Show HN: Free Transactional Email Plans – Live, Scraped Limits

[guilamu]

Working for a non-profit, I need to use as many free services as possible. Emails are part of it. Free tiers often change, hence this small tool.

I built it with Claude 4.5 (approximately 10 hours of work) with barely any coding experience. It generates daily a lightweight comparison of transactional email providers that only lists services with a renewable free tier, showing daily/monthly limits from live scrapes and clearly marking static fallbacks.

What do you think? Did I miss any providers that meet the "renewable free tier" criteria?
