   9.2overall

   Google's free email service, with storage shared across Google Drive and Google Photos and paid upgrades through Google One.

   Best formost people who want a free, widely supported address

   Adoption data

   3 billionGoogle said in January 2026 that 3 billion users rely on Gmail.

   Google, Gmail is entering the Gemini era (2026): “Today, 3 billion users rely on Gmail to connect and get things done.”

   Gmail is the email service most people already have, and Google said in January 2026 that 3 billion users rely on it. Every Google account includes 15 GB of free storage, although that allowance also covers Google Drive files and Google Photos, so heavy photo users fill it quickly. Upgrades run through Google One: the US App Store lists 100 GB at $1.99 per month and 200 GB at $2.99, and the Google AI Plus plan with 2 TB adds Gemini in Gmail for $9.99 per month. Google One plans can be shared with up to five other people, which makes the family cost low. Gmail works in almost every mail app and is the address most websites and services expect. The main trade-off is privacy: Gmail is not sold as an end-to-end encrypted service. People who want a provider that cannot read their mail should look at Proton Mail or Tuta instead.

   Strengths

   • +Largest user base of any email service, at 3 billion users per Google
   • +Free tier includes 15 GB, three times the iCloud free allowance
   • +Low-cost storage upgrades from $1.99 per month

   Limitations

   • −Free storage is shared with Drive and Photos backups
   • −Not end-to-end encrypted by default
   • −Google One web prices from our location showed in PLN, so web pricing is quoted from the US App Store

   SummaryGmail is the best choice for most people because its free tier includes 15 GB and Google reports 3 billion users. Privacy-focused users should pick Proton Mail instead.

2. 2

   Outlook.com

   Microsoft's free personal email service, the successor to Hotmail, with ad-free and Copilot features through Microsoft 365.

   8.8overall

   Microsoft's free personal email service, the successor to Hotmail, with ad-free and Copilot features through Microsoft 365.

   Best forWindows users and Microsoft 365 households

   Adoption data

   89.0 millionMicrosoft reported 89.0 million Microsoft 365 Consumer subscribers in fiscal year 2025, the paid plans that add ad-free Outlook.com and extra storage.

   Microsoft, Microsoft 2025 Annual Report (2025): “Microsoft 365 Consumer cloud revenue grew 11% driven by Microsoft 365 Consumer subscriber growth of 8% to 89.0 million”

   Outlook.com is Microsoft's free personal email service and the home of older Hotmail and MSN addresses. The free account works in the Outlook apps for Windows, Mac, iPhone and Android, and the same app can also manage Gmail, Yahoo and iCloud accounts, which makes it a practical hub for people with several addresses. Paid features come through Microsoft 365: the US App Store lists Microsoft 365 Basic at $1.99 per month, Personal at $9.99 and Family at $12.99. Personal and Family add 1 TB of storage per user, the Office apps and Copilot tools for summarizing long threads and drafting replies. Microsoft reported 89.0 million Microsoft 365 Consumer subscribers in fiscal 2025, and the Outlook iPhone app has 9.4 million ratings averaging 4.8. Microsoft does not publish a separate count of free Outlook.com users. As with Gmail, mail is not end-to-end encrypted by default.

   Strengths

   • +Basic upgrade costs $1.99 per month
   • +9.4 million ratings for the Outlook iPhone app, averaging 4.8
   • +Personal and Family plans bundle Word, Excel and PowerPoint

   Limitations

   • −Copilot features need a Personal or Family plan
   • −Not end-to-end encrypted by default
   • −Microsoft no longer publishes a separate Outlook.com user count

   SummaryOutlook.com is the best choice for Windows users because Microsoft 365 Basic adds paid features for $1.99 a month and the higher plans bundle Office. People who do not use Microsoft software get more free storage from Gmail.

3. 3

   Proton Mail

   Swiss-based end-to-end encrypted email service from Proton, with a free plan and paid Mail Plus and Proton Unlimited tiers.

   8.5overall

   Swiss-based end-to-end encrypted email service from Proton, with a free plan and paid Mail Plus and Proton Unlimited tiers.

   Best forpeople who want encrypted email from a large provider

   Adoption data

   100 millionProton says more than 100 million users and organizations use its services, a figure that covers all Proton products, not only Proton Mail.

