Either you got a different email, or you are an imposter trying to make potential Swift Vet contributors gun shy about responding to Swift Vet email solicitations. I don't know you or have any reason to suspect this, other than the fact that the link from an email solicitation I just got was valid.
Solution: Everyone who wants to donate to the Swift Vets should get to the contributions page via the Swift Vets website.
I just did. Again. :)
Please post the bogus email.
