Reversal Solutions, Inc review for Constant Contact: Email & SMS

I would give it 6 starts if I could. Constant Contact is the best. Easy to use. Consistently the BEST customer support of any app we have used on Shopify. Have been using it for over 10 years, except a short foray with MailChimp (ugghh- awful, no support). Beautiful easy email templates, you can automate a series of emails, great contact management,. What else can I say.
