Maskmail Review (2026): Pricing, Features & Honest Verdict

TLDR

Maskmail is an email masking service that gives every website its own disposable alias and forwards the mail to your real inbox. The pay-per-email pricing is clever and cheap for quiet aliases, but risky if traffic spikes. Best for: low-volume privacy users. Price: from $0.99/mo plus $0.006/email, 14-day trial, no free plan. Rating: 6.3/10.

What is Maskmail?

Maskmail is what its makers call an email mask firewall. The idea is simple. Instead of handing your real email to every newsletter, store, and app, you generate a unique mask for each one. Mail sent to that mask forwards to whatever inbox you already use, and the second a service starts spamming you or leaks your address in a breach, you kill that single mask without touching the rest of your life.

Email aliasing is not new. Apple, Fastmail, and Mozilla have all shipped versions of it. What Maskmail bets on is pricing. Where most privacy tools charge a flat $4 to $5 per month, Maskmail charges a tiny $0.99/mo base and then meters you at fractions of a cent per email forwarded. We dug into the model and found it is genuinely different, and whether it saves you money depends entirely on how loud your aliases are.

The product is built around a Chrome extension and a web dashboard, so creating a mask while you sign up for a new service is a one-click affair. The pitch lands at a real problem. Most people reuse one or two real addresses everywhere, which means a single breach or a single sold list exposes their whole digital footprint. Maskmail’s answer is compartmentalization: every service is sealed off in its own mask, and a leak at one stays contained to one.

What Are Maskmail’s Key Features?

Unlimited masks with one-click kill switch

You can create as many masks as you want, one per service, and the standout is the instant kill switch. When a mask starts receiving spam, you disable it from the dashboard and the forwarding stops immediately. The address still exists so the leaking service keeps emailing into a void, but nothing reaches you. This is the core privacy promise and in our look at the product it works exactly as described.

Anonymous two-way replies

Plenty of aliasing tools forward incoming mail but fall apart when you try to reply. Maskmail handles two-way replies so you can answer an email and the recipient only ever sees the mask address, never your real one. That keeps the whole conversation behind the mask, which matters for things like marketplace listings or support tickets you do not want tied to your identity.

Custom domains and catch-all

You can bring your own domain and use catch-all support, so anything@yourdomain.com lands in your inbox as a mask. This is the feature power users care about, because shared-domain aliases can get blocked by some sites. Custom domain support is included rather than locked behind a higher tier, which is a point in Maskmail’s favor.

Delivery history and provider independence

Maskmail keeps a delivery history so you can see what each mask received and when, useful for spotting which service sold your data. It also works with any inbox you already have, including Gmail, Outlook, Proton Mail, and iCloud. You are not forced to move your email, which is the trap with Fastmail’s version of masked email. That provider independence is underrated: you keep your existing inbox, search, and filters, and Maskmail just sits in front as a forwarding layer you can switch on and off per service.

Spam control without collateral damage

The real payoff of one mask per service shows up when something goes wrong. If a store gets breached or a newsletter sells your address, you do not have to change your real email or set up fragile filters. You disable that one mask and the problem is over. Nothing else you signed up for is affected, and you instantly know which service was responsible because the spam can only have come through that one address. That clean, surgical control is the whole reason aliasing exists, and Maskmail executes it well.

How Much Does Maskmail Cost?

Maskmail starts at $0.99/mo for the base subscription, then adds $0.006 per email forwarded on top. There is a 14-day free trial with no credit card required, but no permanent free plan. The pricing is the whole story here, so it is worth doing the math.

If your masks barely receive anything, say a few dozen emails a month total, you might pay around $1 to $1.20 per month all in. That undercuts Firefox Relay Premium at $0.99/mo flat (which is already cheap) and beats SimpleLogin at $4/mo handily. The pay-per-use model is honest for people who create lots of masks that mostly sit silent.

The flip side is volume. If even one mask starts pulling heavy traffic, a newsletter you actually read, a busy marketplace account, the per-email charges stack up and the metered model loses its edge against a flat plan. addy.io, by contrast, has a real free tier and a $3/mo Pro plan with unlimited bandwidth, so heavy users have cheaper predictable options elsewhere.

It is also worth being clear-eyed about what a metered bill feels like in practice. With a flat plan you forget about it. With Maskmail you have a small running tab, and that changes behavior: you might hesitate before handing a mask to a chatty service, or check your usage to make sure nothing has spiked. For some people that is a feature, a nudge toward tidier email hygiene. For others it is a low-grade annoyance that flat pricing simply does not have. Neither is wrong, but it is the trade you are signing up for.

Who is Maskmail Best For?

Use Maskmail if you are a privacy-conscious individual who signs up to a lot of services and wants a unique throwaway address for each, but where those addresses rarely receive much mail. In that low-volume pattern, the pay-per-email pricing genuinely costs less than a flat subscription, and the kill switch gives you clean control over spam.

Skip Maskmail if you want predictable billing, if some of your aliases carry real ongoing email volume, or if free is the priority. Firefox Relay and addy.io both have free tiers that cover casual masking, and a flat plan removes the small anxiety of watching a meter. Maskmail is a sharp tool for a specific spending pattern, not a default for everyone.

Best Maskmail Alternatives

Firefox Relay

Mozilla’s Firefox Relay is the closest cheap rival. Premium is $0.99/mo (or $12/year) for unlimited masks, reply support, a custom subdomain, and even phone number masking, plus a free tier with 5 masks. It is a flat price from a name you can trust. If your aliases get any real traffic, Relay’s predictable bill beats Maskmail’s meter.

SimpleLogin

SimpleLogin is the privacy community’s favorite, at $4/mo or $30/year for unlimited aliases, unlimited custom domains, and PGP encryption. If you already pay for Proton, you get SimpleLogin Premium bundled in. It costs more than Maskmail’s base but includes encryption and a much longer track record, which matters for a security tool.

addy.io

addy.io (formerly AnonAddy) has the most generous free plan: unlimited standard aliases on the fly, plus paid Lite at $1/mo and Pro at $3/mo with unlimited bandwidth, regex rules, and self-hosting. For developers and anyone wanting free or flat-rate masking with no per-email worry, addy.io is the value pick.

Final Verdict: Is Maskmail Worth It?

Maskmail does one thing well: it makes email masking cheap for people whose aliases stay quiet. The $0.99/mo base plus pennies per email can undercut every flat-rate rival, the kill switch is satisfying, and not being locked into a specific inbox is the right design. For the right user, this is a smart little tool.

The reasons it lands at 6.3 rather than higher are real, though. The metered model introduces a small ongoing worry that flat plans do not, the company is young with a thin public track record, and there is no free tier when Firefox Relay and addy.io both offer one. Try the 14-day trial, watch your forwarding volume, and only commit if your usage actually fits the pay-per-email pattern. If it does not, a flat or free competitor is the safer call.

There is also a trust dimension worth weighing with any aliasing service. You are routing your incoming email through a third party, so the company’s longevity and security posture matter more than with most software. Mozilla and Proton have years of reputation behind them; Maskmail does not yet. That is not a reason to dismiss it, plenty of good tools start small, but it is a reason to keep your most important accounts on a provider you already trust and use Maskmail for the long tail of signups where a service folding would be an inconvenience rather than a crisis. Approached that way, Maskmail is a cheap, clever addition to a privacy setup rather than the foundation of one.
