Sciter : GUI Application with Golang using HTML/CSS

Update : 25-12-2019

This is the words from Sciter's Web site,

Sciter brings a stack of web technologies to desktop UI development. Web designers and developers can reuse their experience and expertise in creating modern looking desktop applications. Various GUI frameworks offer different UI declaration and styling languages, such as QML and XAML (Microsoft WPF). On the contrary, Sciter allows using time proven, robust, and flexible HTML and CSS for GUI definition and GPU accelerated rendering.
Before using sciter I already tried other alternatives but none of them was satisfactory as an example first i tried andlabs/ui libraryi already have written a post on it. You can read it on post gui programming with golang.  But this library is still under construction and has no support for production apps.
Secondly, I go for electron but the problem was my simple calc like the app was of size 150mb. Which is 15mb of go and other was the electron. 
Before some time I found another alternative, s…

use elasticmail api with golang example

I am not going describe anything about elasticmail itself. You can look at the elasticmails site for details about it.

I am writing this post to show you how to use it with your GoLang application.

First Create a template in the elastic mail panel. I Don't know why but when I tried to send an email as complete HTML string. It was returning the 404 error.

But when using small pieces of HTML tags like just passing

<h2> Hello </h2>
it was working.

So instead of struggling with it, I found another way,
  • Create Custome template on the elasticmails site panel
  • Use the template for mail with passing necessary details[fields] during the API call

Create A Template with placeholders

Elastic Mail Template Designer
Elastic Mail Template Designer

Highlighted elements from the left side
  • Templets menu
  • Templet Name / Id
  • Example Placeholders

GoLang Code 

function to send the email through ElasticMail with the template shown in the image with the firstname and lastname

func ElasticMailSend(){

mailClient := http.Client{
 Timeout: time.Minute * 1,

myurl := url.URL{}
myurl.Scheme = "https"
myurl.Host = ""
myurl.Path = "v2/email/send"

q := myurl.Query()
q.Add("apikey", Elasti-Mail-Key)
q.Add("to", To-Email-Address)
q.Add("template", "Welcome_New_User")
q.Add("subject", subject)
q.Add("bodyHtml", "html")
q.Add("charset", "UTF-8")
q.Add("from", from)
// merge_{variablename} will replace placeholders value {variablename} in the 
// template 
// for example,
// merge_firstname will replace {firstname} in the template as Manish
q.Add( "merge_firstname","Manish")
q.Add( "merge_lastname","Champaneri")

q.Add("fromName", From-Name)

myurl.RawQuery = q.Encode()
req, err := http.NewRequest("POST", myurl.String(), strings.NewReader(string("a")))

if err != nil {
resp, errDO := mailClient.Do(req)

if errDO != nil {
