Short answerChoose SimpleLogin if you want to reply from your aliases, use your own domain, or you already pay for Proton. Choose Hskky if you mainly want to receive mail privately and prefer a lower yearly price for custom alias names.

Where SimpleLogin is stronger
- Replies and sending. SimpleLogin lets you reply from an alias so your real address stays hidden in two-way conversations. Hskky aliases are receive-only.
- A more generous free plan. Ten free aliases against Hskky’s one.
- Your own domain. Premium supports custom domains and catch-all addresses.
- Open source and Proton integration. Useful if you value auditability or already live in the Proton ecosystem.
Where Hskky is stronger
- Lower price for named aliases. Plus is $20 a year compared with $36 for SimpleLogin Premium.
- A narrower, simpler product. Fewer settings to learn if all you want is forwarding you can switch off.
- Deleted custom names are locked forever. Hskky never reissues a deleted custom alias, which closes off password-reset takeovers through recycled addresses.
- A predictable lifecycle. Stopped aliases are held for two months, then removed, and the rules are written on the pricing page.
Using both
Alias services aren’t exclusive. Some people keep SimpleLogin for one purpose and use Hskky for another, for example a Hskky alias for shopping and newsletters that forwards to a different inbox. If you move existing accounts, update the email address on each account before you stop the old alias.
