Postix — frequently asked questions
Are these tools free?
Yes. The ROAS, UTM, and engagement calculators run in the browser with no signup. They teach the formulas; Comet applies them to live journeys.
What is ROAS?
Return on ad spend is attributed revenue divided by ad spend. Comet Ads Manager shows it across Meta, Google, TikTok, and LinkedIn using your chosen multi-touch model.
Does Postix stamp UTMs on posts?
Yes. Scheduled posts and short links can carry campaign tags so Comet can stitch the click with the first-party pixel and CAPI events.
