Field notes
Deliverability work rewards sequence: authenticate first (SPF, DKIM, DMARC in monitor mode), then clean reputation (remove compromise sources, warm properly), then enforce (DMARC reject). Skipping straight to enforcement without the monitor phase blocks legitimate mail, the most common self-inflicted deliverability wound we remediate.
Blacklist removal is 20% procedure, 80% forensics. Every major list publishes its delisting path; the hard part is proving the spam source is dead, because relisting follows surviving sources within days. Queue forensics, which accounts, which scripts, which auth failures, is the skill that actually ends listing cycles.
DNS is the highest-value boring infrastructure: one TTL plan executed before a migration prevents more downtime than any monitoring stack catches afterward. We treat every DNS change as a mini-migration with rollback math done in advance.
