A pre-launch checklist for your first cold email campaign

Before sending: domains warmed and authenticated (SPF/DKIM/DMARC passing), list run through validation, daily volume starting small and ramping gradually rather than maxing out from day one, and a single copy variant tested on a small batch before scaling. Launching a brand-new domain at full volume with an unvalidated list is the single most common way to burn deliverability in week one.
