Frequently Asked Questions
What is the best free email app?
Gmail is a strong free choice: it includes 15 GB of storage shared with Google Drive and Google Photos, automatic categories and spam protection. Outlook.com is the closest free alternative, with 15 GB of mailbox storage and a built-in calendar and to-do list.
Is there a better mail app than Gmail?
It depends on what you need. For privacy, Proton Mail offers end-to-end and zero-access encryption. For team collaboration, Spark lets colleagues write emails together and comment privately on threads. For Apple users, Apple Mail is built in and offers Mail Privacy Protection.
Is Gmail still free?
Yes. Every Google account comes with up to 15 GB of free storage shared across Gmail, Drive and Photos. Google One plans add more storage, and Google Workspace plans are available for businesses.
Is Gmail safer than Hotmail?
Hotmail is now Outlook.com, and old Hotmail addresses still work in Outlook. Both include spam filtering. Gmail’s site lists phishing warnings and Confidential Mode, while Microsoft keeps its advanced security features for Microsoft 365 plans. Either is far safer with a strong, unique password and two-step sign-in turned on.
