Proximus - iO

How to maximise the engagement with your newsletter

Proximus shares its latest news and offers with customers and prospects in a newsletter sent 4 times a year. The telecom giant wanted to find a solution to boost reader engagement; the open, and interaction rates for these e-mails.
To achieve these objectives, several iO specialists combined their expertise to come up with a new email template that would encourage recipients to interact with their content.


Following the adoption of this new template, we observed greater levels of reader engagement, leading to a newsletter open rate of 52%, a result never achieved before.

We also noticed a clear increase in the number of clicks on the links present in the newsletter. Overall, the conceptualization of this new template has optimised the reader experience.
