+
+Yahoo now enforces stricter security and authentication standards for senders.
+
+To ensure that your emails are successfully delivered, you must register your sending domain with Yahoo Sender Portal.
+
+You must log in with a Yahoo account (or create one) on the website https://senders.yahooinc.com/ and add the domain there.
+
+A code will be generated that looks like this (provided as an example, do not use it):
+
+<Message type="note">
+  **Here is an example of a code:** ```yahoo-verification-key=SknBkUiLwZ+qWdbCMOrp6FwRiV4bMZXXXXXXXXXXX```
+</Message>
+
+You will then receive the code to enter in your DNS settings.
+
+You can refer to other documentation on how to add DNS to your domain/web hosting.
+
+If you have any doubts about the DNS settings, please open a ticket and send us the code.
+
+<Message type="tip">
+  Activation may take up to 24 hours, and you can track the progress here: https://senders.yahooinc.com/feature-management/account-overview/#domains
