I like that this is available in so many different countries which makes it very convenient to have access from all over the world.
It's easy to set up and use as well! Sometimes there are problems with getting emails through but they usually resolve themselves if you contact them straight away. The customer service can be slow at times too but not always- just be patient! As mentioned above, sometimes you may get blocked by filters or blacklisted (but this rarely happens) - make sure your email address isn't listed somewhere else first though! We're using it for marketing purposes only currently, however we will also be able to send out bulk notifications and reminders when needed.
