Saving entries with FeedMe doesn't trigger Sprout notification email
To confirm the behavior here, Sprout Notification Emails only get triggered on web requests and are suppressed for console requests and during updates and migrations. Notification Emails could get triggered in other contexts but you would need to do so programmatically.

Notification Events don't run for console requests

$request = Craft::$app-&gt;getRequest();

// Only handle notifications on web requests
if ($request-&gt;getIsConsoleRequest()) {
    return false;
}


Notification Events don't run during migrations

if ($request-&gt;getIsActionRequest()) {
    $actionSegments = $request-&gt;getActionSegments();
    if (
        ArrayHelper::firstValue($actionSegments) === 'updater' ||
        $actionSegments === ['app', 'migrate'] ||
        $actionSegments === ['pluginstore', 'install', 'migrate']
    ) {
        return false;
    }
}
