  • Remails: A European Mail Transfer Agent
    An alternative is Lettermint[1] which has much more gradual (and slightly lower, but with a less generous free plan) pricing. It's also pretty new (I think it launched last year) but more fully featured. I haven't used it but it seems good. [1]: https://lettermint.co/. - Source: Hacker News / 7 months ago
