# Folderly review

Email deliverability platform that diagnoses, fixes, and monitors inbox placement for B2B outbound teams.

By Noah — last updated & pricing verified October 23, 2026.

> 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.

## Facts

- Website: https://folderly.com
- Pricing: Free tier · paid from $79/mo (verified )
- License: Freemium
- Platforms: web
- Best for: B2B sales and RevOps teams sending high-volume cold outbound email who need to test and maintain inbox placement across many mailboxes
- 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.
