Thanks for replying to my PM. We have checked your newsletter subscription and Dorico newsletter was sent two days before you subscribed to the newsletter on Jan 24.
In general, I received the confirmation that not all newsletters are sent to every subscriber to avoid spamming our customers. There is currently no option to say “bring 'em on” and for the time being, this is supposed to stay that way. Everyone should make sure that all products purchased are registered to get the newsletters for those products and don’t miss out on something.
If we want to attract existing customers to new products, we usually send newsletters to a larger amount of recipients anyway.
