Due to this problem, Gmail has received low rankings in security assessments.

15 GB storage (Google Drive) Data protection concerns: forwarding of user data, inadequate privacy regulations
Direct connection to other Google services  
Good spam filter

Most alternatives to Gmail are characterized by high levels of data security. This is because Google’s general terms and conditions allow the provider to read email content. But Gmail isn’t the only email service with questionable data protection.

If you’re looking for a free alternative that guarantees better data protection, then switching to one of the providers discussed in this article could be a logical move. Some of the free versions offer fewer functions – for organizing appointments, for example – and a relatively small amount of storage, but this can usually be solved with a paid upgrade.
