The problem

You have four Chrome profiles for four email addresses.

One inbox per business. One tab set per life. Every email client was built assuming you have one job. You don't.

Portfolio entrepreneurs, solo founders, consultants, and holding-company operators all hit the same problem: the business structure gets more complex, but the inbox stays stuck on one identity.

How it works

One setup, every domain.

  • 1
    Add your domains. Paste the DNS records. The wizard verifies them and most domains are sending in under ten minutes.
  • 2
    Email arrives tagged. Every message wears a colored stripe matching the domain it was sent to — visible in the list, the message view, and the reply banner.

3 · The moment that earns the trial

Reply to a message sent to you@studio.com — the From is already correct. Override if you need to. Most days you won't.

No logos. Just operators using it.

Honest proof rather than invented customer-logo theatre. A live count, two unedited notes, and the date the press started.

Comparison

Why not just use Gmail aliases?

Aliases help you send from another address. They do not give each business a clean setup, a visible identity, and reply behavior that stays correct by default.

Everyone else

  • Google Workspacebilled per user, × every domain
  • Fastmailseparate inbox per identity
  • ProtonMailaliases are a footnote

Deliverability

Built for deliverability.

Email deliverability is the #1 reason people don't switch providers. Here's exactly how Emcognito WebMail handles it.

Per-domain DKIM
Your emails land in inboxes, not spam folders. RSA-2048 DKIM keys are generated when you add each domain. Private keys are Fernet-encrypted at rest.
SPF · DMARC
Receivers can verify your domain is allowed to send. The DNS wizard gives you SPF and DMARC records, including a p=quarantine DMARC policy.
Amazon SES outbound
Outbound email uses production-grade infrastructure. Sending runs through Amazon SES with threading headers set so Gmail and Outlook fold replies into the original conversation.
Bounces caught at the edge
Bad addresses stop hurting your sender reputation. SES feedback notifications mark dead addresses before a second email goes out.
Magic-link auth
There is no password database to leak. Sign-in links are one-time, fifteen-minute, and bound to the address they were issued to. Sessions use httpOnly refresh-token cookies.
30-day recovery
Deleted email is recoverable long enough to fix mistakes. Email moved to trash stays recoverable for 30 days before removal.

Founder

Yoni (Cigan) · founder

Emcognito WebMail exists because one person running several public products quickly ends up with several domains, sender reputations, and support addresses to manage.

Yoni built it for that portfolio-operator problem: one inbox for the work, with each business still keeping its own From address, DKIM signature, and context when it is time to reply.

FAQ

Questions before you switch.

01How is this different from Gmail aliases?
Gmail aliases are bolted onto a single-account inbox. Emcognito WebMail is built around multiple domains: each domain has its own color stripe, DKIM setup, and automatic reply From behavior.
02How much does it cost?
Solo is $3.50 per month or $2.99 per month billed annually for up to 3 domains. Studio is $15 per month or $12 per month billed annually for unlimited domains. Holding Co. is $39 per month or $29 per month billed annually for operators who want onboarding and priority support.
03Can I bring domains I already own?
Yes. Add any domain you control, paste the DNS records shown by the setup wizard, and Emcognito watches for them to resolve. Most domains are verified and sending mail inside ten minutes.
04Is my email actually going to be delivered?
Deliverability is the reason the product is built around per-domain DKIM, SPF, DMARC, Amazon SES outbound sending, and bounce handling. The deliverability section above explains the exact setup.
05Is my outbound mail DKIM-signed per domain?
Yes. Each domain gets its own RSA-2048 DKIM key, with the private half Fernet-encrypted at rest. The signature recipients verify belongs to the domain you are sending from, not a shared signer.
06Who is behind this?
Emcognito WebMail is built by Yoni (Cigan), the founder behind several small public products. He built it after living with the same portfolio-operator problem: too many domains, too many addresses, and too much risk of replying from the wrong identity.
07What happens if I cancel?
You stop being charged. Email you have already received remains yours, and magic-link sign-in keeps working through the end of the paid period. Nothing is held hostage.
08Do I need a card to start?
No. The first 25 sends and the first domain are free, no card required — long enough to actually live with the product. After that, every plan has a 14-day card-required trial that doesn't charge until the trial ends.
