Using Sendgrid API to send emails

I’m sending emails using the Sendgrid API, but every email that I send does not have the Subjet.

My code looks like this:

def send_notification(sendgrid_key, p_email):
    message = Mail(
        from_email=('[e-mail]'),
        to_emails=(p_email),
        subject='subject email',
    )
    message.template_id = 'XXXXXX'

    try:
        sg = SendGridAPIClient(sendgrid_key)
        response = sg.send(message)
    except Exception as e:
        print(str(e))

Eventhought, I have set the subjet, I’m still receiving emails without subject. Moreover, I do not have any errors when my app run.

When you are using SendGrid’s dynamic templates you actually set the subject in the template, not through the API. Take a look at this screenshot to see where you set the subject in the template editor.

If you want to set the subject dynamically too, you can add a template string in the subject and set that through dynamic template variables when you send the email. Check this article on creating a dynamic email subject line with mustache templates for more information.
