Honestly， Levelsio's post today is the sharpest industry signal I've seen all week. Everyone's doing the math-Cloudflare comes in at nearly two-thirds cheaper than Postmark. For the past decade， email providers have charged a premium for two things： A better SDK， and more reliable delivery. Now both of those advantages are gone. Take a typical mid-to-large SaaS sending a million emails a month： Postmark charges $1，206. Resend： $650. SendGrid： $600. Cloudflare： just $354. And Amazon SES： as low as $100. The real kicker？ Levelsio dropped a complete migration prompt. Throw it into Cursor or Claude， and you can move your whole project's email system in ten minutes. What used to take a week of work from the ops team can now be done by a single developer in the time it takes to drink a coffee. The technical barriers are gone. The integration costs are gone. All that's left is price. He's already split his sending across three subdomains， and specifically warned： new IPs need a three-month warm-up-absolutely don't move transactional emails first. People stuck with pricier options like Postmark or Resend because it was easier. But now Cloudflare's pricing is near SES levels， while offering way better domain management and ecosystem experience. I've got a feeling every indie dev and small-to-mid SaaS will gradually migrate this way. Now that's what real infrastructure commoditization looks like.
