With Microsoft and Google terminating support for Basic Authentication, Qlik suggests using a dedicated tool (such as Sendgrid, Mailchimp, or Mailgun) for bulk emails. While Qlik does not specifically endorse any of these services over the others, here's an example of how to set up Qlik Cloud Services SMTP settings with Sendgrid, taking advantage of their free tier.

Lastly, we add the credentials in the Qlik Cloud Management Console. Go to (A) Settings, (B) Email server. Complete the configuration and (C) Test the connection.
The same settings can be applied in the Send Mail block in Qlik Application Automation, under the Connection tab:
