Understanding Message Quality Checks in Leadvista AI

Learn how Leadvista AI checks every message for readability and clarity before it sends, and how to fix messages that get blocked.

Updated about 11 hours ago

Every message Leadvista AI sends goes through a quality check before it ships. This keeps your outreach professional, clear, and effective.

This article explains what those checks are, why they exist, and what to do when a message does not pass them.


Why quality checks exist

Leadvista AI checks every message for two things:

  1. Readability: Is the message easy to read? Complex language can confuse prospects.
  2. Clarity: Does the message sound natural? We remove corporate jargon and sales cliches.

These checks happen in the background. Every message the AI writes goes through them before it sends.


What is the FK score?

FK stands for Flesch-Kincaid. It is a standard score that measures how hard a text is to read. It maps to school grade levels.

  • Grade 1 to 5: Very easy to read (like a children's book)
  • Grade 5 to 7: Easy to read (like a news article). This is our target.
  • Grade 8 to 10: Fairly hard to read (like a business report)
  • Grade 11 or higher: Hard to read (like a legal document)

Leadvista AI aims to keep messages between grade 5 and 7. This is the sweet spot for professional outreach that feels natural and gets replies.

Tip: If your messages score above 7, they may sound too formal. If they score below 5, they may sound too casual. The AI adjusts for your Voice DNA, so a formal tone may produce higher FK scores.


What is syllable density?

Syllable density measures how many long words your message uses. A word with 3 or more syllables counts as a complex word.

Messages with high syllable density are harder to read. Leadvista AI flags them so you can simplify your language.

Example:

  • "I utilized the aforementioned methodology" has high syllable density (hard to read).
  • "I used the method we discussed" has low syllable density (easy to read).

Soft warnings vs hard rejections

When a message does not pass a quality check, one of two things happens:

ResultWhat it meansWhat happens next
Soft warningThe message is close to the limit but still OKThe message ships with a warning tag. You may see a note in your dashboard.
Hard rejectionThe message fails the check clearlyThe message does not ship. The AI tries again.

Think of it like a car dashboard:

  • A soft warning is like the check engine light. Watch it, but you do not need to stop.
  • A hard rejection is like the fuel light. Action is needed right away.

What happens when a message is rejected

When a message gets a hard rejection, Leadvista AI tries up to 3 times to write a better version.

Each attempt:

  1. Looks at why the first message failed
  2. Tries to simplify the language
  3. Checks again

If all 3 attempts fail, the campaign skips that touchpoint and moves to the next one. You may see an alert in your Slack or dashboard.

Tip: If your campaign produces fewer messages than expected, check your Voice DNA settings. A very formal Voice DNA can cause the AI to write messages that fail quality checks.


Common rejection reasons

ReasonWhat it meansHow to fix it
FK score too highMessage is too hard to readSimplify your language. Use shorter sentences and simpler words.
Syllable density too highToo many long wordsReplace complex words with simpler ones.
Forbidden phrase detectedMessage uses a banned corporate clicheRewrite without the cliche. Check the list of banned phrases in your campaign settings.
Ask pattern detectedMessage sounds like a hard sell or pitchRephrase as a natural conversation starter.
Personalization missingMessage does not include the prospect's name or companyAdd personalization tokens to your template.

How Voice DNA affects quality

Your Voice DNA tells the AI how to sound. If your voice is very formal (like a lawyer or executive), the AI will produce messages with higher FK scores. This is expected. It may cause more quality check failures.

Options to improve quality:

  1. Edit your Voice DNA: Make it less formal. Remove phrases like "gravitas" or "delivery leadership expert" if they cause issues.
  2. Add message instructions: In your campaign settings, tell the AI to use simpler language for this audience.
  3. Use thumbs-down feedback: When you see a message that is too complex, give it a thumbs-down. The AI learns from this.

What is next

  • Review your Voice DNA if messages are getting rejected
  • Train the AI with feedback
  • Check why a campaign is not sending
