Hi George, thanks for the reply! My project is a spring MVC project. I'm using a trial version of Sendgrid. I haven't updated my billing details(could this be a reason for failure). Here's the relevant code snippet :
Method 1: public static boolean sendEmail(String emailId) { Sendgrid mail = new Sendgrid("my_username","my_password"); //Input: SendGrid username, password mail.setTo(emailId) //to ID .setFrom("my_email...@gmail.com") //from ID .setSubject("Sending first mail with Sendgrid") //subject .setText("thanks for subscribing!"); //content try { mail.send(); } catch (JSONException e) { logger.info("JSON exception occured"); return false; } return true; } Method 2: I've tried the version that uses Api key too: Email from = new Email("my_emai...@gmail.com"); String subject = "Sending first mail with Sendgrid"; Email to = new Email(emailId); Content content = new Content("text/plain", "thanks for subscribing!"); Mail mail = new Mail(from, subject, to, content); SendGrid sg = new SendGrid(SENDGRID_API_KEY); Request request = new Request(); request.setMethod(Method.POST); request.setEndpoint("mail/send"); request.setBody(mail.build()); Response response = sg.api(request); if(response.getStatusCode()!=200) { logger.info("response status is ", response.getStatusCode()); return false; } -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
