Every message is read. Reported calculation errors are fixed first.

What to write about

An error in a calculation. Include the numbers you entered and what you expected. These get fixed first.
Something that reads as wrong or out of date. Servicer rules change and pages go stale.
A calculator you wish existed. Requests genuinely shape what gets built next.
Advertising or partnership questions.

What we cannot help with

We cannot review your individual loan, tell you whether to recast, or contact your servicer for you. We are not a lender, a broker, or a licensed advisor, and questions about your specific situation belong with your servicer or a licensed professional.

Response time

Usually within a few days. Reported calculation errors are prioritized over everything else.
