In the Villages, FL, I use Wix for communicating important events and reminder emails for our group of over 50 retirees for playing Kickball. We developed a single page website that new members can go to and sign up for automatic email reminders.

Using email marketing campaign that comes with Wix, I am able to pull the most recent contact list, create new email content and then send it out. Wix provides great stats such as how many were delivered, if any bounced, how many were read, etc.. At the bottom of our emails, we have an “unsubscribe” button for those that no longer want to receive emails.
Wix is free to use if you only send out a few marketing campaigns per month. After that you have to pay a subscription. In rare cases where I exceed the limit per month, I download the contact list as a CSV file to my laptop, convert to Excel format and then just use MS-WORD to send out an email using the contact list emails.
