The best part is that it's free to use. I have used this for sending bulk emails to customers. It's very easy to use. There are some minor issues but nothing major. If you're looking for an email service provider then definitely give it a try. You can send mass emails to your clients without any problems. It's also very reliable. Using this service, I don't need to worry about my emails going missing or not being delivered. It is easy to use for our customers as well with it being hosted locally in Canada! I wish there was more support available when using their service but they do have great customer care if you need assistance at any time during your contract period. We are able to provide e-commerce delivery solutions through this platform without having additional infrastructure costs or maintenance issues that would otherwise be required from an external mail server provider such as Google Apps etc..
