I use this service for my business, it's free! It is easy to set up an account and get started using it right away. There are many options available in order to create your own templates but some of them can be confusing at first. Once you understand how things work, they become easy to use. This software has been very useful so far because we have been able to track our mailings with ease. We also like that all emails sent through GMS are GDPR compliant which makes us feel more secure about sending out customer information via email.
