What this inbox is for
- Formula or bag-yield corrections — send the calculator URL, the inputs you used, the result you got, the result you expected, and a link to a manufacturer data sheet or extension page that supports the correction. Confirmed fixes go in the methodology correction log.
- Broken links, typos, or accessibility issues — a page URL and a short description are enough.
- Embed and partnership questions — tools marked embeddable may be framed on other sites when the credit link back to the matching YardTally page stays visible. Describe your site and intended use.
- Citation or source updates — if a manufacturer yield or extension depth guide changed, send the new URL. See also the methodology page for how sources are checked.
What to include
- The calculator or guide URL
- Inputs you used (dimensions, waste factor, bag size)
- Expected vs actual result when reporting a math bug
- Primary-source links (QUIKRETE / Sakrete data sheets, university extension pages, ICPI, etc.)
What we do not handle here
- Personal structural, engineering, or building-code advice for your specific site
- Quotes for ready-mix, landscaping labor, or material delivery
- Requests to invent fake reviews, credentials, or aggregate ratings
