What is Folderly?
Folderly is a SaaS platform that helps companies keep their cold and marketing emails out of spam folders. It combines diagnostic testing (checking SPF, DKIM, DMARC, IP reputation, and inbox placement before a campaign goes out), ongoing sender-reputation maintenance, and real-time monitoring that alerts teams the moment an email lands in spam. It is aimed at B2B sales, marketing, and RevOps teams running high-volume outbound email who need their messages to reach the inbox.
Folderly is an email deliverability platform built for B2B teams running outbound and cold email campaigns. It bundles three tools: Folderly (core sender-reputation maintenance), Inbox Insights (a spam/placement, IP, and DNS test), and Pulse (real-time spam-placement monitoring with alerts to email, Slack, or SMS). The platform reports 4.8/5 on G2 and 4.9/5 on Capterra, and positions itself around a claimed 99% deliverability rate for customers.
Standout feature: Pulse: real-time spam-placement monitoring that alerts a team via email, Slack, or SMS the moment a campaign starts landing in spam, rather than discovering it after open rates drop.
Biggest weakness: Folderly's core product is priced per mailbox ($96/mailbox/month on the annual plan), which scales quickly for teams sending from many mailboxes, and it requires booking a demo rather than self-serve signup, unlike the Inbox Insights and Pulse tools which do have direct sign-up.
