Of course - Cymatics entire business model is harassing the hell out of people via email to either look at their new sample packs or buy them on discount.
If you pay attention, they give away free packs + will have promos where they give you credits for free packs and then put a bunch of packs up for discount. I'm not particularly fond of their samples, but free is free and I've found stuff I like in their collection.
Free is never free. They’re getting some value from you whether it be information or actual money.
Right, for example, your email address so they can harass the hell out of you (if you stumble onto the site and see the "FREE SAMPLE PACKS" link). Or the free packs are just partial and they're supposed to entice you to buy the whole pack (where the actual good samples are). Or the packs lead you to their not-free VSTs (which I'm also not terribly interested in, but I'm not their target for that stuff).
Does it need to be a valid email?
Technically fuckyou@example.com works. better yet use their own support email address.
That last one is heavenly lol
Most of the music production companies are terrible to customers. Between mailing lists, info harvesting, and iLok I can see why the pirate scene for VSTs and samples is thriving.
