I just paid for a Basic Account. Can I send from more than 1 e-mail address.

I tried to add 2 more E-mail addresses, but the Zoho e-mail message sent to me did not have a button.

Zoho message said:

To verify the same, please click on the 'Confirm Email Address' button, found below. This link will expire in 7 days.

But no button was present.
