- Mail-merge add-ons - personalise from your mailbox, within its cap.
- Your own server - unlimited but hard to keep deliverable.
The best practices that keep you deliverable
- Only mail opt-in contacts - never buy lists.
- Authenticate with SPF, DKIM, and DMARC.

- Watch bounces and complaints, and prune dead addresses.
The honest truth: "free unlimited" always hits a wall - shared IP reputation or caps. A dedicated SMTP is what makes unlimited genuinely sustainable.
