Major Announcement: Email on Acid Joins the Pathwire Family


We’ve got some big news to share with you! Pathwire has acquired Email on Acid.

We’ll give you a moment to let that sink in ….

While you probably have a few questions right now, the first thing we want to let each and every one of our customers know is that you don’t need to worry about a thing. Your Email on Acid login isn’t changing, and you won’t be losing access to any features, but you will be gaining opportunities to empower your email marketing efforts.

Who is Pathwire?

Pathwire is a leading email deliverability service provider. If you haven’t heard of them, we’re willing to bet most email geeks are familiar with two of the company’s brands: Mailjet and Mailgun. Mailjet also created MJML, the open-source markup language that makes responsive email coding easy. Pathwire was formed as the parent company for these complementary services earlier in 2021.

Pathwire’s expanding Deliverability Suite helps email marketers solve complex communication problems. It offers a powerful email API that supports big brands such as DHL, Microsoft, and Lyft in delivering more than 240 billion emails every year. Pathwire’s goal is to help email marketers build connected experiences by providing reliable, cloud-native infrastructure, local expertise, and smart solutions based on machine learning.

A match made in email heaven?

Email on Acid already had a strong relationship with Pathwire before the acquisition. As an API customer, Mailjet integrates features of our email testing into its product set with a feature known as Inbox Preview.

But here’s the real reason why Pathwire and Email on Acid are such a great fit – our ultimate goals are in perfect harmony! Pathwire wants email marketers to “send smarter,” and Email on Acid strives to help you “deliver email perfection.”

By combining forces, we’ll have you covered across the board – from pre-deployment testing to getting campaigns delivered. That’s why we’re thrilled about what the future has in store for us … but even more importantly for our loyal customers.

Here’s what Pathwire CEO Will Conway had to say in the official press release:

“While having the world’s leading email API and innovative email marketing solution are one part of the equation to building a reliable path to the inbox, we wanted to go further. That’s why we’re thrilled to grow and expand our product offering to ensure nothing stands between your business and the inbox. With Pathwire and Email on Acid, building connected experiences just became easier.”

What can you expect?

We want to reiterate that Email on Acid customers won’t experience any disruptions or see any major changes right away. This is good news. It means we’ll be able to invest more in our product and offer our customers a more robust set of email marketing solutions in the months and years to come. For our CEO and co-founder, John Thies, Email on Acid was a passion project that started more than a decade ago. He knows you’ll be in good hands.

“One of the biggest challenges in email marketing is knowing how to manage the differences in which various email clients render campaigns. For 12 years, we’ve simplified that complexity with reliable email previews across dozens of clients and devices as well as a growing set of tools that help marketers deliver email perfection. Email on Acid is excited to join forces with the Pathwire team because our missions are directly aligned.”

John Thies, Email on Acid CEO

John and his sister, Michelle, started Email on Acid in 2009 and grew the company into the leader in comprehensive email pre-deployment technology. We’re now a recognizable name among email geeks across the globe, and there’s much more to come in the next chapter of our story.

With this acquisition, John Thies will be stepping down as CEO and moving on to new adventures. So, let’s all tip our hats to him as he rides off into the Colorado sunset!
