I've tried numerous times over several years to sign up to Cakewalk's newsletters. Never received a single one.
Just tried again. As usual, it thanks me and tells me I will continue to receive the emails I never receive.
This has nothing to do with spam filters - like Alex above I run my own mail server. Any spam filters are set by me, and on the domain I use for personal email and for "signing up" to the non-existent Cake newsletters, nothing gets deleted automatically.
All serial/invoice etc. emails do turn up. Newsletters - never seen a single one.
