I would like to set up heroku sendgrid in Rails while referring to this site.

Go from top to bottom

I typed this command
heroku addons: create sendgrid: starter

I also typed this command
heroku config: set SENDGRID_API_KEY = xxxx_api_key_xxxx

After that, when you type heroku config, SENDGRID_API_KEY is displayed.
It seems that the following two environment variables are not set. Isn't this environment variable set automatically? Can you tell me how to set it?


heroku addons: create sendgrid: starter -app app name
If i get a message like the one shown below with the command ↑, isn't that an add-on? Also, if you try to add in from the web, you will be asked to register a credit card even though it is a free plan. I don't want to register ...

    When using an add-on, it seems necessary to register a credit card even if it is a free plan. I registered a lot.
