Deliverability platform sold as separate products

What Folderly is
Folderly diagnoses why B2B email lands in spam — inbox placement, IP and DNS records, content — then fixes the root causes and keeps monitoring with real-time alerts rather than testing once. Two things are sold separately: the spam test, which has a free tier, and continuous mailbox health monitoring, which costs more than the test. SOC 2 and ISO 27001 are named on the site.
Pricing
| Plan | Price | What you get |
