Hi, Jakob Borg

Thanks for ypur reply to the post. The solution you have provided can not be 
implemented on my system. I have provided a small sample of my code structure. 
Please take a look

type EmailTemplate struct{
BookingDetails string
}

type EmailRequest struct{
EmailTo  string
EmailBody  string
}

// get saved html with tokens from database
notificationTemplate, errVal := merchantDb.GetNotificationTemplate()
request := EmailRequest{
"t...@example.com",
notificationTemplate.Content,
}
templateData.BookingDetails += 
"Industry"+industry.IndustryName+""

request.EmailSend(templateData)


func (request *EmailRequest) EmailSend(notificationTemplateData 
interface{}) (bool, error) {
body, errParse := ParseTemplate(request.EmailBody, 
notificationTemplateData)
//email sending code here
}

func ParseTemplate(templateHtml string, data interface{}) (string, error) {
var body string
t, err := template.New("my_template").Parse(templateHtml)
if err != nil {
return body, err
}
buf := new(bytes.Buffer)

if err = t.Execute(buf, data); err != nil {
return body, err
}
body = buf.String()
return body, nil
}

Where templateHtml is the email body with tokens and data is the interface 
holding dynamic values for these tokens.
When I use ParseTemplate function to parse tokens as string values then it 
works fine.
But if I have to parse html in one of my tokens then it parses html as string 
and in email displays html as string.

How ever If I try to make assertion on it from interface to template.HTML, it 
gives me error:
cannot convert notificationTemplateData (type interface {}) to type 
"html/template".HTML: need type assertion

Hi,

Your post is a bit confusing and I think you may be using the word "parse" in 
the opposite of it its common meaning. However, if you want to pass a HTML 
fragment through a HTML template and have it not be escaped, look at the 
template.HTML type: https://golang.org/pkg/html/template/#HTML

Hello,

I am working on a SAAS based project for which I need to send emails to 
different clients on different events.

I am using email templates which use tokens (in format {{.TOKENNAME}}) that are 
made dynamic while sending emails. Now these token are parsed by using 
"html/template" package.

following is the custom function that I have made to parse these tokens into 
email body.

func ParseTemplate(templateHtml string, data interface{}) (string, error) {
var body string
t, err := template.New("my_template").Parse(templateHtml)
if err != nil {
return body, err

Can anybody tell me what should I do to parse html in ParseTemplate function??

Thanks!
