FAQ
Is IPQualityScore’s disposable-email detection as accurate as a specialized tool?
IPQS advertises 99.9% accuracy for email validation overall. Mailsurity’s 99.4% is measured on disposable detection alone. They are not directly comparable.
Why is IPQualityScore’s entry paid plan so much more expensive than Mailsurity’s?
You pay for four signals under one price. Mailsurity covers one signal. The lower price comes from a narrower product.
Can I run Mailsurity and IPQualityScore side by side?
Use IPQS for IP and phone checks, Mailsurity for email classification. They run independently. It is redundant only if you pay IPQS just for the email signal.
