The cold email agency SOPs I wish I had written in month one: what to document before you take on your tenth client so month fifteen is not chaos

I run a cold email agency. Hit 25 active clients last quarter. Looking back, the period between client 8 and client 15 was genuinely chaotic because I had everything in my head and nothing written down. These are the SOPs that would have saved me three months of reactive firefighting if I'd written them in month one.
Inbox provisioning SOP. Step-by-step checklist for setting up new client inboxes through PuzzleInbox. Domain selection criteria, inbox to domain ratio, naming convention for accounts, how to connect to Smartlead or Instantly, how to verify DNS is passing before warmup starts. New inboxes never go live without a completed checklist. I burned two client domains in my first year by rushing provisioning and skipping verification.
Warmup threshold SOP. Specific criteria that must be met before any cold sends start. Minimum 14 days of warmup. GlockApps placement test showing 85% or higher inbox placement. SPF, DKIM, and DMARC all passing in MXToolbox. No exceptions for any client ever. This SOP alone has prevented more deliverability problems than anything else I've put in place.
List hygiene SOP. Every contact list through ZeroBounce before campaign load. Bounce rate review weekly per domain. If any domain hits 1.5% bounce in a week, the campaign pauses for a list audit. This one is unglamorous but absolutely critical to domain longevity.
Campaign launch SOP. Copy review checklist. Sequence approval by client. Sending volume calculation per inbox. First 48-hour monitoring schedule after launch. Reply handling setup confirmed before the first email goes out.
Monthly reporting SOP. Reply rate by campaign, bounce rate by domain, meetings booked attribution. Client-facing report template sent every first Monday of the month. This keeps clients confident and cuts down on the unscheduled check-in calls that eat your whole afternoon.
Document your SOPs before you need them, not after a client calls asking why their domain has a 4% bounce rate. The time you invest writing these down in month one pays back every single month after that.
