
Sending out time based emails. Send out your emails to target customers by sending emails at optimum times for those in different time zones.
Send regional emails by promoting events in specific store locations.
Adjust webinars or ask me anything (AMA) times based on audience location.
Customized travel directions to a store or event based on the reader’s geolocation.
Send out offers specific to the store where a customer shops.
Draw attention and offer a personalized experience by using a specific location in your headlines.