   Proton, Proton Mail: Get a private, secure, and encrypted email account (2026): “Trusted by over 100 million users and organizations”

   Proton Mail is the largest privacy-first email service in this list, and Proton says more than 100 million users and organizations use its products. Mail is end-to-end encrypted and stored in Switzerland, so Proton cannot read the content of your mailbox. The free plan is modest, with 1 GB and one address. Mail Plus costs $4.99 per month on monthly billing and raises storage to 15 GB, with 10 email addresses, one custom domain, unlimited folders and labels and 10 hide-my-email aliases. Proton Unlimited at $12.99 per month adds 500 GB, 15 extra addresses, three custom domains, an encrypted password manager and encrypted cloud storage. Proton regularly shows first-year discounts on annual plans, so check the renewal price before you commit. The main limits are the small free tier and the fact that full encryption to Gmail or Outlook users requires a password-protected message.

   Strengths

   • +Proton cannot read stored mailbox content
   • +Mail Plus includes 10 hide-my-email aliases
   • +Proton reports more than 100 million users and organizations

   Limitations

   • −Free plan has only 1 GB
   • −Monthly Mail Plus at $4.99 costs more than Gmail or Outlook upgrades
   • −Encryption to people on other providers needs password-protected messages

   SummaryProton Mail is the best choice for privacy-minded people because Mail Plus adds 15 GB, 10 addresses and 10 hide-my-email aliases for $4.99 a month. People who need lots of free storage should look at Yahoo Mail or Gmail.

4. 4

   iCloud Mail

   Apple's email service built into every Apple Account, with Hide My Email and custom domains in iCloud+.

   8.4overall

   Apple's email service built into every Apple Account, with Hide My Email and custom domains in iCloud+.

   Best foriPhone and Mac households

   Adoption data

   2.5 billionApple said in January 2026 that its installed base passed 2.5 billion active devices; Apple does not publish a separate iCloud Mail user count.

   Apple, Apple reports first quarter results (2026): “our installed base now has more than 2.5 billion active devices”

   iCloud Mail comes with every Apple Account and is built into the Mail app on iPhone, iPad and Mac, so Apple users get it without any setup. The free tier is 5 GB, which is shared with device backups and photos and fills fast. iCloud+ is where it becomes good value: Apple's US price list starts at $0.99 per month for 50 GB, then $2.99 for 200 GB and $9.99 for 2 TB, and every iCloud+ plan includes Hide My Email, Custom Email Domain and iCloud Private Relay. Hide My Email generates random addresses that forward to your real inbox, a useful defense against spam and breached sign-up lists. Plans can be shared with up to five family members at no extra cost. Apple said its installed base passed 2.5 billion active devices in January 2026, but it does not report how many people use iCloud Mail. Outside Apple devices, the web client is more limited than Gmail or Outlook.

   Strengths

   • +Cheapest verified paid tier at $0.99 per month
   • +Hide My Email and Custom Email Domain included in every iCloud+ plan
   • +Built into the Mail app on iPhone, iPad and Mac

   Limitations

   • −Free 5 GB is shared with iPhone backups
   • −Best experience is limited to Apple devices
   • −Apple does not publish iCloud Mail user numbers

   SummaryiCloud Mail is the best choice for Apple households because iCloud+ adds Hide My Email and a custom domain from $0.99 a month. Android and Windows users get more from Gmail or Outlook.com.

   Best forpeople who want the most free storage

   Adoption data

   Apple App Store, Yahoo Mail: Your Email & Inbox App - App Store (2026): “4.9M Ratings 4.7”

   Yahoo Mail is still one of the most used free email services, and its iPhone app carries 4.9 million US App Store ratings with an average of 4.7. Its strongest selling point is storage: the free account includes 20 GB, more than Gmail's 15 GB and far more than iCloud's 5 GB, and that space is not shared with photo backups. The app adds AI summaries for long emails, AI Compose with Tone Assist, an Orders Hub that tracks packages, one-tap unsubscribe and bulk delete by sender. It can also pull in Gmail, Outlook and AOL accounts. Paid options are sold as in-app purchases: Yahoo Mail Pro lists at $0.99 per month, Yahoo Mail Plus at $4.99, and storage plans at $1.99 for 100 GB and $9.99 for 1 TB. The paid lineup has several overlapping names, so check which features each plan includes before buying. Yahoo does not publish a current user count.

   Strengths

   • +20 GB free, the largest free allowance in this list
   • +Paid in-app plans start at $0.99 per month
   • +4.9 million US App Store ratings averaging 4.7

   Limitations

   • −Free inbox shows ads
   • −Several overlapping paid plans make the lineup confusing
   • −No current official user count

   SummaryYahoo Mail is the best choice for people who want lots of free space because the free account includes 20 GB. People who care about privacy should choose Proton Mail or Tuta instead.

   7.8overall

   German end-to-end encrypted email and calendar service, formerly Tutanota, with a free plan and low-cost paid tiers.

   Best forprivacy-focused users on a budget

   Adoption data

   10 millionTuta announced in June 2023 that its service had reached 10 million users.

