List segmentation is the process of placing your email contacts into specific email lists based upon information you know about them including buyer persona and lifecycle stage. List segmentation is important because it helps you deliver content that is most relevant to the needs and wants of your audience.
By sending email content that is targeted and segmented to a specific audience, your emails are naturally more engaging and are therefore, opened and read more consistently. This will earn you a better sender reputation with your audience and lead to more conversions and ultimately, increased sales.
In addition to segmenting audience members by buyer persona and lifecycle stage, look at ways you can further segment your email lists to achieve more defined audience targeting. Information like geography, age, industry, past purchases and buying frequency, among other options, can help you achieve better segmented email lists.
