We did not try to build a newsletters manager from scratch. Instead we combined the Joomla powerful content engine and the new user groups system, giving you a complete newsletters system.
If you are already familiar creating Joomla articles, then this is it!!!
How to Use
1. Create a new article to use as your newsletter, or choose an existing one.
2. Choose the user group
3. Preview in backend
4. Send a test email to you
5. Send the newsletter
* Real time preview
* independent monitoring log to avoid php timeouts.
* Define how many emails to send per second
* Test email
I send out regular emails to a variety of groups, with the information changing based on time. By setting up a cron job to automate the group the user is assigned to, and saving the email text as an article, I use SP Newsletters to semi-automate my mailouts. It saves a huge amount of time, and personalises the email...
...and the support is quick and friendly, and helpful.
