The best 33Mail alternative
33Mail is one of the original alias services, auto-creating addresses on a personal subdomain. But its free tier is capped at 10 MB of mail a month and forwards in plaintext, the addresses carry your 33mail username, and there's no leak detection. EmailAlias adds clean domains, encryption, and exposure intelligence.
Why users switch from 33Mail to EmailAlias
Clean, Neutral Alias Addresses
33Mail puts every alias on yourusername.33mail.com, so the addresses visibly share a username that ties them all back to you. EmailAlias issues aliases on clean shared domains — or your own custom domain on Premium — so each one looks neutral and unlinkable.
Built-In Exposure Intelligence
33Mail forwards mail and nothing more. EmailAlias scores every incoming sender for phishing risk and alerts you the moment a high-risk sender hits one of your aliases, so you know exactly which signup leaked your address.
Encrypted, Not Plaintext
33Mail's free tier forwards in plaintext and caps you at 10 MB of mail a month. EmailAlias encrypts alias metadata with AES-256 at rest, runs a zero-knowledge pipeline — we never read or store your forwarded mail — and doesn't throttle your free inbound to a tiny monthly allowance.
A Modern Dashboard
EmailAlias gives you one-click alias management, visual analytics, and a browser extension to create aliases inline on any signup form — a step up from 33Mail's minimal, long-unchanged interface.
Feature comparison
A fair note about 33Mail
33Mail has been around since the early days of email aliasing, and its auto-create-on-the-fly model is genuinely convenient — hand out any address at your subdomain and it just works, no setup. Premium is also very cheap. If a simple, low-cost catch-all on a personal subdomain is all you want, 33Mail still does the job.
Pricing side-by-side
Both run a free and a paid tier. 33Mail's free Lite tier trades a 10 MB/month cap and a username subdomain for unlimited aliases; EmailAlias's free tier runs on clean domains with standard inbound limits.

How to switch from 33Mail in 5 steps
Subdomain aliases get re-issued; a custom domain just needs an MX change. Most people finish in under 15 minutes.
- 1
Create your EmailAlias account
Sign up at emailalias.io with the same destination inbox 33Mail forwards to. Start free with 10 aliases on a clean shared domain; custom domains live on Premium, which opens with a 7-day trial.
- 2
List your active 33Mail aliases
33Mail auto-creates aliases on the fly (anything@username.33mail.com), so check your 33Mail dashboard for the ones actually receiving mail and note which service each was given to.
- 3
Re-issue the aliases on EmailAlias
Because 33Mail addresses live on its subdomain, they can't be ported — mint a fresh EmailAlias address for each active service. If you used a 33Mail custom domain, add that same domain to EmailAlias (Premium), verify SPF/DKIM/DMARC, and re-create the local-parts so those addresses keep working unchanged.
- 4
Update your highest-value services first
Swap the contact address on banking, shopping, and primary-recovery accounts to the new EmailAlias addresses before the long tail. Send a test to each new alias and confirm it lands in your inbox.
- 5
Overlap, then retire 33Mail
Leave 33Mail forwarding active for 2–4 weeks while you update the remaining services. Once nothing new is arriving there, disable the old aliases (or close the account).
Frequently asked questions
The questions we get most often from people moving over from 33Mail.
Can I move my aliases between providers?
Aliases on a shared provider domain (e.g. @emailalias.io) aren't portable — they live on our domain and stay with us. Aliases on a custom domain (yourdomain.com) are fully portable: you keep the domain, point its MX records at a new provider, re-create the same local-parts on their side, and the addresses keep working — provided the new provider supports custom local-parts (most do; some only issue random codes). Custom domains are a Premium feature on EmailAlias, but for anyone who plans to use aliases long-term, it's vendor-independence insurance worth having.
What does Premium include?
Unlimited aliases, up to 5 custom domains, unlimited verified forwarding inboxes (so each alias can route to the right mailbox), send & reply from any alias, real-time leak detection with exposure analytics, and priority processing — all for $4/month or $35/year (save 27%).
What happens if a service I signed up for gets breached?
Because each service has its own unique alias, you'll know exactly which service leaked your data — when spam or phishing hits that alias, the source is obvious. Our exposure intelligence engine also flags suspicious senders in real time. Disable the affected alias and your real email stays safe.
Do EmailAlias aliases use a username subdomain like 33Mail?
No. 33Mail builds your aliases on a personal subdomain — anything@yourusername.33mail.com — so every address visibly carries the 33mail name and your chosen username. EmailAlias issues aliases on clean shared domains (and on your own custom domain with Premium), so the addresses look neutral and don't leak a username pattern that ties them all back to you.
How does EmailAlias's free tier compare to 33Mail's on limits and encryption?
33Mail's free Lite tier gives unlimited aliases but caps you at 10 MB of forwarded mail per month, with no anonymous reply, and forwards in plaintext. EmailAlias's free tier has standard inbound limits (not a tiny monthly cap), encrypts alias metadata with AES-256 at rest, runs a zero-knowledge forwarding pipeline, and scores incoming senders for phishing risk — which 33Mail doesn't do at any price.
Is EmailAlias free like 33Mail?
Yes, there's a free tier — 10 permanent aliases on clean shared domains, with a weekly high-risk exposure digest. 33Mail's free Lite tier offers unlimited aliases but on a username.33mail.com subdomain, capped at 10 MB/month and with no anonymous reply. If you want custom-domain forwarding from EmailAlias, that's Premium ($4/mo or $35/yr, 7-day trial).
Can I migrate my existing 33Mail aliases?
Subdomain aliases (on username.33mail.com) can't be ported — those addresses live on 33Mail's domain, so you re-issue them as fresh EmailAlias addresses. But if you used a 33Mail custom domain, you can move it to EmailAlias by repointing MX, re-creating the same local-parts, and every address keeps working without any sender learning a new one.
