Mailchimp is vital to the effectiveness of our email marketing workflow.

Mailchimp simply powers everything around sending mass emails within my organization. We use it for weekly newsletters, transactional emails, promotional emails, etc
It has proven to be easy to get accustomed to, it is effective in aspects such as marketing automation, segmentation, integration with third-party marketing applications, and customer relationship management (CRM) tools.
We have often relied on Mailchimps's vast integration with third-party software products to improve the rate of user subscription to our newsletters, synchronize email subscribers across multiple platforms and convert leads to purchasing customers.

Of course, my organization has benefitted from having access to multiple marketing features, within the Mailchimp platform. By combining the array of functionalities that Mailchimp makes available to us, we have been able to develop a dynamic marketing strategy around marketing emails, that has consistently led to increased targeted user engagement and eventually increased sales numbers.
Beyond the obvious bells and whistles, Mailchimp also provides educational resources, which we often make our new marketing employees go through, as it gives them a better grasp of vital email marketing attributes such as segmentation, tags, and generally better customer engagement practices.

Mailchimp has simply helped to continuously meet the major parts of our sales targets, as far as the email marketing aspect of our overall marketing strategy, is concerned. By using Mailchimp has enabled me to better value the enormous benefits of efficient customer segmentation.
