Can not receive verification codes from Digital Ocean

Can not receive verification codes from Digital Ocean

Hi, I can't receive emails from Digital Ocean, but I am able to receive emails from Zoho and from Gmail. I created an account on Digital Ocean using the email I created in Zoho. But it can't receive verification emails from Digital Ocean.

I have tested my other accounts on Digital Ocean on other email providers and they are receiving the verification code just fine. Please help as this is the main reason why I created the Zoho mails in the first place.

Thanks
