The KMT Stack vs Mailchimp.

Mailchimp is a good way to send email. Once you also need a CRM, website analytics and a way to connect them, you are assembling a stack. The KMT Stack is that system, already built, set up for you, for one flat price.

Which one fits

Choose the one built for the team you have.

The KMT Stack is the better fit if

You want one system, from a first website visit to a closed deal, instead of three tools and a connector.
Your sales team works from a pipeline, and marketing needs to see what it turns into.
You want it set up for you, with a senior marketing technologist alongside your marketer for the first 90 days.
You want your data on its own instance in Europe, never used to train AI.

Mailchimp is the better fit if

You mainly send newsletters and promotions, and your sales team does not work from a pipeline.
Your list is small: the free plan or Essentials costs a fraction of either option.
You sell through Shopify or WooCommerce and want ecommerce emails.
You want the biggest library of templates and ready-made integrations.

Who you need to hire

Somebody has to make the tools work together.

Mailchimp does email well. A growing company also needs a CRM for its pipeline, website analytics, and the connections that carry a lead from one to the next. Building and looking after those connections is real work, which is why Mailchimp offers its experts for “connecting apps, creating automations”. In most small companies it lands on the one marketer, on top of the marketing.

With the KMT Stack that work is part of the product and the launch. Analytics, marketing automation and the CRM arrive connected, one record per person. Grep answers your marketer’s how-do-I questions on the screen they are on and drafts the work when they ask. For the first 90 days, a senior marketing technologist works alongside them.

What that help costs elsewhere

$51,000 to $111,000
a year, the salary range for a marketing operations specialist in the US (Payscale, June 2026)
Included
with the KMT Stack: the setup, Grep, and 90 days alongside a senior marketing technologist

What you would assemble

Three tools and a connector, and still not one system.

In software alone, the tools cost less than the KMT Stack: about $264 a month at 10,000 contacts. What they do not add up to is the reason companies outgrow them.

The tools, per month

Mailchimp Standard, 10,000 contacts$135
A CRM for four salespeople (HubSpot Sales Hub Starter)$80
A connector (Zapier Professional, 2,000 tasks)$49
Google Analytics 4Free

TotalAbout $264 a month

What the set still does not give you

One record per person, from first website visit to closed deal
A known person’s website visits: Google Analytics may not store emails or names
Reports across email, the CRM and the website together
An assistant that works across all three
Someone to build the connections and keep them working

The KMT Stack: $950 a month, all of it included, set up for you.

List prices as of 19 October 2026, before new-customer promotions. Mailchimp counts subscribed, unsubscribed and non-subscribed contacts; at 100,000 contacts the same set costs about $929 a month. Setup and ongoing help are not included.

Questions owners ask

What is the KMT Stack?

The KMT Stack, from Keystone Marketing Technology, is one connected marketing and sales system (web analytics, marketing automation and CRM) with Grep, an AI assistant that amplifies your marketing and sales teams, for one flat monthly price. Your team signs into one place. KMT sets it up with you, and your marketer runs it with Grep, with a senior marketing technologist alongside for the first 90 days. See the KMT Stack.

Do we need to hire a specialist to run the KMT Stack?

No. The KMT Stack is software your team signs into and uses. Your marketer runs it with Grep, which drafts the work and answers how-do-I questions, and for the first 90 days a senior marketing technologist works alongside them. There is no administrator, agency or IT person to add.

Is Mailchimp cheaper?

In software, yes: Mailchimp Standard, a CRM for four salespeople and a connector come to about $264 a month at 10,000 contacts, against $950 for the KMT Stack. What that does not buy is the system: one record per person from first visit to closed deal, website analytics that know who visited, reports across all three, and someone to connect the tools and keep them working. With the KMT Stack all of that is included and set up for you, with 90 days alongside a senior marketing technologist.

Does Mailchimp have a CRM?

It has marketing CRM tools for managing your audience, but no sales pipeline, deals or sales tasks, so growing companies usually add a separate CRM and connect the two. The KMT Stack includes a CRM with a pipeline, connected to marketing automation and analytics, for everyone on your team.

Do unsubscribed contacts count toward Mailchimp’s price?

Yes. Mailchimp includes subscribed, unsubscribed and non-subscribed contacts in your plan’s contact count. The KMT Stack has no per-contact fees up to 100,000 contacts.

We have one marketer. Is the KMT Stack too much for them?

No. It is built for exactly that: a small team, often one person who does all the marketing. Grep drafts the work and answers how-do-I questions on the screen they are on, and for the first 90 days a senior marketing technologist builds the first automated follow-ups with them.

What moves across from Mailchimp?

Your contacts come across with their company links, and your forms are rebuilt in the platform and put on your website. The platform is usually live within the first week, and your team learns it over the first 90 days by doing the work alongside us.
