Using Mailchimp, you can reach and grow your customer base through SMS messaging. With Email & SMS pop-up forms, embedded forms and landing pages, you can effortlessly build your SMS subscriptions and expand your contact list.

The value of an email campaign lies not just in how much revenue it generates, but also in the insights it provides about what works and what doesn’t. Constant Contact gives you numbers for opens, click-throughs, and forwards, but they offer fewer advanced reporting features than Mailchimp. Mailchimp’s in-depth reporting capabilities let you analyze audience responses and see what parts of a campaign draw the most customer interaction. You can also track your return on investment (ROI) across all channels, including your website, email list, and social media accounts when you connect your store to your Mailchimp account. This helps you learn which campaigns are working and if you should use any of your marketing funds differently.
