Positive reviews:
“User friendly and stress free. It is really intuitive. You can have 0 experience with the tool and you can easily get used to it.” – Luis Fernando A. ⭐⭐⭐⭐⭐ June 16, 2025
“I find the platform practical, which has helped us speed up the process of creating digital material in my company. The tool allows you to create different templates in a practical way.” – Sarah R. ⭐⭐⭐⭐⭐ January 10, 2025
Negative reviews:
“The tool is generally pretty basic. The website says enterprise everywhere, but the way the interface is laid out, the lack of certain professional functionality anyone would expect (such as proper permissions, folders, error handling), it’s pretty clear this is a shoestring operation. They may have one or two big clients, but I can’t see how any real marketing organization could use this on an ongoing basis. It was kind of a bait and switch from what the website and salesperson said it was, to what it actually is. You can get something better for much less money by just using beefree.io.” – Verified User in Internet ⭐☆☆☆☆

Positive reviews:
“We leverage Knak to create all of our in-funnel emails and landing pages. It’s drastically improved the speed at which we can deliver new templates, emails, and landing pages without needing internal development expertise. Last year, with Knak’s help, we launched over 250 experiments across our funnel. All in all their technology is great, their team is incredibly helpful and they’ve played a huge role in the improvement of our prospective student experience.” – Tim Cerato ⭐⭐⭐⭐⭐
“Knak – A great solution with great support. We use Knak daily to develop email marketing materials for our Marketo instance and for our sales team as Outlook Templates in the field. It addresses the business problem of requiring an in-house coder or developer to create our Marketo emails.” – Akande Davis ⭐⭐⭐⭐⭐

Feature Highlights: What Stands Out and What’s Missing
Here’s a look at what Knak actually delivers – and where it falls short.
- Email Preview (Clients & Devices)
- HTML / CSS Validation
- Email Design & Rendering Testing
- Accessibility Checking
- Design Import
- Template Export / ESP Push
- Analytics & Reporting
- API Access
Let’s take a closer look at what Knak delivers with each of these features.
Email Preview (Clients & Devices)
60+ email clients are supported, with desktop and mobile options across light and dark mode. Ten clients come selected by default, and the list is easy to adjust from account settings.
HTML / CSS Validation
The Custom Validator integration sends email assets through an external validation service and brings the results back into the Knak interface. Configuration is handled in the Admin panel – API endpoint, auth header name, and auth value are all set there.
Email Design & Rendering Testing
Render testing sits inside the build workflow, so there’s no jumping to a separate tool mid-QA. Client, device, and dark mode checks all happen before the asset gets pushed to a MAP or ESP.
Accessibility Checking
Built-in ADA compliance checks, AI-generated alt text, and color contrast validation are all part of the standard build process. Accessibility doesn’t require a separate audit – it runs alongside the rest of the work.
Design Import
Figma connects directly to the Knak builder, cutting out the handoff step between design and production. Rebuilding a designer’s comp inside the ESP is no longer necessary – that step alone accounts for a significant portion of production time on most projects.
Template Export / ESP Push
One click pushes a finished asset to whatever MAP or ESP the team is using. No platform lock-in, and no manual code cleanup required on the receiving end.
Analytics & Reporting
Opens, clicks, and conversions are tracked post-send through Performance Insights, with support for Marketo, Salesforce Marketing Cloud, and Account Engagement. Having that data inside the same platform makes it easier to go back and see what actually moved the needle.
API Access
The Enterprise API connects to internal systems via webhooks, with status callbacks keeping teams in the loop. Custom MAP integrations, translation pipelines, and validation workflows each have their own documented endpoint specs.

Supported Integrations
| Integration | Brands Covered |
|---|---|
| Design Import & Approval | Figma |
| Template Export to Sending Platform | Marketo, Salesforce Marketing Cloud, Eloqua, HubSpot, Braze |
Design Import & Approval
The Figma plugin feeds designs into Knak as editable emails – layouts, fonts, spacing, and images all come through without a rebuild. Once it’s in, the marketing team picks it up from there and handles any final changes before it ships.
Template Export to Sending Platform
One click sends a finished email to the connected MAP or ESP. Marketo, Salesforce Marketing Cloud, Eloqua, HubSpot, and Braze are all supported, with each integration handling the platform-specific details – tokens, folder structure, naming conventions – rather than leaving that to the sender.
