The following I'm snatching from here. I have my blog set up to send comment notification to my email. I'd like to just hit reply to respond, but most other Blogger people must not have an email address associated with their blogs. So here's a little lesson about it.
1. Suzie leaves a comment on Jodi's blog asking a question.
2. Jodi has all her comments sent directly to her email.
3. Jodi checks her email and reads Suzie's question. Jodi clicks reply. Shazam! Up pops Suzie's name but instead of her email address, it say's NO-REPLY. Argh!
4. Suzie doesn't have an Email associated with her blog. So no one can reply to any of the comments or questions that she leaves. Boo Hoo.
You may not even know that you are a NO-REPLY blogger. No worries.
Follow these instructions to see if you are a NO-REPLY blogger:
Sign in to Blogger and bring up your Dashboard or Profile Page. Click on EDIT PROFILE.
See the third box down (SHOW MY EMAIL ADDRESS) there should be a check mark in it.
Scroll down; see the section titled IDENTITY. See the box labeled EMAIL ADDRESS. Your Email address should be in that box.
If there is no email in that box or if you don't have the Show My Email Address box checked. You are a NO-REPLY blogger.
#1 ARGUMENT often heard from NO-REPLY bloggers:
I DON'T want my personal email out there for the whole world to see....
Good News! You don't have to. You can set up a "generic" email address to be associated with your blog. (You just need to remember to check it often) (especially if you leave a comment or ask a question on another blog).
