Infographic: Segmented Emails Are the Future of Email Marketing

Are you still sending the same email to all your subscribers in 2025? If yes, then you might still be living in a past era when broadcast emails worked just fine. But if you want higher open rates and ROI from email marketing, then you must prioritize segmented emails. Email personalization is the present and the future of email marketing.

Email segmentation involves sorting your subscriber email list into small targeted groups using specific criteria such as demographics, recipient behavior, and purchase history. 

The goal in personalized emails is to deliver content that’s more relevant to each group. This way, you can build valuable relationships with customers and engage with them at a deeper, personal level.

Data has shown that segmented email marketing has many benefits, including higher open, click, and conversion rates, as well as higher revenues.

 

Why Email Marketing?

There are several reasons why marketers should continue using email marketing. The top three are:

• The email marketing market is recording rapid and consistent growth.

• Many customers still open emails.

• Email still delivers a significant return on investment (ROI).

 

Rapid and Consistent Email Marketing Market Growth

According to Mordor Intelligence, the email marketing market is on an upward trend, estimated at $12.88 billion in 2025 and projected to reach $22.81 billion by 2030.

Such vibrant growth presents a significant opportunity for marketers to drive customer engagement, reach a wider audience, and eventually, a higher ROI.

 

Many Customers Still Open Emails

According to HubSpot, in 2025, 42.35% of all marketing emails were opened, with some industries recording up to a 55% consistent open rate. Also, data shows a significant number of clicks in the email and an insignificant unsubscribe rate.

 

Email Still Delivers a High ROI

Marketers who use emails to reach out to customers record a high ROI ranging from $10-$50+ for every dollar spent. According to Litmus:

While these statistics apply to the overall use of emails for marketing, the benefits of using segmented emails are even better.
