Is it possible to send the my company logo as a lettterhead to other companies who are using notes client or web mails(e.g. in yahoo mail) using stationary?
Subject: company logo using stationary
Yes - you can append HTML to the end of the email which references an existing logo on a webpage somewhere. When clients open the email, they will see you logo below.
I never recommend this when dealing with corporate america. Your best bet in reaching the corporate masses is generally plain text email, lest an aggresive mail admin send your email to a potential SPAM black hole.
This is how your emails from stores, airlines, etc have such nice “stationary” as you put it.
