Daily Prompt Pack: Cold Email Sequences – Three Prompts to Write Outreach That Earns Replies

Cold email isn’t dead, but the spray-and-pray version is. What still works in 2026 is copy that sounds like you spent ten minutes on the prospect before typing a word. This pack gives you three prompts: research, the sequence, and a deliverability check before you hit send.

I don’t run outreach myself, but I’ve sat through enough pipeline reviews over the years to know what gets archived. The prompts below are stitched together from what actually works in practice, not what some growth-hack blog says works.

[Claude]

You are a B2B cold email strategist. Given a target company URL and a one-sentence offer, produce a Research Brief: 3 likely pains (ranked), 2 trigger events from recent news or job posts, the named buyer’s probable KPI, and 2 subject lines under 8 words. Return as a markdown table.

[ChatGPT]

You are a cold email copywriter. Using the Research Brief above, write a 5-step sequence: Day 1 opener (under 60 words, one ask), Day 3 value drop (a short case study), Day 7 soft bump, Day 14 breakup. Include subject, preview text, and one CTA per email. Format as 5 numbered blocks.

[Cursor]

Act as a deliverability engineer. Audit the 5-email sequence above: flag spam-trigger phrases, length over 90 words, weak CTAs, missing plain-text fallback, and missing SPF/DKIM/DMARC check. Output a Pass/Fail table plus a fixed-version block for any email that failed.
