Mailjet Email by Combidesk

Absolutely horrendous app! Have never in the few campaigns we've produced had 100% of emails sent. They throttle you delivery based upon the number of, what they consider, bad email addresses. After removing these supposed bad email addresses the users called asking why their accounts were removed and the address they provided was fine. This last campaign only 7,000 of 30,000 sent and they are taking days to review why. Problem is, when we send email campaigns they are normally time sensitive. This app may be the worst we've ever used on Shopify. We highly recommend you do not use this app and find a competitor that provides a better service.
