How Much Does Serif AI Cost? What to Ask Before the Demo

How much does Serif AI cost? As of July 2026 the answer has two halves. Most of it is published: Serif runs a public pricing page with individual tiers, a per-user Team tier, and a monthly or annual toggle. The top of the ladder is not. The Enterprise tier reads Custom, with a Contact Sales button where a number would be.

This page does not reprint Serif's figures. Third-party pricing pages for this product disagree with the vendor's own by a wide margin, and pricing here moves fast enough that a transcribed number becomes a liability within a quarter.

What you get instead is the part almost nobody writes: why a vendor quotes instead of publishing, why that is defensible rather than a trick, and the script for getting a real number out of a discovery call.

The premise of this post changed while we were writing it#

We planned this page around a finding from our own competitive research. In AI email, Serif was the clearest example we had of a vendor that routed buyers to a call instead of publishing a price list.

By the time we sat down to write in July 2026, that premise was out of date. Serif publishes a five-tier pricing page. We are saying so rather than shipping the post we planned, because a page claiming a price is hidden when it is not is worse than no page.

The useful part survived. Even with a published page, the moment your seat count or your security review crosses a line, you are in a discovery call and back to a quoted number. And the published tiers are separated by usage multiples rather than a stated unit, so the page gives you a price without telling you what you are buying.

What Serif publishes, and what still needs a call#

Splitting a vendor's pricing into published and quoted is the first move in any evaluation, because the two halves demand different work from you. Published means you can compare on a spreadsheet. Quoted means you have to run a process.

Here is that split as we read it on 29 July 2026.

Why a vendor would quote instead of publishing#

Quote-based pricing gets treated as a dark pattern in most comparison content. It usually is not. For a young B2B product it is a rational choice, and pretending otherwise makes the rest of a buying guide less trustworthy.

• A published number anchors permanently. Set it too low at launch and you cannot raise it without churning everyone who joined at the old rate.
• Value varies enormously by buyer. The same email agent saves a solo founder a few hours a week and saves a fifty-person sales team a headcount. One flat price makes the small buyer subsidise the large one.
• Enterprise deals contain real custom work. SSO and SCIM provisioning, a bespoke retention policy, a security questionnaire, a named onboarding contact. Those are hours, and hours are not a list price.
• Competitors read pricing pages. A funded incumbent can undercut a published number the week it appears. Withholding it is defensive, not manipulative.

What quote-based pricing costs you#

Being fair about the model does not mean absorbing its cost silently. Quoting moves work from the vendor onto the buyer, and it is worth naming which work.

• Time. Two to four calls before a number exists is normal. Shortlist four vendors, two of whom quote, and your evaluation gets weeks longer.
• Comparability. You cannot build a spreadsheet from a range, so a quoted vendor gets compared on rapport instead of on numbers.
• Information asymmetry. By the time a number appears, they know your team size, volume, budget cycle and urgency. You know none of theirs.
• Budget approval. Finance cannot approve a range. Without a figure to put in the request, the project stalls before the demo is scheduled.

How to run the pricing call#

The goal is one number, in writing, attached to a unit and a term. Everything else is context. Run it in this order.

1. 1

   Send your numbers before the call

   Email your seat count, monthly email volume and provider mix in advance. It removes the discovery half of the discovery call, and makes it harder to be told the price depends on details you already supplied.

2. 2

   Ask for the unit before the price

   Is this billed per seat, per connected mailbox, or per unit of usage? A price means nothing until you know what multiplies it. This category uses all three, sometimes inside one plan.

3. 3

   Convert usage into something you can count

   If the answer is usage, ask what one unit is in emails, replies or actions per month. Then ask what your own last three months would have cost. If nobody can compute that, the model is not ready to sell you.

4. 4

   Establish the term and the seat minimum

   How many months is the commitment, is it prepaid, and is there a floor below which you cannot buy? A low per-seat rate with a twenty-seat minimum is not a low price.

5. 5

   Ask what happens at renewal

   Specifically: is there an uplift cap in the contract, and does the discount apply for the whole term or only year one? Year two is where quoted deals quietly get expensive.

6. 6

   Ask whether the quote is indexed to volume

   If your volume doubles, does the price move mid-term or at renewal? If it halves, does anything come back? A quote that only travels upward is a one-way ratchet, and you should know before signing.

7. 7

   Separate the software from the services

   Get onboarding, migration, support tier and custom work itemised. Bundled numbers hide one-off costs inside what looks like a recurring rate, which distorts every comparison you run afterwards.

8. 8

   Ask for the list price and the discount

   What is the number before the discount, and what is it taken off? If there is no list price, the discount is not a discount. Say so pleasantly and keep going.

What a non-answer sounds like#

Most pricing calls fail politely. Nobody refuses to answer; the answer just never lands. Learn the shapes and you can push back in the moment.

How to get it in writing#

A verbal range is not a price. It cannot be forwarded to finance, it cannot be compared against a competitor's published page, and it does not survive the salesperson changing territory.

• Send your own summary within the hour. Write the number, unit, term and inclusions as you understood them, and ask them to correct anything wrong. People correct errors more readily than they volunteer commitments.
• Ask for a quote or order form, not an email. It should name the term, quantity, unit price, inclusions and renewal terms. If a field is missing, ask for it by name.
• Ask for the price to be held for thirty days. It costs the vendor nothing, and it tells you immediately how firm the number was.

Where we sit, and where Serif fits better#

Full disclosure: we build AI Emaily, so read this as an interested party with its limits on the table.

We publish every tier, and the reason is narrow rather than noble. Our pricing is simple enough to publish, so withholding it would only cost buyers time. That is not a criticism of vendors who quote; it is a difference in what the two products are at this stage.

AI Emaily is an AI email client with three authority levels: Manual, Copilot and Autopilot. In Copilot, nothing sends without your approval. Autopilot is gated, every agent action can be undone, and every action is written to an audit log you can read. It connects Gmail, Outlook and standard IMAP accounts into one inbox.

On drafting voice: replies come from a Personal Context you write yourself plus per-client profiles you set. We do not read your archive to build a model of you, and we do not train on your mail.

• Where Serif fits better: it works as an assistant layer on the mailbox you already use. If your team likes its current client and only wants triage and drafting added on top, an overlay is the right shape and we are not one. We replace the client.
• Serif's enterprise tier also covers SSO, SCIM provisioning and custom retention policies. If your security team needs those written into a contract, a vendor with a real enterprise motion is set up for that conversation in a way a self-serve price list is not.
• Our limits, plainly: the desktop app is a genuine download for macOS on Apple Silicon only and for Windows, built as an Electron shell rather than a native binary. There is no Linux build. Android is a PWA today, with the native app on the roadmap. Offline is partial by design — read and draft, but not a complete local archive.

The short answer, one more time#

Most of the answer sits on Serif's pricing page: individual tiers separated by usage, a per-user Team tier, monthly or annual billing, and a seven-day trial. The Enterprise tier is quoted, so that number depends on a conversation you have not had yet.

Quoting is a legitimate way to price a young B2B product. It is also a transfer of work onto the buyer, and preparation is the only defence. Bring your volume, ask for the unit before the price, pin the term and the renewal, and leave with a document rather than a range.
