Analyzing your email…
1. Paste Your Email Content
Enter your email text directly into the tool — include links, formatting, and images if applicable.
2. See Real-Time Size Calculation
As you type or paste your content, the tool instantly displays the total size of your email in kilobytes (KB).
3. Optimize if Needed
Use the displayed size to decide if your email needs trimming for better deliverability and to avoid getting clipped in email clients.
The Free Email Size Checker Tool, analyzes the size, character count, and word count of email content you paste into the tool. It provides an overall score (A+ to F) based on the email’s size, along with metrics to help optimize emails for deliverability and performance. The tool is web-based, free, and requires no account.
The tool provides:
Overall Score: A grade (A+ to F) based on email size, with a description (e.g., “Excellent – Perfect Size”).
Total Size: The size of the email content in bytes, KB, or MB (e.g., “12.34 KB”).
Total Characters: The number of characters, including spaces and headers.
Word Count: The number of words in the email body, excluding empty spaces.
Email size includes the combined size of the message body, embedded images, and attachments. It’s measured in kilobytes (KB) or megabytes (MB), counting all parts that make up the email.
Large emails may not be delivered or could end up in spam folders. Keeping your email size small improves deliverability and loading times, especially on mobile devices.
The overall score reflects the email’s size suitability for deliverability:
A+ (<0.5 MB): Excellent – Perfect Size.
A (<1 MB): Very Good – Optimal Size.
B+ (<3 MB): Good – Acceptable Size.
B (<5 MB): Fair – Consider Optimization.
C (<10 MB): Large – Needs Optimization.
D (<25 MB): Very Large – Reduce Size.
F (≥25 MB): Too Large – Will Be Rejected. Smaller emails are more likely to be delivered successfully and load quickly.
