Gmail is blocking my emails sent to them

I believe I got blocked for sending too many emails to one address by gmail. I have an application I made and I had email notifications on. It was sending a lot of notifications recently. I have since altered it so I don't send so many, however it seems I was too late. I got blocked for sending too many emails from my site to my gmail account.

Is there a way to appeal this at all?

The reason for being blocked is due to sending too many emails.
