Re: Not getting forum e-mail notifications Thursday, 28 January 2021, 3:29 PM I'm not a big fan of Moodle notification emails. They are styled and structured in a way that makes them apt to trigger spam filters. In that respect there's not a lot you can do, other than to bolster your email reputation through other means. I would suggest using a proper transactional email platform, rather than Google's SMTP Server. Ken has mentioned Sendgrid above. I use Amazon Simple Email Service (SES). Mailchimp/Mailgun are other examples. These providers put in additional 'checks' on who is allowed to send email on their platform, and what they are allowed to send. They promptly disable the accounts of spammers. They enforce daily sending limits. They have feedback mechanisms which detect when people mark messages as spam, and will limit the sender's capabilities accordingly. Therefore, they tend to have a better reputation, especially with the 'top gun' email services such as Gmail/Google Workspace and Outlook.com/Office 365. They are significantly less likely to trigger spam filters than a run-of-the-mill SMTP server.
