Every marketer knows the feeling. You’ve just finished crafting an email campaign. You’ve tweaked the subject line three times, moved the CTA button twice, and spent 20 minutes debating whether to make the header text bigger or smaller. You hit send, fingers crossed that all those decisions will pay off.
We don’t actually know which of those changes will move the needle on opens, clicks, or conversions. We’re relying on hunches, outdated “best practices,” or whatever worked last time; even if last time was a completely different campaign for a completely different audience.
The trial-and-error approach wastes time, leaves performance on the table, and makes it harder to prove ROI. What if you could skip the guesswork entirely?
Introducing AI Email Booster: Your Campaign Copilot
We built an AI Email Booster to solve a simple problem: marketers shouldn’t have to guess what will improve their email performance.
AI Email Booster analyzes your draft emails and surfaces high-impact recommendations that actually move metrics: opens, clicks, and conversions. It lives right inside Campaign Monitor’s email builder, so you don’t have to switch tools or break your workflow.
No more wondering if your subject line is strong enough. No more second-guessing your CTA placement. Just clear, actionable guidance that helps you send better emails, faster.
What Makes AI Email Booster Different

It focuses on what actually matters
AI Email Booster doesn’t just throw generic best practices at you. It identifies the specific levers in your email that drive performance: subject line effectiveness, CTA clarity, readability, tone, link structure, accessibility, and spam signals.
Using in-builder analysis, it pinpoints high-value improvements tied to measurable outcomes. You’ll see the most impactful changes first, so you can focus your effort where it counts.
It saves you hours of manual work
How much time do you spend hunting through content blocks to adjust formatting? Or manually rewording copy to improve clarity? AI Email Booster eliminates that friction entirely.
Each recommendation includes an “Apply change” button. Click it, and the improvement is instantly applied to your draft. No tedious editing. No copy-pasting. No switching between tabs to look up best practices. The assistant handles the heavy lifting, so you can spend less time on repetitive tasks and more time on strategy.
You stay in control
AI help shouldn’t mean giving up creative control. AI Email Booster makes recommendations, but you decide what gets applied.
Every suggestion requires your approval. If you don’t like a change, use the built-in Revert option to undo it with one click. Each recommendation also comes with a short explanation of “why this helps,” so you’re making informed decisions; not just blindly accepting automation.
Think of it as a copilot, not an autopilot. AI Email Booster assists your judgment; it doesn’t replace it.
What AI Email Booster Checks For
Every time you open AI Email Booster in your draft, it analyzes your email across multiple dimensions:
- Subject line effectiveness – Is it compelling? Does it avoid spam triggers?
- Call-to-action clarity – Is your CTA prominent and action-oriented?
- Readability and tone – Is your copy clear and appropriate for your audience?
- Link structure – Are your links working correctly and logically placed?
- Accessibility – Do your images have alt text? Is your formatting screen-reader friendly?
- Spam signals – Are there phrases or patterns that might hurt deliverability?
- Content hierarchy – Does your layout guide readers toward the most important information?
The result? More polished, professional campaigns that respect your brand voice while performing at their peak.
