Folderly

Email deliverability tools are nothing new, but Folderly's specific 99.9% inbox rate claim caught my eye — that's the kind of bold number that either signals serious technical infrastructure or serious marketing fluff, and I'd need to see actual customer data before I decide which. Getting revenue from email campaigns is a genuine pain point for founders, but the space is crowded with tools like Mailgun and Postmark that have proven track records, so Folderly will need to prove it's not just another startup with big promises and no traction. The move here is for Folderly to publish real case studies with actual revenue lift numbers — anything less and this stays mid.
