One address, read by a person: hello@nxtolerance.com.

Most mail falls into two buckets — here’s what makes each kind actionable.

“A number on the site is wrong”

This is the mail we most want. If a result disagrees with your own arithmetic, or a wattage figure contradicts hardware you can measure, send:

1. the page and row involved (e.g. “the dishwasher row”),
2. what you entered — watts, qty, hours, days, rate,
3. what the estimator showed,
4. what you expected — your plug-meter reading, your nameplate, or your bill’s own math.

One honest caveat before writing: wattages are typical midpoints, not per-model promises. “My window AC pulls 850 W, not 1,000” is the estimator working as intended — the watts field is editable precisely because nameplates differ. Reports like “your dryer default says 3,000 W but DOE guidance centers closer to 2,800” are corrections; both are welcome, the second is the fix we’ll ship.

“An article is stale or wrong”

Each guide — watts→kWh, biggest power users, phantom loads, reading your bill — was written against public data (EIA surveys, DOE/ENERGY STAR figures, LBNL standby research) and rates drift. Quote the sentence, give the correction, and point at a source. Rate and share figures especially: if EIA publishes newer residential numbers, that’s a five-minute fix.

Suggesting a device or feature

Tell us the appliance and its typical wattage or duty cycle — “heat-pump water heater, ~500 W average” teaches more than “add water heaters.” Rows get added when they’re common enough to help more than one household and honest enough to label with a defensible figure.

What we can’t help with

Billing disputes, outages, and anything that requires your utility — we don’t have an account relationship with you and can’t act on your statement. For “why is my bill X?” the bill-reading guide plus your utility’s usage portal will get further than we can.

Expectations

No ticket system, no autoresponder. A crisp reproduction gets an answer within days; open-ended suggestions are always read, sometimes answered slowly.
