Why this blog
Source-grounded, no fluff.
The pillar guides at /guide/email-deliverability and /guide/email-marketing-cost-savings are the long, stable references. The blog is where shorter, dated material lives — concrete tutorials, post-mortems, regulatory updates, release notes. Each post is dated and revisable: when an RFC update or a vendor pricing change lands, the affected post gets a fresh updated_date rather than a new post.
Subscribe to the RSS feed if that is your reading style. Otherwise check back — cadence is two posts per month, scaling to four after the first quarter.
