I've been wanting to try MailChimp, the email marketing service, and finally had a chance to explore its features in recent weeks. I've been using the free version, which is ideal for small-business owners. I created some test subscribers, customized some of the signup and confirmation forms, and designed a test newsletter easily. Creating the newsletter was similar to using the drag-and-drop features of image and text blocks in Squarespace and Weebly.
Helping a client recently, I also learned you can generate a signup form in MailChimp and add its HTML code to your website to encourage visitors to sign up for your newsletter easily. You can even create email campaigns for specific groups of subscribers, based on location, gender, or other criteria that you can add, such as Interests.
I'll definitely recommend MailChimp to my small-business clients. Who wouldn't go bananas over a little primate who cheers you on at each step?
Update: As of December 2018, for a new Squarespace website, you’ll need a Business plan or higher. Connecting a newsletter is now premium feature that isn’t included on the Personal plan.
