Ad overload. I don't mind ads, but your interface takes it to new extremes, especially when I try check a folder with no messages in it.

The new Yahoo Mail is horrible! Slower than the 7 year itch! No Block button! Why was it changed? It certainly is not an improvement! Horrible! Horrible! Horrible!

Stop interferring with my 'experience' by asking for feedback whilst I'm looking at my emails!

Until third-party ads stop being a significant source of malware, using an ad blocker is a smart, even necessary, protective measure. When you can assure me that it's not possible for a malicious ad to make its way into my browser via Yahoo or any ad network is uses, I'll be happy to add Yahoo to my whitelist.

Every single time I log in to my email since April 11, 2018, I have to accept or dismiss the new Yahoo Oath privacy terms. Please make that stop. I've accepted multiple times.

You used to be able to "filter" emails straight from the body of the email. Now there's not an option for that. Instead you have to open the settings, create a filter, going back and forth to the actual message to create the filter. Bring back the option of "filter emails like this" in the body of the email.

Please stop with the pop ups asking me for feedback please....

Terrible blurry font. Hard to read - makes me dizzy, like all of a sudden, I can't see. going back to the old version.

Give us a way to 'opt out' of the pop-up that keeps telling us that "you may have overpaid". I have no interest in the service. I pay for Yahoo mail. I'm sick of dismissing that pop-up!

Before the latest update, we could check any number of unread mails and hit "k" as a hot key to mark them as "read". Now we have to go through the drop-down to do it. Bring back the hot key!

old version allowed search by attachments, but this function doesn't work any more.

You need better spam filters. If I receive a legitimate email with bitcoin in the subject field, this is always followed by hundreds of spam emails related to bitcoin. Same for dating, any legit online dating emails are immediately followed by hundreds of dating spam.

I also have Gmail, and that never happens in their system.

Put a button on the new e mail sign in page offering a choice to stick with the new yahoo e mail or go back to the old e mail. THE NEW VERSION OF YAHOO E MAIL SUCKS A BIG ONE. Someone needs to be fired of this new POS

After being TRICKED into upgrading to the new mail without a way to revert.

I have noticed: 

1. No more bulk e-mail blocking. I can get like 30+ nasty an inappropriate junk sometimes.

2. Domain blocking has been disabled, I need that as said domains that are spamming do NOT care that spammers are mass spamming others. 

3. My filters both the organization wise ones and blocks mysteriously got wiped. I can't fix the block list without the @domain block access.

Make BLOCKING emails easier!

The checkbox in front of each email no longer works. When you click it, nothing happens. This has been happening since yesterday Nov. 8.

Stop messing with the e-mail system. It is was fine and worked great. Now it's nothing but delays, changes for no apparent reason. If something isn't broken, don't try to fix. Keep it simple and easy to use.

My idea is to make it easier to refuse this new set up and give me back my yahoo saved mail, you lost things that cannot be retrieved, this is unacceptable, as you have literally stolen my mail. FIX IT. and you little fix about hitting the setting button DOES NOT WORK !!!!!!!!

stop asking me for feedback its ******* obnoxious

If I wish to unsubscribe to a contact's email, I will do so. It is not helpful for you to list and offer to unsubscribe a contact's email for me.
