Rachel N. Online Marketing Manager Individual & Family Services (50 or fewer emp.)

12/27/2024 "The user interface is excellent - not just for those with technical skills but also for those who typically need a fair amount of help with technology. Very easy to navigate, very easy to set up call flows and setting. The intuitive interface is the best. The support team has been on top of it, I've actually spoken with the same person multiple times instead of being bounced to a new person with every interaction (like other experiences). I am so much more pleased with MightyCall than the last two service providers we've tried." Read full review on G2
