In their own words

Proton Mail

Proton Mail is an encrypted email service available on the web, Windows, macOS, Linux, iOS, and Android. Its free plan lists 1 GB of storage and one email address, although its FAQ says storage starts at 500 MB; the free tier is described as having the same security level as paid plans. The service uses end-to-end and zero-access encryption, with open-source apps and independent audits. It blocks email trackers and includes phishing and spam protection, password-protected messages, and link confirmation. Users can schedule, undo, or snooze emails and organize messages with folders, labels, and categories. Easy Switch imports email, calendars, and contacts from other providers. Paid plans support external email clients through IMAP and SMTP using Proton Mail Bridge. Mail Plus lists 15 GB of storage, 10 extra email addresses, and one custom domain. Paid subscriptions include a 30-day money-back guarantee, and the desktop app has a 14-day free trial. Paid plans display monthly billing; the listed starting price is 3.99 /user/mo.

Yahoo Mail

Yahoo Mail is an email service for web, Android, and iOS, with a free Standard plan and a paid Yahoo Mail Plus plan. Standard includes 20 GB of storage, inbox organization tools, and up to three temporary email addresses. Yahoo Mail Plus costs $5 per month and includes 200 GB, an ad-free inbox, and up to 500 temporary addresses. Plus also provides live, around-the-clock help for general Yahoo account questions, including billing, password resets, and account recovery. A 14-day free trial is available; cancel before it ends to avoid the recurring subscription fee. Both plans offer web and mobile access, and users can add Gmail, Outlook, or AOL accounts in one place. Inbox tools include one-tap unsubscribe, customizable notifications, and email search organization. Plus subscriptions renew automatically unless canceled before the renewal date. Yahoo Mail supports email aliases, and the service is made by Yahoo, headquartered in New York, United States.
