I've been looking at a few list management services such as Constant Contact - but they all seem to require that an unsubscribe link is present in the footer of every email you send out. This is, of course, as it should be for a regular, opt in newsletter - but I am looking for a list management service which would enable me to email a list of clients who are permanent advertisers on my website.
I need to send them regular emails regarding their advertising payments which are due etc - so I obviously don't want them clicking on an unsubscribe link - they 'unsubscribe' by contacting me to cancel their advertising.
Any suggestions on a solution to this?
