DevPy mailserver using mailgun and a post api. This is a hack to use mailgun newsletters (made for ghost, but will work wherever with a ajax request). See the example code (for ghost) here: https://gist.github.com/rawsh/554d3aa0d8519816c891ac4021ffc11f
Alternatively just make an ajax request with js.
<script type="text/rocketscript">
function doSub(elem,res) {
var em = document.getElementById(elem).value;
//get the email
fetch('http://grunt.devpy.me/subscribe', {method: 'POST',body: JSON.stringify({email: em}), headers: {"Content-Type": "application/json"}}).then(function(response) {
return response.json();
}).then(function(data) {
if(data.success) {
document.getElementById(res).innerHTML = "You are now subscribed.";
} else {
document.getElementById(res).innerHTML = data.error;
}
}).catch(function(ex) {
document.getElementById(res).innerHTML = ex;
});
}
</script>elem and res are the string id's of the email textinput and div for output respectfully.
