Force email addresses in lowercase

Hi all,

I am thinking about add a transformation in our recipients import workflows in order to force all email addresses to be in lowercase. What do you think of this initiative? Can you see any drawback?

Thanks a lot

Guillermo

    Hi,

    Email addresses are case-insensitive. There is no drawback to converting to lowercase, except the loss of (useless) information in the process. No real benefit either fwiw.

    Thanks,

    Hi Guillermo,

    I think all the email addresses in the recipient are lowercase by default.

    Are you sure the email addresses are in uppercase if any chance?

    Regards,

    Venu

      Hi Venu, and thanks for your reply.

      In my case they are normal strings, so they can be either lower or uppercase, depends on the input when the record is created. That's why I am thinking on adding some governance on those.

      Regards

      Guillermo

        I know it's an old thread, but email addresses are case-sensitive – see RFC 5321 (https://datatracker.ietf.org/doc/html/rfc5321#section-2.4). That many email servers ignore the case of the local part is only a recommended approach, and not a universal standard by any means. Adobe changing the case of user's email address is undoubtedly a bug.

        By the way, I'm experiencing the same problem as OP.
