When I changed my E-mail account, WordPress began sending me duplicate E-mails of my subscriptions as well as duplicates of some comments. This did not help my desire to simplify my life by getting all my blog activity into an E-mail account separate from my regular E-mails (you can throw in a few expletives at this point along with a temper tantrum).
It turns out that WordPress didn’t change over my blog subscriptions, they duplicated them. There truly were two sets of subscriptions out there. One was password protected and that was my actual WordPress account. The other one was not password protected and was merely a subscription manager that WordPress uses for a subscriber who is not part of WordPress.
When I changed my E-mail from Yahoo to Gmail, the Yahoo subscriptions were treated as a non-member subscriber. By clicking on the bottom of one of those E-mails, the subscription screen came up and I was unable to “unfollow”.
When I clicked on the bottom of the Gmail E-mail, it also came up with a subscription screen that had the same subscriptions. That I left alone as that was where I wanted my mail from.
It appears that responses to comments mostly switched over to Gmail. A few seem to be on my Yahoo account, but that is nearly run out. Those seem to mostly be older comments. I’m thinking I might not have been logged into WordPress when I made them and they are not part of my password protected WordPress account.
What a mess! I did put in a help ticket with WordPress, but they are backlogged right now and did not get around to it before I figured it out. It’s actually not difficult to correct but figuring out what was wrong took some persistence and detective work.

It must have been frustrating, because I am getting confused (at least this early in the morning) just trying to follow what happened! LOL! Glad you figured it out. ;)

Sorry Lynda. I probably need to re-write it and make it clearer. There’s nothing like posting it to see what I could have done better!
If this is something you want to do, let me know and I’m happy to help if you have problems.

I did that awhile ago…but I lost all my subscribes. So I had to go through and find everyone again. That was a bummer. So I feel for you!

That’s nasty. I was concerned about that too, but in the end it all worked out.

I feel your frustration, Nancy. I don’t like making those changes, too involved sometimes.

I really was sorry for a while that I even started it, but I really did want it out of my regular E-mail account. Now that it’s working, it’s great.

I am so glad you shared this as I was considering setting up an email account for my blogging. Now I know not to bother, at least not at this time.

It wasn’t hard once I figured out the problem. Now that it’s working, it’s helping a lot. If you do it and have problems, I’m happy to help.

I changed to a gmail account and it was nothing but a headache. Half the comments and other emails didn’t get through so I had had to keep going back to the original isp to clear the emails. And some came through twice.

It took me a while to get it straightened out, but it’s finally working right. I’m not a big fan of gmail, but I could no longer get a straight dogear6 account at Yahoo since I had the hyphenated ones.

I’ve just changed over to Gmail! I’d love to know if you’re still having problems with it…so far so good for me, but it’s early days.

I finally got it straightened out, but it was an issue for a while as WordPress created a whole second account that I had to delete.

They really haven’t worked out their email notifications very well, I think that’s the major problem!
Thanks for your email via my contact form, by the way. I replied – I hope you got the response! :)

Thanks so much for this post – you’ve helped me fix my duplicate email problem. I had to change over emails because the email server I had been using kept crashing. Now I’m using Gmail, and I see some people have had trouble with that :( We learn as we go, I guess. But anyway, appreciate you posting the solution…

You’re welcome! That’s why I wrote it up.
