Sendgrid keys
There are two instances of sendgrid services
1) Paid one with dedicated ip and ip whitelists for sending mails from application. Attracs.com verified as sender. Each stable/nightly application gets it's own api key. When your app needs a key, ask Devops to create one for your app and store it in configuration.
2) Free one with only one verified sender, dev_sendgrid@aholadigital.com. If you need a dev api key, ask DevOps to create personal one for you.