   Tuta, Celebrate with us: Tutanota reaches 10 million users (2023): “Now we have achieved another milestone: 10 million users!”

   Tuta, formerly Tutanota, is a German encrypted email and calendar service that announced 10 million users in June 2023. Mail, contacts and calendars are end-to-end encrypted, and the apps are open source. The free plan is small, with 1 GB, one calendar and three labels, but the paid tiers are cheap for what they include. Revolutionary lists at $3.99 per month or $39.99 per year in the US App Store and adds 20 GB, unlimited calendars and labels, 15 extra email addresses and three custom domains. Legend raises storage to 500 GB for $9.99 per month. Tuta's website shows prices in euros from our location, so the US prices here are the App Store in-app prices. For people who want encryption at a lower price than Proton, Tuta is the strongest alternative.

   Strengths

   • +Revolutionary costs $3.99 per month, less than Proton Mail Plus
   • +3 custom domains on the entry paid plan
   • +Encrypted calendar included

   Limitations

   • −Free plan has only 1 GB and 3 labels
   • −Legend plan at $9.99 per month costs as much as Google AI Plus with 2 TB
   • −Latest published user count is from 2023

   SummaryTuta is the best choice for budget privacy users because Revolutionary includes 20 GB and 3 custom domains for $3.99 a month. People who want more users and reach should pick Proton Mail.

7. 7

   Zoho Mail

   Ad-free email hosting from Zoho with a Forever Free plan for one domain and low-cost Mail Lite plans.

   7.8overall

   Ad-free email hosting from Zoho with a Forever Free plan for one domain and low-cost Mail Lite plans.

   Best forpeople who own a domain and want ad-free mail

   Adoption data

   16 millionZoho said in February 2022 that Zoho Workplace, the suite that includes Zoho Mail, served more than 16 million users.

   Zoho, Zoho Workplace Touts Consecutive Years of Exceptional Growth and Record Migrations from Competitor Suites (2022): “now serves more than 16 million users globally”

   Zoho Mail is mainly sold as domain email, which makes it a good fit for people who own a personal or family domain and want an ad-free inbox. The Forever Free plan hosts one domain for up to five users with 5 GB each, although it leaves out IMAP, POP and ActiveSync, so you are limited to Zoho's web and mobile apps. Paid plans are cheap: Mail Lite costs US$1 per user per month for 5 GB or US$1.25 for 10 GB on annual billing, and Mail Premium costs US$4. Zoho states that it will never serve ads or sell data to third parties, a clear difference from the large free providers. Zoho said its Workplace suite, which includes Mail, served more than 16 million users in 2022. The downside is a setup process aimed at domain owners, so it is less suited to someone who just wants a quick free address.

   Strengths

   • +Ad-free, including on the free plan
   • +Paid plans start at US$1 per month
   • +Free plan covers up to 5 people on one domain

   Limitations

   • −Free plan excludes IMAP, POP and ActiveSync
   • −Built for domain email, so less suited to a simple personal address
   • −User count covers the whole Workplace suite and dates from 2022

   SummaryZoho Mail is the best choice for domain owners because Mail Lite costs US$1 per user per month with no ads. People without a domain will find Gmail or Outlook.com easier to start with.

   Apple App Store, Fastmail - Email & Calendar App - App Store (2026): “611 Ratings 3.9”

   Fastmail is a paid-only email service, which is its main appeal: there are no ads and the business model is the subscription. Every plan includes 60 GB per person, split into 50 GB for mail, calendar and contacts and 10 GB for files, along with custom domains, extra addresses, Masked Email for hiding your real address, scheduled send, snooze and offline support in the apps.

The US App Store lists the monthly Individual plan at $6.49; the website showed prices only in local currency from our location. Duo covers two people and Family covers up to six. A free trial of up to 30 days lets you test it before paying. Fastmail does not publish user numbers, and its iPhone app has 611 US App Store ratings averaging 3.9, so it scores low on adoption.

   Strengths

   • +No ads and no free tier to subsidize
   • +60 GB per person, the most generous paid entry storage here
   • +Masked Email included on every plan

   Limitations

   • −No free plan, only a trial of up to 30 days
   • −Most expensive entry price in this list at $6.49 per month
   • −No published user count and a small US App Store rating base

   SummaryFastmail is the best choice for people who want an ad-free paid inbox because every plan includes 60 GB per person, custom domains and Masked Email. Budget buyers get similar privacy tools for less with iCloud+ or Tuta.

AOL Mail Plus removes paid ads from AOL webmail and lists at $1.99 per month or $19.99 per year in the US App Store. AOL also sells security, identity protection and tech support bundles, which can make the upgrade path confusing.
