Two methods for you:
Today I am going to show you, how to generate over 1000 Gmails and use them for verification or other stuff.
You need one existing Gmail Account, once you have one you go to the website i linked for you below, and you put your email in the text box.
It will generate over 1000 G-Mails, they are now all linked to your original Gmail account.
You can paste the generated gmails everywhere for registration, but you will recieve your emails on your original account.
For this method you dont need a gmail account. You just go to the second link given below and it generates you valid gmail accounts but without password, it works like a trashmail provider, but with @gmail.com or @googlemail.com at the end. Just click on the button generate till you got a gmail account, because it also generates yahoo, gmx and other providers. You can now recieve emails.
