Email Address Normalization

If you send unhashed email addresses to the Podscribe, the service normalizes the email addresses and then hashes them. If you want to hash the email addresses yourself before sending them, you must normalize them before you hash them.

Normalizing before hashing ensures that value will always be the same, so that the data can be matched.

To normalize an email address, complete the following steps:

Remove leading and trailing spaces.

If there are uppercase characters, convert them to lowercase.

In gmail.com addresses only:

If there is a period (.) in the address (ASCII decimal code 46/UTF-8 hexadecimal code 2E), remove it.

For example, normalize jane.doe@gmail.com to janedoe@gmail.com.

If there is a plus sign (+) with an additional string after it, before the @gmail.com, remove the plus sign (+) (ASCII decimal code 43/UTF-8 hexadecimal code 2B) and all subsequent characters.

For example, normalize janedoe+home@gmail.com to janedoe@gmail.com.
