When downloading a new module from the app store, there is a tab that's called “Documentation”. You can usually find steps there to make the module work. Assuming you used the e-mail module with templates, the steps are as follows:
- Download the Mx Model reflection module from the App Store.
- Download and configure the Encryption module from the App Store.
- Add the snippet Administration to a custom page in a different module.
- View the example in the '_USE_ME > _Examples' folder, create a duplicate of it to your own module and make it fit your needs.
- Sub_CreateAndQueueEmail (preferred for normal environments, this will send the email in the background using a scheduled event)
- Sub_CreateAndSendEmail (preferred for sandbox environments, sends an email directly; this approach will block the users flow and doesn't include retry when sending failed).
- Post-deployment: After deploying, you have to set up your email settings and insert your own email templates using the newly created navigation items under Administrator.
- Go to the 'MxObjects_Overview' and synchronize the objects. Make sure you do this every time when you have added new objects.
