I am a Mailchimp consultant and trainer www.mailchimptraining.co.uk and I am often asked about CRM systems that work well with Mailchimp. Capsule CRM https://capsulecrm.com integrates with Mailchimp. Capsule is based in Manchester, UK and was founded in 2009. It is an easy to use system. (I often tell clients and seminar audiences: “The CRM that is best for you is the CRM that you actually use.”)
From the start, I found Capsule to be intuitive and practical. I like the list import feature, for example, in that the software helps you to assign data to the right fields.
The Contact View feature allows you to get a 360 degree view. As marketing is “all about customers”, putting the customer in the centre of things is a good idea.
When it comes to segmenting your customers, the use of Tags is very helpful. You can create Tags that make sense to your business and then search for people that have the appropriate Tags.
Capsule integrates well with social media, which is important from a Social Selling perspective.
The free version of Capsule allows you to have up to 250 contacts. Beyond that, you are looking at a low fee per user per month. This is attractive pricing (and I have looked at dozens of CRM solutions).
