That lettermint service looks interesting! I was recently looking for something in that price range that covers both transactional and broadcast emails but couldn't find anything in Europe so I settled on Postmark which has been good, this looks almost identical in features and pricing though.
Same here. I just discovered this and put it in my "check out tonight" folder. I am currently happy using resend. But this looks interesting, especially also for my freelance clients with a focus on EU tech.
Yes, Lettermint looks great if you need both transactional and marketing emails. But it's a bit weird that the OP selected Lettermint over Scaleway for just transactional emails when they use lots of other Scaleway services.

[EDIT] Found the answer from the OP:
> To be honest I implemented Lettermint before I migrated to Scaleway, so I didn't even look at TEM
