The ease of use, how easy it was to set up our account with amisse as well their customer service! I have used other similar products but none compare in terms usability or efficiency when compared against this product specifically designed by AMISE themselves (it's not just another generic platform like most providers). We are able improve internal communications within my organisation which has been key since we started using them about 6 months ago now - they've helped us streamline processes around emailing information internally across different departments/functions etc so that everyone can see what needs doing next without needing any additional training from myself at all.
