Hi,
As I'm not a developer or a coder, I'd like to have access to the documentation you speak of on your site (documentation included) so I can learn how to make more attractive and modern emails with pictures, logo etc..
I have no idea what to do with {{{TITLE}}} or {{{CONTENT}}} and the other possibilities offered.

Using template #62, from live site I have a warning when trying to Contact admin : <The file you tried to upload does not have a valid extension> (and was not sent)

And that one too : PHP Notice: Constant ABS_PATH already defined in /home/myloginname/public_html/oc-content/plugins/email_template/admin/template.php on line 2

If this plugin is too complicated for a novice like me or wont support pictures, logo etc.., maybe you know of another integration like Mandrill which is not free anymore. Not sure if Google mail plus is able to do the job. I know they can replace server's emails but do they take care of automatic clients emailing ? not sure.

Do not hesitate to erase this topic if you do not find it interesting for others.

Thank you. Have a nice day.

// Plugins should not learn you to develop HTML templates, you can find thousands of tutorials on google

// {{{TITLE}}} is title of email, {{{CONTENT}}} is content of email

// Not related to plugin, try to disable attachments on contact form

// Will check that, however should have no impact on plugin functionality

Differentiate between "notice" and "error".
