Your emails land in spam, get ignored, or never arrive - and you'll never know unless you test. ### Email Deliverability Problems Are Invisible Misconfigured SPF, DKIM, or DMARC means your emails land in spam - and there's no bounce, no error, no notification. They just vanish. Our email deliverability tester catches these before your prospects' inboxes do. ### Your Subject Line Decides Everything 47% of recipients decide whether to open based on the subject line alone. A weak subject line wastes every word that follows - and you'll never know it's the reason nobody replies. ### Generic Cold Emails Get Deleted Emails without personalization get 3x fewer replies. If your prospect can tell it's a template, they'll delete it without reading past the first line. ### A Vague CTA Means Zero Replies Every email needs a single, clear next step. Vague asks like 'let me know your thoughts' get ignored. Specific CTAs get responses. ### Spam Filters Work Against You Silently Words like 'guaranteed' or 'act now' send your email straight to spam. You'll never see it happen - your prospect just never responds, and you'll never know why. Our spam tester catches these triggers before you hit send. ### A Higher Email Score = More Replies A 10-point improvement on your email score can mean 2–3x more replies over a campaign. Testing before sending is the highest-leverage thing you can do. ## 10 Categories We Score Each category is scored 0–10, for a total out of 100. Here's exactly what our email tester checks. ### Deliverability SPF, DKIM, DMARC, and MX record checks on your sending domain ### Subject Line Length, curiosity, relevance, and open rate potential ### Opening Hook First sentence impact - does it earn the next line? ### Personalization Relevance signals that show this isn't a mass blast ### Value Proposition Clarity of what's in it for the recipient ### Call to Action Single, specific next step that's easy to say yes to ### Length & Format Readability, scannability, and appropriate length ### Tone & Voice Professional yet human - not robotic, not too casual ### Spam Risk Trigger words, patterns, and formatting that trip filters ### Standout Factor What makes this email memorable vs. the 100 others they got today [Test your email now - free](/tools/email-tester) ## Related Tools & Resources Improve every part of your outreach - from writing better emails to building your entire sales pipeline.

Skyp monitors this for every campaign, automatically. ## Frequently Asked Questions Everything you need to know about the free email tester. ### How does the email tester work? Paste your email or forward it to **score@grader.skyp.ai**. Our AI analyzes your subject line, body copy, personalization, tone, spam risk, and more across 10 categories. We also check your sending domain's DNS configuration (SPF, DKIM, DMARC, MX records). You get a detailed score report - usually in under 60 seconds. ### What does the email tester check? We score 10 categories: **Deliverability** (DNS and domain config), **Subject Line** (open rate potential), **Opening Hook** (first impression), **Personalization** (relevance to recipient), **Value Proposition** (clarity of benefit), **Call to Action** (next step), **Length & Format** (readability), **Tone & Voice** (professional yet human), **Spam Risk** (trigger words and patterns), and **Standout Factor** (what makes it memorable). Each category is scored 0–10 for a total out of 100. ### Is the email tester really free? Yes - up to 3 emails per day, no credit card, no signup. Just paste or forward your email and get your score. We built this as a free tool because most outreach fails for fixable reasons, and we want to help. ### What email score is good? **80+** is strong - your email is ready to send. **60–79** is good but has room to improve. **Below 60** means there are significant issues to fix before sending. Most cold emails we analyze score between 40–65, which means most outreach has easy room for improvement. ### Do you check email deliverability? Yes. We check SPF, DKIM, DMARC, and MX records on your sending domain. Misconfigured DNS is one of the top reasons emails land in spam, and most senders don't realize their setup is broken. Our deliverability check catches these issues before they cost you replies. ### What do you do with my email? We analyze the content and reply with your score. We don't store your email content after analysis and we don't share it with anyone. Your email is processed in real time and discarded. ### How is this different from other email testing tools? Most email testers only check deliverability - whether your DNS is configured and whether you'll hit spam filters. We do that _and_ analyze your actual email content: Is the subject line compelling? Is the copy persuasive? Is the CTA clear? Is the tone right? We score the writing, not just the plumbing. [Score my email - it's free](/tools/email-tester)
