Best part is that mailX feels connected to real experience, not just a trend. This team has probably seen thousands of deliverability problems from the inside. That gives the product a different level of credibility. Excited to see this launch.
@campritchard mailX is not something we built because “AI agents” are trending. It comes from years of seeing the same email deliverability pain inside real teams. The goal was to turn that experience into something simple, fast, and usable by both humans and agents.
@campritchard Thank you to trust our team. We learned and keep learning many things about deliverability. Our experience with Mailwarm thought us a lot about how to build mailX
When emails land in spam, the visible problem is simple: people don’t receive them. But the real work starts after that. You need to understand why it happened. Is it the domain setup? The sending behavior? The content? The reputation? Something else?
I’ve seen teams waste a lot of time trying random fixes because they don’t know what to prioritize first.
That’s the gap we wanted to close with mailX: help teams understand what is hurting their deliverability and what they should fix. Email can still be one of the strongest growth channels, but only if it actually reaches the inbox ;)
After spending years around email deliverability from the technical side, one thing still surprises me: very small details can have a real business impact. A missing DNS record, a weak setup, or one bad configuration can quietly affect whether emails reach the inbox or not.
With more teams adding automation and AI agents into their workflows, this matters even more. Agents can send emails, trigger workflows, and move fast. But they also need clear signals when something is wrong, otherwise they can scale issues without anyone noticing.
That’s what mailX solves: making deliverability easier to understand, not only for humans, but also for AI agents that need structured, actionable answers.
Happy to answer any technical questions with the team today.
This is great. Ironically I just ran into this issue on my own agency email that's on Google. All was well but then I transferred the domain ownership from one website to another to consolidate where my domains are being held and this messed up the MX, SPF, and DKIM settings. Claude walked me through how to get it fixed but it was bad enough that I wasn't even receiving Resend emails from my apps or account verification emails. Would've loved to have this tool before yesterday!
@german_merlo1 Exactly, email is one of those fields that looks simple from outside, but becomes very deep when you start scaling. Appreciate the support!

我觉得很有趣的点是，越来越多的创业产品在做邮件自动化营销，会不会让我们的邮箱多了很多信息，导致这些信息后来又通过其他的方式直接进入了垃圾箱
