Ecosystem. SimpleLogin is owned by Proton, so if you already use Proton Mail or Proton Pass, everything lives under one account. MailFlusher is independent — there's no bundled mailbox.
Native apps and extensions — today. Official browser extensions for Chrome, Firefox, and Safari, plus iOS and Android apps shipping now. We have Chrome and Firefox extensions and a mobile app in development, but they're not released yet — alias creation currently happens in the web UI or via API.
Brand recognition. SimpleLogin has been around longer and has a larger team behind it. If having a well-known brand matters to you, that's a real factor.
EU jurisdiction. We operate entirely from Sweden under GDPR. No US subsidiary, no CLOUD Act exposure. SimpleLogin is also outside the US, but our single-jurisdiction Swedish footprint is simpler to reason about.
Monthly billing. Our Standard plan is €1/month and Pro is €5/month — month-to-month. SimpleLogin Premium is annual-only at ~$30/year.
Deep power-user feature set. Advanced filtering rules, per-alias recipient routing, auto-create regex, multiple usernames for compartmentalization — MailFlusher was originally based on Addy.io, inheriting its reputation as one of the most customizable alias services on the market, and has been heavily extended since.
Burner aliases, leak attribution, and tracker stripping. MailFlusher ships three privacy features SimpleLogin doesn't offer today: auto-expiring "burner" aliases (by time or email count), per-alias leak detection that flags when an unexpected sender shows up on an alias you only ever gave to one brand, and an opt-in pixel + link-proxy tracker stripper that removes 1×1 tracking images and rewrites UTM/click-tracker parameters before they reach your inbox.
Independent operation. No parent company, no acquisition risk, no product-bundling pressure. Just email forwarding done well.
If it's not for you, pick SimpleLogin and walk away. We won't make it hard to export your data or cancel.
