Email Setup

Why authentication matters

Email providers use authentication records to verify that you're authorized to send from your domain. Without proper authentication, your emails are more likely to land in spam or be rejected entirely.

Required DNS records

mB0t will show you the exact DNS records to add during domain setup. You'll need to configure three types:

• SPF — Tells receivers which servers are authorized to send for your domain
• DKIM — Adds cryptographic signatures to prove emails are authentic and unmodified
• DMARC — Tells receivers how to handle emails that fail SPF/DKIM checks

Setup process

1. Add your domain in the Domains section of the dashboard
2. Copy the DNS records displayed for your domain
3. Add these records to your DNS provider (Cloudflare, Route53, etc.)
4. Wait for verification—DNS propagation can take 1-24 hours
5. Check verification status in the dashboard

Best practices

• Start with DMARC in monitoring mode (p=none) before enforcing
• Verify all DNS records before sending at scale
• Monitor DMARC reports to catch authentication issues early
• Keep DKIM keys rotated annually for security
