“Before CustomerOS, we were finding out weeks after the fact that our emails weren't being delivered and our domains were toast.

We had no idea how many leads were falling through the cracks!

Once we switched to MailStack with Matt's guidance we haven't burnt a domain since, and our deliverability remains sky high landing us clients like Storyblok and Sequence.”

Thank you for building such an empowering tool, especially for designers! The site went from Figma to Framer in less than a week!

Playing around with @framer while building a landing page for a side project. I’m terrible at animations, but they make it so easy!

I’ve built pretty handy sites powered by Craft or WordPress in the past, but seeing @framer tackle CMS stuff so effortlessly is mind-boggling
