djphilQ: Email Deliverability
How does the email deliverability work through your app? Is there a way to make sure it goes to their main inbox?

There’s no way to guarantee "main inbox" per say; email clients decide placement based on your domain reputation, authentication, content, and engagement. The best way to maximize inboxing is to follow deliverability best practices:
- Set up SPF + DKIM + DMARC (we require this to setup a sender in Dreamlit)
- Send from your own domain
- Keep lists clean (avoid cold/purchased lists, remove bounces/unengaged)
- Use good content hygiene (no spammy wording, balanced links/images)
- Include unsubscribe for marketing/broadcast emails
Hope this helps!
