Contact EFA National
EFA National is a small, independent site — there’s no support desk or ticketing system behind it, just an inbox that gets read.
support@efanational.com is the address for anything: a number that looks off in one of the calculators, a broken link, an idea for a tool the site doesn’t have yet, or a correction to something in the guides or Horse Museum.
What to include
If you’re flagging a calculator, say which one — the Horse Weight Calculator, Feed Ration Calculator, Horse Age Converter, Gestation Due Date Calculator, Hay Cost Calculator, or Stall Bedding Calculator — and the numbers you entered. That’s usually enough to reproduce whatever went wrong.
What not to expect
This isn’t a veterinary or farrier helpline, and nobody here can advise on a specific horse’s health, soundness, or a breeding decision — that needs a professional who can actually see the horse. Emails do get read, and genuine questions or corrections get followed up on, but there’s no guaranteed response time.
