My client application monitor physical hardware device and monitor users by mail. Therefore, emails are critical to the application.
We need to ensure that email services are constantly working as expected and that emails are delivered correctly to users.
How can I achieve that?
If you use the built-in mail support provided by Platform.sh on Grid accounts, we provide a best-effort delivery but deliver is not 100% guaranteed.
If email delivery is application-critical and/or you will be sending a large amount of email, we recommend you obtain an account with one of the many email management services on the market. They can provide you with an SLA for email delivery as well as higher limits than what we offer.
