How Much Does SaneBox Cost Per Year?

How much does SaneBox cost per year is a question that sounds like it wants a single dollar figure and doesn't have one. SaneBox charges by two things at once — how many mailboxes you connect and how many of its filtering features you switch on — multiplied by three possible billing periods. The result is a matrix, not a price.

This page walks the decision from one mailbox to four, describes the three plans and what each unlocks, and gives you a worked example so the annual bill lands somewhere you can predict. We build AI Emaily, a per-seat AI email client, so we spend a lot of time on competitor pricing pages; SaneBox's is one of the more honest ones, and one of the easier ones to misread.

The short answer#

SaneBox sells three plans — Snack, Lunch, and Dinner. Snack covers one email account and lets you switch on two features. Lunch covers two accounts and unlocks six features. Dinner covers four accounts and unlocks every feature SaneBox ships.

Every plan is billed monthly, yearly, or biyearly, with the yearly rate coming out to roughly a third less than paying month-to-month across a year, and the biyearly rate stepping down a bit further. A 14-day free trial runs before any charge, and — verified as of August 2026 on sanebox.com — no credit card is required to start it. Education, nonprofit, and government buyers get 25% off any tier.

So the annual answer depends on three choices at once: which tier fits your mailbox count, which features you want on, and which billing cadence you'll commit to. Get those right and the annual invoice is deterministic. Get the tier wrong and you're either overpaying or short a feature.

Criteria that actually decide the annual bill#

The annual figure isn't set by a slider on the pricing page; it's set by four decisions you make before you get to the pricing page. Answer these first and the right plan is usually obvious — the wrong ones fall out on their own.

• How many mailboxes do you need triaged, in twelve months' time? Snack tops out at one, Lunch at two, Dinner at four. Plan for the mailbox count you'll have next year, not this quarter — buying Snack today and migrating in month three because a second address showed up is more expensive than starting on Lunch.
• Which SaneBox features do you actually want on? Snack limits you to two, Lunch gives you six, Dinner gives you all of them. If your reason for buying is a specific pair — SaneLater to defer low-priority mail and SaneBlackHole to nuke a sender — Snack is enough. If SaneNoReplies, SaneReminders, the Digest, and SaneCC are also on the list, Snack is off the table.
• Monthly, yearly, or biyearly billing? The yearly toggle is roughly a third off the monthly rate, and biyearly steps down again. Both save real money, but both are paid up front for the full period. If you're still deciding whether SaneBox fits, stay monthly through the first cycle or two.
• Do you qualify for the 25% education, nonprofit, or government discount? SaneBox applies it to any tier for eligible buyers at signup, and it stacks on top of the annual-billing discount — the biggest single lever on the annual figure if you're eligible.

How SaneBox's plans scale from one mailbox to four#

The table below reorders the pricing page around the question buyers actually ask: which plan is my setup the customer for, and where does that plan stop being enough?

One shape the table doesn't make obvious: the tier steps don't only add mailboxes, they compound with features. Snack to Lunch is +1 mailbox and +4 features at the same time. Lunch to Dinner is +2 mailboxes and the remaining feature set. That coupling is why quoting a per-mailbox rate for SaneBox is misleading — you aren't just paying for more inboxes, you're paying for the ability to filter each of them more aggressively.

Worked example: a freelancer scaling from one mailbox to four#

In year one, Sam is a solo freelance designer with one Gmail address and wants SaneBox to defer low-priority mail with SaneLater and kill senders with SaneBlackHole. Two features, one mailbox — Snack is exactly the plan. On the yearly toggle, that's the smallest annual figure SaneBox sells.

In year two, Sam opens an LLC and adds an Outlook address for client work. Two mailboxes, and Sam also wants SaneReminders to chase unpaid invoices plus SaneNoReplies to see which pitches never got a response. Four features, two mailboxes — the plan is Lunch. Snack no longer fits on either axis; the annual figure roughly doubles, but so does the surface SaneBox is filtering.

