BikeGremlin Yeah, because GDPR often means to share your (clients) data (to which emails belong) with as few third parties as possible. When I asked my lawyer about this he also recommended to keep things together at one host.
Since MyW's servers are hosted in Germany (Hetzner) that was even more pleasant to him.
But yeah, GDPR hinders a lot of "progress" and "features" I could make use of. Or at least makes it more difficult to leverage them, while the competition (outside and inside the EU) does.
