Whether or not the checkbox is checked is determined solely by the value of the attribute.

From the API page for ActiveField::checkbox()

This method will generate the "checked" tag attribute according to the model attribute value

Thus just add 

$model->is_email_alerts = true;

in your controller or anywhere before this call in your view.

Just to verify that this is the actual case: from the source for BaseHtml::activeCheckbox()

public static function activeCheckbox($model, $attribute, $options = [])
{
    ...
    $value = static::getAttributeValue($model, $attribute);
    ...
    $checked = "$value" === "{$options['value']}";
    ...
    return static::checkbox($name, $checked, $options);
}

And the only line in ActiveField::checkbox() where checked is set is

public static function checkbox($name, $checked = false, $options = [])
{
    $options['checked'] = (bool) $checked;
