Mandrill API Templating
You need to construct a hash for each element you're trying to replace. For instance, I have this inside of a template:
<h3 mc:edit="plan_info_name"> </h3> <span mc:edit="plan_info_description"> </span> <span mc:edit="plan_info_benefits"> </span>
And this on the mailer:
mandrill.messages.send_template(template,[ { :name => 'plan_info_name', :content => extra[:membership_info].name }, { :name => 'plan_info_description', :content => extra[:membership_info].long_description }, { :name => 'plan_info_benefits', :content => benefits_list } ....
