Preflight Update: March, 2026

Hi! I’m Mark, founder of Preflight. Today, I’d like to share that the product is now live!

Preflight originally began as an exploration into making digital content more accessible. As the email testing product landscape has continued to become more and more hostile to individuals and smaller teams, I decided to steer my effort to building not just a better email testing product, but one that doesn’t burn a hole your pocket to use.

What’s available today?

• On launch, we bring you the ability to get quick insights into an email’s accessiblity, rendering, and some basic delivery analysis.

• See how your email will render in dark/light mode, different viewports, and in a handful of real email clients: Outlook for Mac; Apple Mail (Mac, iPad). We’ll be expanding this offering over time, but our insights I think will be valuable to you, today.

• Share insights. You can add additional users to your organisation to see the full insights and audits. Or for those that just want to share our insights, you can generate private links to share with colleagues and clients.

• English isn’t your native language? Preflight puede usarse en español. Puedes registrarte en español o cambiar el idioma preferido de la interfaz a español desde la configuración una vez que hayas iniciado sesión.

• A company you can trust. We’re a self-funded, bootstrapped company registered in Scotland (SC865033). I’ve been building and leading software teams in this product space for nearly a decade. And after being burned by the outcome of e-corps ruining great teams and products, my current aspiration is to build and sustain a small, focused team dedicated to creating a great product that delivers real value.

• A product you can trust. No throwing things over the wall to <flavour of the month> AI tool here.. Any static analysis, AI model analysis, or other analytical techniques are performed in-house by dedicated services we’ve built and own. We value your data and privacy, and don’t engage in selling of customer data to anyone.

What’s coming this year?

I have a lot of ideas, but I’m particularly interested to shape the product to fit our paying customer needs. But.. some of the things we are looking to do:

• Every 6 weeks, we’ll post and share news and updates to the product.
• More checks to improve our insights offering.
• More email testing devices. We will however be prescriptive, we don’t think you need to test in 110+ clients.
• Continue to iterate and improve the product experience.
• New tooling/product features to better enable teams to collaborate on work.
• A bunch of other cool stuff I need more hands to help build!
