Most email programs test subject lines or wait for open rates. That wastes sends, budget, and momentum.
This post is about doing the hard decision before you send: validating whether an email (or sequence) will convert the audience it’s intended for.
The Marketing Email tool in Vect AI is built for that job. It’s a pre-send decision tool that helps you reduce wasted sends and improve ROI before any campaign runs.
What it does (job first):
Scores subject lines, preview text, and body for clarity, urgency, and conversion intent.
Flags weak hooks, vague CTAs, and personalization failures.
Simulates audience reactions against a saved brand profile to surface persuasion gaps.
Recommends precise edits and sequence adjustments (timing, cadence, follow-ups).
Checks deliverability heuristics and common conversion friction before distribution.
Saves named drafts/projects so teams can approve, iterate, and export CSVs for ESPs.
Who this is for: founders, growth operators, email leads, and agencies that run paid or high-impact email campaigns and need predictable outcomes — not guesswork.
Why this matters: it moves the decision earlier in the workflow so you don’t waste budget on poorly targeted sends or lose momentum to slow review loops.

I’m especially interested in feedback from people who run email at scale and would consider paying for better pre-send signals:
Which pre-send signals would make you cancel or push a send?
What level of specificity in recommendations would change your approval flow?
What ESP integrations or export formats matter most?
Happy to dig into signal sources, scoring heuristics, or integration options.
Very good product
