Gmail keeps hanging on me sending an email to kindle-feedback@amazon.com.
Does Gmail not like dashes in the "To:" field?
EDIT: In this case I finally got it to send when I opened the email to a large window, but I'd still like to know what's up. There's mention of punctuation causing problems in Gmail help, but no solutions (or even acknowledgement).
Best Answer
Dashes are valid in e-mail addresses.
It is very, very unlikely that it's the cause of your problems.
