    It`s great you can validate straightly in Excel, however, it doesn`t always work properly. So, I would recommend using online services for that. There is a lot to choose from, I, for example, use proofy.io.

      You must work for proofy.io? $.006 for 1,000,000 records = $6,000 = CRAZY EXPENSIVE.

    It`s great to be able to validate emails straight in Excel, however, it doesn`t work out effectively sometimes. So, I think that the online tools may help. For example, proofy.io, which I, personally use.

    This doesn't validate emails at all.... I am still able to place spaces and returns in the field (in the middle and at the end) which negates the point for me.

    To correct this so it works for all domains, use: =ISNUMBER(MATCH("*@*.?*",A2,0)). Then it supports 2-letter domains such as ".ca" as well as complex domains such as ".co.uk" and "server1.company.com".
