The lead magnet thing is such a good example. It’s a clear and voluntary trade-off: you can have this free resource if you join my list, from which you can unsubscribe at any point. It can obviously be done in a scammy way, but you’re clearly not doing that. But some people think you should have to provide that resource without any restriction.
Or that forcing people who already opted in to do so again is fair, because if they don’t reconfirm, then they must not have wanted to be on the list. This is like a SaaS company calling every customer periodically to ask them if they might want to cancel.
It makes no sense, but the pro-GDPR crowd on HN in particular is very hostile to marketing in general and email marketing in particular.
No one here who likes the GDPR gives a shit about your business. They’ll be happy to give you bad advice based on how they wish the world was, and if it costs you dearly, that’s not their problem and you probably deserved it anyway.
I’m doing some of the same activities as you, and I personally will be changing basically nothing for GDPR. I’ve always treated customers fairly and I’ll continue to do so. Governments that have no jurisdiction or enforcement mechanisms against my company can pound sand.
