Why check your spam score

Testing your spam score is essential to make sure your email lands in the inbox rather than the spam folder. An email that trips a spam filter is never seen — no open, no click, no conversion. With Mailpro you can evaluate and improve every message using our built-in spam checker tool, right from your message list.

The tool gives actionable feedback and a final score, so you understand your email's likelihood of reaching the inbox — and exactly what to change to improve it. Better inbox placement means higher open rates, click-throughs and conversions.

QUESTIONS

Frequently asked questions

How is a spam score calculated?
Over 75% of a spam score is based on email content alone. Mailpro's checker evaluates spam trigger words, broken or suspicious links, image-to-text ratio, sender information and mobile formatting, then gives you a final score with recommendations.
Where do I run the spam check?
The free spam checker is available directly from your message list in your Mailpro account — use the "Check Spam" option to test before you send. See our FAQ on avoiding the spam folder.
Does a good spam score guarantee inbox placement?
A clean score greatly improves your chances, but deliverability also depends on authentication (SPF, DKIM, DMARC) and your sending reputation. The spam check is one important part of the picture.
