I've been looking at protonmail, fastmail and mailbox.org. The latter being the front runner so far for pricing, features and storage (10gb vs 15), custom domain and catch-all. But I'll have to consolidate down some accounts to aliases as I was a bit greedy in g suites and had 14 accounts for various things.
I use Zoho mail. It gives you aliases and works well for a reasonable price.
