Standard ProtonMail accounts come with 500MB of storage. We will be introducing paid accounts in the future which allow storage limits to be increased.
If you need more space now, it is possible to upgrade to 1GB of storage by donating. To be fair to contributors to our crowdfunding campaign, we have kept the donation amount the same.

Standard ProtonMail accounts provide 500MB of storage space for free, forever. With your donation, your ProtonMail account will have 1GB of storage, forever, for free.
Note, 1GB is the total storage and does not stack with multiple donations.
