MailerCheck

Reach the inbox and boost your deliverability by verifying, analyzing and cleaning your email lists. MailerCheck is an email deliverability platform that provides businesses with tools to improve their campaigns and email configuration for maximum delivery performance. The email verification tool allows users to check a single email address or an entire contact list. It detects invalid or problematic emails so they can be removed, preventing damage to the sender's reputation and improving their chances of successful delivery.

Pros

    IPQS

    IPQS is a fraud prevention and threat intelligence platform that helps businesses detect and stop fraud in real time. Device fingerprinting, IP reputation analysis, and email and phone validation combine into actionable risk signals that prevent account takeover, fake account creation, payment fraud, bot abuse, and other forms of online fraud. The difference is the data. Over 10,000 honeypot sensors across the web feed exclusive intelligence on human-like bots, residential proxies, low-quality emails, and stolen user data — updated continuously rather than on a monthly refresh.
