What happened
A developer shares a multi-month update after migrating from Gmail to Fastmail, finding the switch successful. Key tactic: using subdomain addressing (e.g., newsletters@sub.domain.com) so Fastmail auto-files emails into matching folders without manual rules, which proved better than Gmail's auto-sorting. They also note Fastmail supports up to ~100 domains per account, and that freshly registered custom domains may get greylisted by recipient email providers.
Why it matters
If you run a custom domain for email, subdomain addressing is a concrete organization strategy worth testing — it eliminates rule-creation whack-a-mole. Also be aware that newly registered domains face greylisting, so register and warm up your domain well before relying on it for transactional or contact email.
Discussion angle
Subdomain addressing vs. plus-addressing (user+tag@domain.com) — which holds up better for inbox automation, and does Fastmail's multi-domain support matter for founders juggling several project domains?
