B2B SaaS

Prompt

Act as a Principal Infrastructure Engineer and ruthless B2B cold-outreach technician. I am offering a flat-fee technical subcontracting service to boutique cold email and B2B lead gen agencies: fixing DNS authentication (SPF include-flattening, 2048-bit DKIM, DMARC p=none + rua routing), provisioning secondary domains, and syncing mailboxes to Smartlead/Instantly. I have zero upfront budget, a single warmed Google Workspace outreach mailbox (capacity: 30 sends/day max, plain-text only), and I do not do live sales calls. Generate the complete, copy-paste operational toolchain in pure code and plain text across these 4 deliverables: 1. THE SCANNER SCRIPT (Python 3, zero external dependencies except standard libraries + dnspython): A lightweight terminal script that takes a target agency domain as input, queries its live DNS records, and evaluates: - SPF: Counts DNS lookups (warns if >8, flags if >10), detects missing includes. - DMARC: Checks for missing record, p=none vs quarantine/reject, and presence/absence of an aggregate reporting tag (rua=). - Custom Tracking Domain: Probes standard tracking subdomains (e.g., link., track., email.) to see if a custom CNAME is present or absent. - Auto-Pitch Generator: Formats the discovered defects directly into a 75-word, zero-jargon plain-text cold email draft addressed to the founder, citing their EXACT live defects as the hook. 2. THE AIRTIGHT 3-TOUCH SEQUENCE: Plain-text, conversational, under 90 words each, designed for a practitioner: - Touch 1 (Day 0): The live DNS defect findings + free fix offer. - Touch 2 (Day 3): The operational risk of SPF lookups/missing rua on client onboarding speed. - Touch 3 (Day 7): Break-up note offering a clean intake checklist. 3. THE ZERO-LIABILITY HANDOVER & SCOPE SPEC (Markdown): The exact text to send upon delivery: - Clear boundaries (what is covered vs. what is client error, e.g., copy quality, list hygiene, platform bans). - The objective delivery benchmark (MXToolbox / Mail-Tester 10/10 screenshots). - The 48-hour password rotation and admin ownership handover protocol. 4. THE ZERO-CONNECTS ESCROW & INVOICING PROTOCOL: The exact operational flow to bill a US/UK client upfront without buying Upwork Connects or paying platform registration fees, handling milestone protection safely via direct B2B invoicing rails. Give me pure execution assets only. No meta-commentary, no theoretical encouragement, no marketing fluff.
