Hi, Thunderbird desktop versions work great on Mac desktop computers but the mobile version for iOS (iPhone, iPad) is still in gestation and not yet available. You can download either the actual release version 147.0.1 from here https://archive.mozilla.org/pub/thunderbird/releases/147.0.2/mac/ or the "extended support release" version 140.7.2esr from here https://archive.mozilla.org/pub/thunderbird/releases/140.7.2esr/mac/ It might be easier for a beginner to work with the esr version. To familiarise with Thunderbird please consult the following help articles: https://support.mozilla.org/en-US/kb/getting-started-thunderbird https://support.mozilla.org/en-US/kb/display-thunderbird-menus-and-toolbar#thunderbird:win11:tb147 Thunderbird has a spam blocking feature by an adaptive filter https://support.mozilla.org/en-US/kb/thunderbird-and-junk-spam-messages
