You can fix Yahoo Mail Not Sending Emails errors by following these troubleshooting tips. Therefore, you should try all points and see which one works best for you:

Check If Yahoo Server Is Down

The problem is not related to the end of Yahoo. By doing so, you will be able to determine if something is wrong with the Yahoo server or if everybody else has the same issue.
During Server downtime, you will not be able to send emails from Yahoo. That may be the reason why the Yahoo email account is not sending emails.

Check The Network Connection

Yahoo mail is a web-based service, so an optimal network speed is essential for Yahoo to function properly.
If you are experiencing problems with your internet or Wi-Fi connection, you won’t be able to send an email from Yahoo. Consequently, the network issue could be resolved by switching your network connection. Further, you should restart your router, or contact your Internet Service Provider.

Update Yahoo App

Users who do not update their app are likely to experience “unable to send email from yahoo account settings” problems. Make use of Yahoo to the fullest extent possible by updating the app.
Therefore, if you have trouble sending emails from Yahoo, you should update your Yahoo mail. Aside from that, if you are already using the latest version of the app, you should uninstall and reinstall it.

Check the Size of the Attachment

Yahoo limits the size of attachments in emails to 25 MB. Emails with attachments larger than 25 MB may be prevented from being sent by Yahoo. Therefore, if there are multiple attachments in an email, consider sending them in separate emails. With this approach, you can get around Yahoo’s attachment limit and send emails from Yahoo again.

Examine Sending Limit

Overspending the limit will create a barrier to your sending limit for the following 24 hours. Therefore, limit your daily email sending to 500 or fewer. Each recipient counts as one email, therefore sending one email to 20 recipients will count as sending 20 emails.

Inspect The Sent Folder

Check the “Outbox” folder to make sure that the email does not remain stuck. In case your email has not been delivered to the recipient, check your sent and outbox folders.
If you miss the “Send” button, check “Drafts” as there are times when your email ends up there.

The Spam Folder Of the Recipient Needs A Review

You may want to ask the recipient to check his/her spam folder. There is a possibility that your email has been filtered into their spam folder. If they are able to locate the email there, it means you are not experiencing any Yahoo mail-sending issues on your end.

Ask the Recipient to Unblock If Blocked

Sometimes, we accidentally block people without realizing it. Therefore, you should ask your recipient to check their block list and unblock you.

Check Email Address

Also, ensure you enter the correct spellings. For instance, “com” is not being typed as “con” or the @ is being placed correctly.

Check Yahoo E-mail Settings

You can configure Yahoo to work with other email clients, such as Gmail and Outlook. When Yahoo is configured improperly, you are likely to have a Yahoo Mail Not Sending Emails problem.
Hence, you should check your POP and Yahoo Mail IMAP settings and set them up to work properly with Yahoo. Here are the correct Yahoo settings:
