Sendgrid returns 202 but doesn't send email

Question

I'm trying to get the basic "hello world" of sendgrid working, but have so far been unsuccessful. The response returns code 202, suggesting that it will send the email, but the email never sends out. Does anyone know what's going on?

import sendgrid  sg = sendgrid.SendGridAPIClient(apikey='**my-api-key**') data = {   "personalizations": [     {       "to": [         {           "email": "[email protected]"         }       ],       "subject": "Hello World from the SendGrid Python Library!"     }   ],   "from": {     "email": "[email protected]"   },   "content": [     {       "type": "text/plain",       "value": "Hello, Email!"     }   ] } response = sg.client.mail.send.post(request_body=data) print(response.status_code) 

Answer 1

I just had this issue: I created an account with SendGrid and tried to get the basic example working, the API would return a 202 response, but the email was never sent, and the SendGrid web UI's activity feed showed no activity.

I submitted a SendGrid support ticket and ~8 hours later received a response saying that they had disabled my account's ability to send emails:

Hello,

Thanks for contacting SendGrid Support!

It looks like your account has been closed by our compliance team and this is the cause of the issue.

To reactivate we’d like to know a little more about the email you’ll be sending through SendGrid. Please elaborate on the following:

1. The nature of your business, the services you provide, and your potential customer base

2. Your sending frequency and volume

3. How you collect your recipient addresses (link to opt in page, or sign up process)

4. How you will allow your recipients to opt out of your emails (whether you plan to use SendGrid’s one-click unsubscribe feature, or if you have your own method)

5. The types of messages you will be sending (transactional or marketing)

Please reply at your earliest convenience in order to continue the activation process. Thanks for your cooperation!

~15 hours after submitting my answers, I received a response saying my account had been "activated":

When I then ran the basic example code with my email address set up as the recipient, the email showed up immediately in my Gmail inbox.
