[SalesForce] Preview email content of email templates before sending

I am developing a feature to send a email from a Custom Visualforce page.
For this I am using the Messaging.SingleEmailMessage class.

I need to give users, the option to select email templates from a set of email templates in the Salesforce 'Email template'.

However i cannot find a way to preview emails which will be sent. My email templates will have data mapped from the respective record. How can i solve this problem of previewing the email templates with the values from email templates?

Please suggest.

In short, there is no simple 'preview' function available to you. You could work around it using Visualforce pages/components for the preview. Assuming you are using Visualforce Email Templates, you could do something like this:

Copy the relevant content out of the Visualforce Email Template into a Visualforce Component
In your Email Template, reference the component e.g. <c:EmailContent obj="{!relatedTo}"/> to render the content
Create a new Visualforce page, also referencing the component (as #2)
Use the Visualforce page just created as a preview

If you wanted to show your user a list of Email templates to choose from, you could simply query the EmailTemplate object with some valid criteria, e.g.

Select Name from EmailTemplate Where IsActive = true

[SalesForce] Visualforce HTML Email Template – Ability to Edit Text in Preview Before Sending

This attribute contentEditable="true" is only an HTML attribute, so it enables you to edit the content of what is on an HTML page, but SalesForce doesn't know about your edits or send your changes out with the email.

Editable emails would really be nice, but VF e-mail templates don't seem to have that feature.

After doing some research I able to figured out how to achieve this, if someone has better way of doing please post it here.

1) I modified my VF email template and added attribute language="{!recipient.LanguageLocaleKey}"

2) After doing that, I created Custom Labels as shown below:

3) After creating the Custom Labels I just had to plug them in the VF email template as shown below.

<messaging:emailTemplate recipientType="User" language="{!recipient.LanguageLocaleKey}"
    relatedToType="custom_object"
    subject="Case report for Account: {!relatedTo.name}">

<messaging:htmlEmailBody>
    <html>
        <body>

        <p>{!$Label.Translation_Custom_Label_Line_1} {!recipient.name},</p>
        <p>{!$Label.Translation_Custom_Label_Line_2} {!relatedTo.name}.</p>
        <table border="0" >
            <tr>
                <th>{!$Label.Translation_Custom_Label_Line_3}</th> 
                <th>{!$Label.Translation_Custom_Label_Line_4}</th> 
            </tr>

        </table>
        <p/> 
        </body>
    </html>
</messaging:htmlEmailBody>

4) If you want to test it out, go back to the User account change the Language and Save the record, then go back to the Email Template and do a Send Test Email

It works fine without any issue, again if you have a better solution please let me know and hope this will help others.
