With this wonderful piece of software I met my customer's need in few minutes.
They want to planify 5 mailings a week to several users list and different contents.
Acymailing (Essentials Version to get "planify option") did the job very well.
Thanks to developer team.
I use it for everything, for mysql data connections, for googlemapping, for small applications inside joomla.
Developpers Rob and Hugh are very nice people and very competent.
it is a free component but not so easy to manage so "Bronze support" is necessary to use it correctly and to be able to download some wonderful extras...and to encourage them to go farther.
