Спасибо за все ваши предложения - БОЛЬШАЯ ПОМОЩЬ! Вот чем я закончил, если вам интересно. Предварительный просмотр некорректен в браузерах, но корректно отображается в почтовых клиентах на стороне получателя. Я успешно протестировал Gmail, Outlook 2000/2007, Yahoo (старый / новый), Hotmail, Thunderbird.
Также нашёл это руководство по CSS в письмах http://www.campaignmonitor.com/css/
(в основном избегайте этого при отправке клиентам Outlook 2007/2010 и Gmail)
