not sure if this is considered a bug or not, but i thought i would
mention it. if you provide your email hash with uppercase hex values,
notify.io cant match it and returns a 403 Forbidden error. probably
easy enough to .tolower() the input just in case.
example:
works: 251171a6643a794e05827f88601918df
no worky: 251171A6643A794E05827F88601918DF
