My spam score is high — how to fix it
How to diagnose and resolve a high spam-risk score in CarcMail before launching a campaign.
A spam score above 3 is worth fixing before you send. Scores of 5 and above significantly increase the chance your emails land in spam folders instead of the inbox.
Overview
Your spam score is calculated from the content of your email — subject line, body, links, and formatting. A high score doesn’t always mean your email is bad; sometimes it’s a single specific phrase or an extra link causing the issue.
This guide walks through the most common causes of a high spam score and how to resolve each one.
Quick checklist of common causes
- Subject line contains high-risk words (free, guaranteed, urgent, act now, limited time)
- Email body contains promotional language or pressure tactics
- More than 2–3 links in a cold email
- All-caps words or excessive exclamation marks
- Very short email with only a link (looks like phishing)
- Heavily formatted HTML with lots of images (looks like mass marketing)
Step-by-step
Open the spam report for your campaign email
Go to Campaigns, select your campaign, and open the email editor. Below the editor, the spam score and a list of flagged items are shown. Read each flag carefully — they are written in plain language and tell you exactly what was detected.
Fix the subject line first
Subject lines are frequently the biggest contributor to high scores. Check for:
- Risk words: “free,” “guaranteed,” “no obligation,” “act now,” “limited time offer,” “you’ve been selected”
- ALL CAPS: “REPLY NOW” or “HUGE DISCOUNT”
- Too many exclamation marks: “You won’t believe this!!!”
- Overly vague subjects: “Follow up” or “Quick question” on their own are lower risk, but check if combined with risky body content
Rewrite the subject to be specific and benefit-focused without using sales trigger words.
Review the email body for spam phrases
Look for phrases that appear in bulk marketing and spam:
- “This is not spam” (ironically, this triggers spam filters)
- “Earn money,” “make money fast,” “increase sales,” “earn extra income”
- “Click here,” “click below,” “click now”
- “Special offer,” “exclusive deal,” “no cost,” “at no charge”
- Urgency language: “Don’t miss out,” “expires soon,” “respond immediately”
Replace these with plain, direct language. For example, “click here to book a call” → “If you’re open to it, here’s my calendar link: [link]”
Reduce the number of links
Cold emails should contain one link, maximum two. Every additional link increases your score.
Remove:
- Social media profile links in your signature
- Links to case studies or articles in the body
- Calendar links in the first email (put these in the follow-up after interest is established)
Keep only your primary CTA link.
Use AI rewrite to fix remaining issues
If your score is still high after manual edits, click Rewrite for deliverability. Give the AI specific instructions about what to preserve and what to fix. Example: “Keep the core message and CTA. Remove any phrases that might trigger spam filters and make the tone more conversational.”
After the rewrite, re-run the spam check to confirm the score improved.
Check email formatting
If your email was pasted from a document or email client, it may contain hidden HTML formatting that triggers spam checks:
- Clear all formatting and retype in plain text
- Avoid using tables, coloured text, or large images in cold outreach
- Keep the email plain and readable — it should look like a personal email, not a newsletter
How to confirm it’s fixed
- Spam score badge shows 0–2 after re-running the check
- The flagged items list is empty or shows only minor, low-weight flags
- The campaign setup page lets you proceed to the launch step
Common situations
| Situation | Likely cause | Fix |
|---|---|---|
| Score is 3–4 with no obvious flags | Combined weight of minor issues | Use AI rewrite with no specific instructions — it will improve overall quality |
| Score is 7+ | Significant spam content | Work through each flag manually before trying rewrite |
| Score improved but still above 3 | Remaining links or a persistent phrase | Remove all non-essential links and scan for any remaining risk words |
| Score is low but emails still go to spam | Inbox reputation, not content | Check inbox warmup status and domain authentication (SPF/DKIM) |
Content scoring is only one part of deliverability. Even a score of 0 doesn’t guarantee inbox placement if your sender reputation is poor. Combine clean content with proper inbox warmup for the best results.
