Hosting guides, infrastructure deep-dives, and email deliverability from the team that's been running servers since 1992.
DKIM keys are supposed to be rotated periodically. Almost nobody does it. The ones who try often break their email for a few hours doing it. There's a correct procedure that avoids both problems, and it's surprisingly unglamorous.
Selling DMARC monitoring to a client who's never heard of it is one of the easiest sales conversations you can have in professional services, assuming you frame it correctly. The problem is that most agencies frame it wrong.
In October 2023, Google and Yahoo jointly announced new requirements for anyone sending more than 5,000 emails a day to their users. The rules were to take effect in February 2024. They were, at the time, the biggest change to bulk email deliverability in more than a decade.

It generates £500-1,500 per engagement, takes about 3-4 hours of actual work, and has an extremely high conversion rate from the first conversation because the value is obvious and the price is low. It also leads directly into a £50-150/month recurring monitoring service, which is where the real margin is.
cPanel pricing changed in 2019. Since then, reseller margins have been squeezed year after year. Here's how Enhance compares — from a host that actually operates both.
Three records. Three different jobs. Most guides treat them as a checklist. This one explains what actually happens when each one fails — and why all three must work together.
Shared hosting has historically meant PHP. Enhance changes that with native Node.js app support. Here's what actually works, what has limits, and when Node workloads need a VPS.
Most email deliverability problems aren't content problems. They're infrastructure problems — a PTR mismatch, a DMARC policy set to none, a shared IP on a blacklist. Here's what's actually going wrong and what to do about it.
The team behind FXRM has been running email infrastructure since the early 1990s — from MMDF and Sendmail to Postfix and Zimbra. Here's what actually matters for getting mail delivered.
