You fixed SPF, DKIM and DMARC and email still lands in spam. Here's why.
Short summary
Email authentication (SPF/DKIM/DMARC) proves identity but says nothing about whether mailbox providers should trust you. Fresh domains default to suspicious because most new high-volume senders are junk, so deliverability depends on building domain and IP reputation through engagement signals over 45-60 days. Warm up by sending to your most engaged contacts first, ramping volume only while bounces and complaints stay near zero.
- •Auth records prove identity, not trustworthiness — fresh domains are guilty until proven otherwise
- •Domain reputation is built on engagement (opens/clicks), so send to your most active contacts first during warmup
- •Expect 45-60 days for a new domain to reach stable inbox placement; never mail cold lists on a fresh domain
