Top 5 Free Email Hosting Plans in 2026

Compare five email hosting offers that list a free plan, then decide which provider is worth checking for your own needs in 2026. The key differences are storage, email-app compatibility, encryption and the limits you should verify before signing up.

How we ranked these free-plan email hosts

Only offers that list a free plan qualify here; a free trial alone would not be enough. We rank on listed features rather than lab tests, prioritising practical email access through IMAP, storage, security controls and useful account tools. We also consider limits that can affect a small team, such as user caps, attachment sizes and daily sending allowances.

One important distinction: the named offers below include paid tiers, and a provider’s free-plan flag does not establish that every feature or limit shown for that tier is included for free. Check the provider’s current free-plan terms before moving a domain or relying on a feature. The ranking helps you shortlist providers, not assume that the paid-tier specifications carry over unchanged.

1. Infomaniak Mail Service

Infomaniak is the strongest all-round shortlist choice if you want standard email-app access alongside generous listed capacity. Its offer lists IMAP, POP3 and SMTP, unlimited storage per user, calendar and contacts, two-step verification and a migration tool. That makes it a promising starting point if you are moving existing mail or expect to use both webmail and a mail app. Confirm which of those features apply to the free plan.

• Strengths: IMAP/POP3/SMTP; unlimited storage per user on the listed offer; 2FA; spam and virus filtering; calendar and contacts; migration import; live chat, phone and email support.
• Limits: The listing does not show 24/7 support. It specifies a daily sending limit of 500 emails and a maximum attachment size of 200 MB. Cloud file storage is not included.

It lists support in three channels and a 99.99% uptime guarantee, alongside SPF, DKIM and DMARC. Those are useful details for a custom-domain setup, but check whether they are available on the free tier. Choose Infomaniak first if broad protocol support and storage headroom matter more than having file storage bundled in.

2. Zoho Mail Lite

Zoho Mail Lite is a practical pick if you want familiar client support and round-the-clock help. The listed offer supports IMAP, POP3 and SMTP, Exchange/ActiveSync, desktop and mobile apps, and 2FA. Its 5 GB per-user storage is more defined and modest than Infomaniak’s listed allowance, so check how much room the free plan gives you before migrating a large archive.

• Strengths: IMAP/POP3/SMTP and Exchange/ActiveSync; desktop and mobile apps; 2FA; calendar and contacts; migration import; 24/7 support; 99.99% uptime guarantee.
• Limits: The listed offer has 5 GB per user and shows one mailbox. Attachments are capped at 30 MB. Billing is annual, and the listing says there is no free trial, though it does list a free plan.

Zoho also lists TLS encryption in transit, spam and virus filtering, and an ad-free service. The one-mailbox listing is worth checking against your intended setup, especially if you need several addresses. Pick it if ActiveSync compatibility or around-the-clock support matters to you; verify mailbox and storage allowances on the free plan first.

3. Proton Mail Essentials

Proton is a strong option to investigate if privacy features are your main reason for choosing a free email provider. The listed offer combines end-to-end and zero-access encryption with IMAP support, 2FA, 15 GB per user, calendar and contacts, and open-source apps. It also lists three custom domains, but do not assume that domain allowance is part of the free plan.

• Strengths: End-to-end and zero-access encryption; IMAP/POP3/SMTP; 2FA; open source; 15 GB per user on the listed offer; spam filtering; calendar and contacts; import tool.
• Limits: Exchange/ActiveSync is not listed. The named offer includes one mailbox and caps attachments at 25 MB. The free-plan flag does not confirm that its listed storage or domain allowance is free.

Proton’s listing also includes aliases, a catch-all address, cloud storage and office software. Those extras may help if you want more than email, but check their availability and limits on the free tier. Choose Proton if its encryption approach is your priority and you are comfortable checking which mail clients and account features the free plan supports.

4. Mailfence Entry

Mailfence stands out for a combination of end-to-end encryption and a relatively high listed alias allowance. Its Entry offer lists 10 GB per user, IMAP/POP3/SMTP, 2FA, calendar and contacts, and Exchange/ActiveSync. The offer also supports up to five users, which may suit a small group, though you should confirm whether the free plan has the same team limit.

• Strengths: End-to-end encryption; IMAP/POP3/SMTP and Exchange/ActiveSync; 2FA; 50 aliases; 10 GB per user on the listed offer; calendar and contacts; Belgium data location.
• Limits: The listed offer is capped at five users and two custom domains. It allows 500 emails per day, has a 50 MB attachment limit, and lists email support only.

Mailfence also lists cloud storage, office software, a catch-all address and a migration tool. Those can make it an interesting provider to compare if you want connected work tools, but the free-plan flag alone does not confirm that those extras are included at no cost. Pick it if you want encryption, aliases and ActiveSync; verify the user cap and storage on the free plan.

5. Tuta Mail Essential

Tuta’s listed offer gives privacy-focused users end-to-end and zero-access encryption, 2FA, 50 GB per user, unlimited aliases, and desktop and mobile apps. It also lists three custom domains, a calendar and contacts, and open-source software. However, Tuta is flagged here because its free plan has no IMAP. That can rule it out if you need to connect a conventional third-party email client.

• Strengths: End-to-end and zero-access encryption; 2FA; 50 GB per user on the listed offer; unlimited aliases; desktop and mobile apps; open source; Germany data location.
• Limits: IMAP/POP3/SMTP and Exchange/ActiveSync are not listed. The migration tool is not included, and video meetings are not listed. The offer has a 25 MB attachment limit and does not list 24/7 support.

Tuta may still suit you if you are happy using its own apps and webmail rather than relying on IMAP. Its listed uptime guarantee is 99.95%, and the named offer includes an autoresponder. Before choosing it, check the free plan’s storage and domain terms as well as whether its app-based workflow works with your devices.

How to choose a free email plan

Start with the way you read and send mail. If you need a desktop client or an existing workflow, confirm that the free plan supports IMAP; Tuta’s free plan does not. If you use Exchange/ActiveSync, Zoho and Mailfence list support on their named offers, while Proton and Tuta do not. Check the free-tier terms rather than relying on a paid-tier feature list.

Next, estimate your storage and account needs. A few gigabytes may be enough for a light personal inbox, but an archive or several users can change the calculation. Compare the actual free allowance, mailbox count, attachment cap and any daily sending limit. For custom domains, ask whether the free plan permits your domain and how many addresses or users it covers.

Finally, decide which trade-off you can accept. Privacy-focused encryption may matter more to you than broad client compatibility; another user may value migration tools, support channels or ActiveSync. In 2026, free-plan terms can still change, so check the current limits and any upgrade requirements before pointing a domain’s mail records at a new host.
