The support team are great, they always respond quickly when needed! Also their software works perfectly well with our system as we run it through an exchange mailbox (which has its own issues!).
No major dislikes at this stage but if you have any questions during your installation then please contact them for help because I can't answer that question myself without knowing what exactly my organisation requires from such service providers so far all seems fine though!! Have used many different email gateways over time including cloud services - none work 100% reliably or consistently like cellpoint does which makes life easier especially where compliance requirements need dealing with regularly e.g GDPR etc..
