Great assistance and clarification of my misunderstanding.
By Guy P.
Campaign Monitor is the worst. Look out for the no exit claus in their contract. Unfortunately due to COVID-19 our business has been severely impacted like a lot most of our profit and budgets we have had to write down more then 50%. They aren't willing to help or assist us as a business. Not even an early exit fee, just deferred payments. The platform is not even that good, everyone - look at Klavyio

Premier customer for some time but then treated by CM's "customer support" robots like garbage.
By Richard A.
One of the most counter-intuitive and bug-ridden email service providers out there. There are many other businesses that do it better and email isn't even the mainstay of their business. Limited functionality, poor image compression and incredibly weak customer support.
By Daniel B.
Like dealing with a robot with no desire to help paying customers. Parts of their interface have always bothered me but I carried on. However, the customer service is so bad it's laughable and they seem completely unbothered that we are leaving after 5+ years of business due to their inflexibility.
By Owen K.
Spent the last 2hours designing an email using their 'free design feature'. After I had added all the content, I requested to be moved to 'preview' I was taken to the original format, not the design I had painstakingly created. I then was asked to fill out my contact details only for the screen to freeze and not be able to move to the next section. Will not be using again, as clearly not fit for purpose and looking at the other reviews, I perhaps should have done some due diligence before wasting half my money! Thanks Campaign Monitor!