In year three, Sam hires a virtual assistant with their own mailbox and adds a dedicated newsletter address. Four mailboxes, and Sam wants the full feature set on the assistant's inbox (Digest, SaneCC, SaneAttachments) plus the same triage on the newsletter address. That's Dinner. The annual jump from Lunch to Dinner is real, but it's the last one — a fifth mailbox is an add-on to Dinner rather than another tier.

That Snack → Lunch → Dinner progression is exactly the pattern SaneBox's tier design assumes. If you already know you'll be at four mailboxes inside twelve months, buying Snack this month is a false economy — you're going to migrate twice.

Red flags to catch before you commit#

Four packaging quirks trip buyers up on their first read of the SaneBox pricing page. None are hidden — they're all on the page — but none are obvious either, and each one changes the annual figure.

• "Pick 2 features" on Snack means two, not two categories. SaneLater alone is one feature. Turning on SaneReminders on top of it makes the count two. Wanting SaneBlackHole as well is where Snack stops working and Lunch starts. Read the feature list before you buy Snack, not after.
• Mailbox counts are inflexible below Dinner. Snack is one, Lunch is two — you can't buy "Snack plus a second mailbox as an add-on" cheaper than upgrading to Lunch. Extra mailboxes above four are available on request to SaneBox support (per their own help centre), but the four-mailbox ceiling on Dinner is where the published tiers stop.
• Yearly billing is roughly a third off monthly, but it's a full-year commitment. If your evaluation isn't over yet, monthly is the honest starting point. The savings from yearly are real; they're just not free money — they're the price of being sure.
• The 14-day free trial (confirmed August 2026 on sanebox.com) is generous and doesn't take a card, but SaneBox's own help centre still describes a shorter trial on one page. That's documentation drift on their end, not a bait-and-switch — the marketing site is the source of truth — but screenshot the trial length at signup in case there's ever a dispute about what you signed up under.

What we'd pick and why — the honest verdict#

The verdict has three shapes depending on how many mailboxes you're bringing and what you actually want SaneBox to do — plus one place where we, AI Emaily, are the better fit and one where SaneBox is.

If you're a solo user with one mailbox and a specific pair of behaviours you want automated (defer low-priority mail, blackhole a repeat offender), Snack on the yearly toggle is the cheapest way to buy exactly that. Don't over-buy tier for features you won't turn on; SaneBox's own trial is long enough to confirm which two you actually use before you commit.

If you have two mailboxes and use SaneBox seriously — the Digest, SaneReminders, SaneNoReplies, SaneCC — Lunch on yearly is the plan you land on. If you'll grow into a third mailbox inside twelve months, buying Dinner up front avoids a mid-year migration and is usually cheaper than paying Lunch monthly through the transition.

If you're at four mailboxes or want the full SaneBox feature set on every connected account, Dinner on biyearly is the lowest-cost-per-mailbox way to buy the product. Anything beyond four mailboxes is an add-on to Dinner and handled by their support team.

Where SaneBox is genuinely the better fit — and where we are. SaneBox has been at this since 2010, and its most durable advantage is that it works at the mail-server level: once you set it up, SaneBox filters your mail no matter which client you read it in — Apple Mail, Outlook, Gmail on the web, Thunderbird, iOS Mail. If your workflow depends on staying inside your existing mail app and just having smarter folders show up in it, SaneBox is built for exactly that and we are not — AI Emaily is a client, and you have to use our client to get our filtering. On the "works with any mail app you already use" axis, SaneBox wins.

Where we're the better answer is when the filtering isn't the goal, it's the starting point — you want an agent that also drafts replies in your voice, closes loops on your behalf under Copilot approval or Autopilot rules, and gives you an audit trail of every action it took. That job needs a client to live inside, and it's the one we build AI Emaily for. It's per-seat, with a 7-day free trial on Pro or Autopilot (card taken at signup, $0 if you cancel before day 7 — SaneBox's 14-day no-card trial is a friendlier starting surface if you're purely exploring). Current AI Emaily numbers live on our pricing page, and there's a side-by-side comparison against SaneBox if you want the head-to-head.
