I send the test email to www.mail-tester.com/ and use self hosted Kutt link shortner for any links that are considered “broken/spammy”. For example almost any link to medium.com articles are considered spam. I have no idea why

For data I use Airalo eSIM - it’s great www.airalo.com/

I used DeepL for English translations. I think this will be my workflow - writing in Polish, translating to English, proofreading and publishing 2 versions

Actually I send weekly UX newsletter, but in Polish (uxtygodnik.pl). I am thinking about branching to cater also the english-speaking audience
