Do not change a healthy system for the sake of it
If the problem is isolated to one provider or one part of the audience, we deal with that problem instead of rebuilding everything.
About Email Foundry
Email deliverability is rarely fixed by changing one setting.
Email Foundry is built and run by Nath Jackson. The service focuses on the awkward problems that sit between the sending setup, the audience and the mailbox providers deciding where the mail goes.
Why it exists
Passing SPF, DKIM and DMARC does not tell you why wanted email is going to junk.
A common pattern is that all the obvious checks pass, Gmail looks normal and Microsoft suddenly starts filtering a segment that mailed fine for months. At that point, changing subject lines or moving ESPs can create more noise without fixing the cause.
Email Foundry looks at the technical setup, audience quality, provider-level reputation and sending history together, then uses that evidence to decide what should change and what should be left alone.
How we work
A few operating rules we actually use.
Do not let machine activity make the list look healthier than it is
Privacy opens and security-scanner clicks are useful signals to identify, but they are not the same as a person reading or clicking an email.
Volume comes back when the evidence supports it
Recovery starts with the strongest genuine audience and expands as delivery, complaints, reputation and engagement improve.
Who we work with
Permission-based email only.
Email Foundry is for businesses emailing customers, subscribers, members and other contacts who have a genuine reason to expect the message.
