If you wish to modify the frequency of the notifications that you receive by e-mail, access your account settings by clicking on your "Name" and then on "Settings".
Once you have entered the configuration panel of your account, in the last module you will find the option to choose the frequency of your notifications.
New images and alerts
New products and promotions
Choose how often you want to receive emails:
Daily (once a day, if there are new images or abnormalities).
Weekly (once a week).
Monthly (once a month).
Never (I swear you will not receive any more notifications).
