It works fine as I have used in other email services before without any issue.The interface of this service could be more user friendly for beginners like me who are not familiar with coding languages such as PHP/C++ etc but all good things come at some cost which has been paid already when we purchased the package so no worries there! Customer support was also great they were always helpful regardless if you had simple questions about billing or anything else relating to their product. This software seems safe from spamming attacks unlike others where your emails can get flagged because someone got spammed out via another account. Highly recommended especially since i am using SMTP only.I use this mainly just to send newsletters to my clients' mailing list instead of getting them through Google Apps Gmail accounts now. The main advantages here would definitely lie within how much time will save having everything centralized under one place rather than managing 2 separate tools. My productivity increased significantly due to less work load and hassle.
