- IP warmup cannot be rushed
- Feedback loop setup requires ISP registration - Ubuntu 22.04 VPS with 2GB RAM minimum
- Domain name with DNS access
- Dedicated IP address (not shared)
- Port 25 open (many VPS providers block this) - Check SPF: dig +short TXT yourdomain.com
- Check DKIM: dig +short TXT mail._domainkey.yourdomain.com
- Check DMARC: dig +short TXT _dmarc.yourdomain.com
- Test with GlockApps before major campaigns - Day 1-7: 100-200 emails/day to highly engaged recipients
- Week 2: 500/day
- Week 3: 1,000/day
- Continue ramping until at target volume
