Everything you need to know before running your first audit.
Every audit scores your email against the 7-point Strategic Flow diagnostic — subject line, preview text, hook, visual hierarchy, before/after contrast, social proof, and CTA language. You receive a score, a named failure pattern, and a rebuilt version in HTML ready to paste into your ESP. Not suggestions. A finished email.
Copywriters work from a brief. Strategic Flow works from behavioral data. The audit diagnoses where in the reader's decision journey the email loses them — before a word of copy is changed. Most copywriters improve tone. Strategic Flow fixes architecture. Your copywriter writes better with the right diagnosis.
Yes. Every rebuild outputs HTML compatible with HubSpot, Mailchimp, ActiveCampaign, Klaviyo, Customer.io, Intercom, and every major ESP. No native integration, no engineering involvement. You receive the HTML — you paste it in. Your existing workflow stays intact.
Low send frequency usually means higher stakes per email. If one of those emails is your onboarding sequence or a product launch update, a single structural fix — subject line, hook, CTA — can recover the activation the email was losing every month. Run the free diagnostic first. If the score is below 5, the fix pays for itself.
Product update emails, onboarding sequences, changelog announcements, lifecycle emails, and newsletter issues. Strategic Flow also audits LinkedIn product posts and release notes. Any recurring communication where the reader needs to decide whether to act — that's the audit surface.
One full 7-point diagnostic, a named failure pattern, the rebuilt email in HTML, and 3 subject line variants with predicted open rate delta. Everything the monthly plans include — for a single send. The right entry point if you have one high-stakes email before a launch or a board meeting.
Cancel any time before the next billing cycle. No lock-in, no cancellation fee. Every rebuilt HTML file, audit report, and subject line variant you received stays with you. The work doesn't disappear when the plan ends.
Paste any email your company has sent. Full diagnostic in 60 seconds — score, failure pattern, rebuilt subject line. No card required.
