Why is my Heroku app not sending emails in production with Sendgrid?

Question

My devise emails work fine in development.

But now that I have pushed to Heroku and am using the sendgrid add-on, they don't get sent. I don't get an error. It seems like it is sent just fine, it is just that it never actually reaches my inbox.

This is my config/environment/production.rb file:

config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = false
config.action_mailer.default :charset => "utf-8"
config.action_mailer.default_url_options = { :host => 'http://myapp.herokuapp.com' }

config.action_mailer.smtp_settings = {
  :user_name => ENV["SENDGRID_USERNAME"],
  :password => ENV["SENDGRID_PASSWORD"],
  :address => 'smtp.sendgrid.net',
  :domain => 'myapp.herokuapp.com',
  :port => 587,
  :authentication => :plain,
  :enable_starttls_auto => true
}

I checked those config vars on Heroku, and they return valid results.

Any ideas?

P.S. I don't have my domain pointing to the Heroku App yet, I just want to test it with the stock Heroku settings first.

一切看起来不错，您是否检查了sendgrid帐户是否已配置？

如果您在heroku上，请转到sendgrid面板以完成设置，只需访问应用程序配置文件，然后在资源（这是默认设置）下，您应该会看到sendgrid加载项，单击它并确保已完成所有设置。在这种情况下，它将要求您设置模板，但是您可以“跳过”此模板。

希望这可以帮助！
