Yes… think beyond Google. Google’s 15GB free storage is accessible for Gmail, Google Drive and Google Photos. But, yahoo provides 1000GB free storage for each Yahoo Mail account. After creating Yahoo Mail, you can connect Gmail, AOL, Outlook etc and you can use Yahoo as single domain for all email accounts.
Moreover, you can connect Facebook, LinkedIn, Twitter and even Google Drive and Dropbox to access contacts and documents.
Flickr restricts to 1000 free photos upload. So, you can use Yahoo Mail’s 1000GB storage for email and attachments storage. Have a look now.
