When I attempt to address my email message by selecting a group and hit SEND I get the error message:

The address "seeminglygoodemail@example.com" in the "Bcc" field was not recognized. Please make sure that all addresses are properly formed.

If I select this particular email by itself it works. I've verified that the email is well formed.


It seems that the email address had a bad character that is not visible. Perhaps a Unicode 2-byte character that Gmail is displaying properly but storing as two bytes and tripping up its own parser.

The solution is to simply re-enter manually the email address.

  • I had to delete the to: field and re-manually type the email address then it sent. Thank you! – Tek Oct 6 at 14:34
