My European stack: - OVH for object storage, domain names and simple Wordpress websites - Scalingo/3DS Outscale for PaaS (looking for alternatives here!) - Mailjet used to be EU but they've been acquired by Mailgun - don't know if that's an issue. Brevo is okay as an email service provider but they could be way better.

I think Mailjet is now owned by Sinch and Sinch is swedish?

Correct. Mailgun acquired Mailjet, then Sinch acquired us. We follow the EU data standards of our parent company for our EU products, which include Mailjet and Mailgun EU.

Mailersend is EU and fantastic

I got interested because i am looking to switch to european email service because of law requirements and i know MailerLite (their other product).

But after looking at their site: "MailerSend is a United States-registered company."

I understand they are based in EU but the main issue is that if they are registered in US then thanks to CLOUD Act afaik it doesn't really matter.

Might contact them about it, their mail servers are in the EU.
