ROI reality check
Deliverability changes the economics quickly.
If authentication, reputation, or message quality drops inbox placement, the same spend produces fewer opens, clicks, and conversions. Model the revenue, then protect the sending setup.
Before scaling spend
Is this a forecast?
No. It is an estimate based on the assumptions you enter. Treat the output as a planning model, then validate with real campaign data.
Which costs should I include?
Include email sending costs, platform fees, list work, writing, review, and operations time. Hidden labor costs can change ROI quickly.
Where does deliverability fit?
Low inbox placement lowers every downstream metric. Use Folderly to monitor authentication, reputation, and placement before scaling volume.
