Although email is slowly dying, it will remain a driving force of a digital strategy for a fair few years yet. Mailchimp is an email marketing system that can be extended and developed using their API. It can also be used as a CRM by integrating their tools within your website.
The system will allow you to send multi-variant campaigns and assess their performance while maintaining a list of devoted customers for your invaluable marketing campaigns.
I’ve used Mailchimp extensively at the University of Westminster for internal and external campaigns, they achieve open rates of at least 25%, which is above industry average.
