The best part about this software are their customer support team who always helps me in any problem that I face during my work day. Sometimes they don't respond quickly but it's never due to them not being helpful at all! They're very professional and knowledgeable when we talk technical stuffs - so far everything has been great working through carahsft! Nothing really specific here as there are no issues yet! Just be careful if you have bad experiences from other softwares or providers out there because sometimes others might try scamming your money by promising free services which end up costing more than expected afterwards. My job entails managing email addresses for our organization.
