Email deliverability checklist: SPF, DKIM, DMARC, BIMI in 20 minutes

The 12-item checklist that gets you to 98%+ inbox placement, with self-serve wizards for every DNS record.

Bad deliverability silently kills email programs. Here's the audit + fix workflow OmniMark customers use to get from 70% inbox placement to 98%+.

SPF

Add a TXT record: v=spf1 include:_spf.omnimark.pro -all. Use ~all during rollout, switch to -all after 7 clean days.

DKIM

Settings → Email → DKIM Setup generates a 2048-bit key + the exact CNAME to add. Verify green in /email/dkim-status.

DMARC

Start at p=none for 14 days to collect reports, then escalate to p=quarantine, then p=reject for full enforcement.

Warmup schedule

New IPs need a 45-day warmup ramp (10 → 50 → 200 → 1k → 5k/day). Skipping warmup lands you in spam permanently.
