I understand the reason for this. I my case I use Brevo to send books from Calibre and Calibre web to my Kindle - I am not a mass mailer. I have added the [t-sender-sib.com](http://t-sender-sib.com) address to my Amazon approved senders list and still receive the books, but I realise this is temporary. I don’t have a domain to authenticate. Is there any way I can continue to send my books using the old gmail address? Or is there another easy solution for my use case? ---

Hi @John , thanks for posting on this community! The old gmail address won’t work, as per the Google and Yahoo requirements. I’m trying to think about it but I believe you don’t have any other choices than having your own domain, unfortunately. To give more context about this topic to our readers: - if you’re not sending emails from a domain that you own, Brevo is temporarily replacing your sender by [t-sender-sib.com](http://t-sender-sib.com) , so that your emails can be properly delivered - this is related to the new requirements from Gmail and Yahoo, explained in this article: [https://help.brevo.com/hc/en-us/articles/14925263522578-Prepare-for-Gmail-and-Yahoo-s-new-requirements-for-email-senders](https://help.brevo.com/hc/en-us/articles/14925263522578-Prepare-for-Gmail-and-Yahoo-s-new-requirements-for-email-senders) ---
