My first impression of saseul was that it is extremely well organized with an interface which gives access to all essential features in one place! You don't go around different screens for creating tasks, time entries or invoicing - everything can be managed from within just 1 page!! There are some small things I dislike such as having two dashboards/interface where you have more than what they say (as we should expect) but overall very good experience so far! The only thing preventing me right now would probably come by my own expectations towards this platform because maybe i'm expecting too much given our target customer profile at present :) Definitely consider using their services if your business deals mainly wthin continental countries and Europe since shipping & custom clearance procedures might become problematic without them ;-) The ease of use, the customization options, the support team is awesome, the price is great. I can't think of anything that I don't like about this product. It's all you need for your email marketing needs. There are so many features to learn but it's worth it.
We have used MailChimp before and we were never happy with the results. With SASEUL we get amazing results. Our open rates are very high and our click throughs are great too.
