Write an opening that earns the next sentence instead of restating the title

You are writing the introduction to a blog post. Its only job is to earn the reader's next sentence — not to restate the title, not to summarize the whole post before it's been read, and not to open with a throat-clearing statement about the general importance of the topic.

TITLE
Your Onboarding Emails Are Getting Ignored — Here Is Why

THESIS
Most onboarding sequences fail because they explain features in the first email instead of answering "why did I sign up."

AUDIENCE
B2B SaaS marketers who already run an onboarding sequence and assume the problem is subject lines, not sequencing.

WHERE THE READER IS STARTING FROM
They believe their open rates are low because of weak subject lines and have already A/B tested several subject line variants with no improvement.

HOOK MATERIAL AVAILABLE
A client's open rate went from 22% to 61% after reordering the sequence — subject lines were never changed.

TARGET LENGTH
3-4 short paragraphs, roughly 120-150 words

INTRODUCTION RULES
Never open by restating the title in slightly different words — if the title already told the reader what this is about, the first sentence needs to do new work, not repeat old work. Skip every throat-clearing formula: no "In today's world," no "Have you ever wondered," no "In this article, we will explore" — a reader who clicked already decided the topic matters; the intro's job is to prove this specific post is worth their next thirty seconds, not to re-argue that the topic exists. State the real stakes early — what changes for the reader if they get this right versus wrong — using the actual thesis, not a generic claim that could sit atop any post on this general topic. Use the hook material honestly: if it's a statistic, use the real number, not a rounded or dramatized version of it; if it's a story or example, don't add specific details you don't actually have just to make it more vivid — a hook that's slightly fabricated to be punchier is a credibility risk the moment a reader who knows the real numbers notices the gap. Address where the reader is starting from directly — agree with it, complicate it, or contradict it — rather than writing an intro generic enough to open any post on this topic for any audience; an intro that doesn't engage what this specific reader already believes going in is doing no persuasive work at all. Promise something specific the post will deliver, not a vague benefit — "you'll leave with the actual number that predicted churn in our data," not "you'll learn everything you need to know." Land the thesis, or a clear pointer to it, before the introduction ends — a reader should be able to state roughly what this post argues before reaching the first H2, not have to guess until the conclusion.

OUTPUT FORMAT
1. The introduction, at the target length.
2. One sentence stating which mechanism it uses to hook (a stat, a contradiction of a common belief, a specific stake, a story) and why that mechanism fits this audience's starting point specifically.
3. Confirmation that every specific detail used in the hook traces to the hook material provided, with nothing added or dramatized beyond it.
