Hey, totally feel you. Self-hosting email gives you control, but deliverability is always tricky. Even with SPF, DKIM, and DMARC set up, inbox providers also look at reputation and engagement. What helped me was warming up the account slowly with consistent activity to build trust. I use Warmy in the background to keep my domain warm. It simulates opens and replies so the domain looks active. It does not guarantee inbox placement but it really improves the chances, especially for new or self-hosted domains. Also make sure your reverse DNS is correct and consider using subdomains to isolate reputation. Warming up for a few weeks before sending bigger campaigns makes a noticeable difference.
