Hello @MARYB014 ,
You have access to all templates within your account during a trial (both standard and plus campaigns). If you are looking at the templates and do not like the ones listed, if you scroll to the bottom of the page you will see a button to "View All Templates" this will show you all available templates for the campaign type that you have selected.
I apologize for the confusion. We have begun updating all account to the new Constant Contact Experience. In the new experience all templates are now mobile responsive and have all been updated. To get a full tour of the new experience please take a look at the FAQ below.
Hello @GregL133, we really have made a push with our templates to move towards having mobile responsive templates. In our push to go mobile please look for the mobile icon showing it is mobile responsive. You will find when scrolling to the bottom of the page there will be a link to view all templates and hopefully that will help you to find the perfect template.
