Interspire Email Marketing Software is excellent tool to send email campaigns and tracking the Newsletters clicks and views, kinda one in all, create, send and track.
While setting up Interspire Email Marketer recently for a client, and although Installation went smoothly and click tracking worked perfectly. The only issue I had was with “unsubscribe” link placement. I had to test several options before finally sorting it out, just place the following code at the end of your template and that should work.
hope that helps.
