[keycloak-user] Sending email from Azure hosted Keycloak instances

We are planning on running Keycloak in Azure and of course need a mail server to send the emails that Keycloak generates. As you may know, Azure IP addresses are blocked from sending email to other people. I have found the following companies already: https://sendgrid.com https://www.smtp.com/ https://www.mailjet.com/ Are there any others that work better? Any experience with these or any others?
