Exploring Different Email Providers: Which Is Right for You in 2025?

Exploring Different Email Providers: Which Is Right for You in 2025?

In many ways, your email inbox provides a playing ground for businesses of all sizes and types. 

If you can build a list of engaged subscribers and deliver relevant messages, a small business has about the same chance of reaching someone with email as a Fortune 500 company. 

But, the chances of deliverability all come down to the email provider you choose. 

According to Validity’s research, the majority of marketers feel that email deliverability is getting harder, and a major reason could be your email provider.

So, which email provider should you choose? There are over 300 different types of email providers available, and you might just need a few (one, in most cases). 

If you chose poorly, you might face:

  • Annoying outages
  • Risks to your data
  • Missing features that slow you down

To help you avoid these issues, we have created this guide. We have selected the top 10 free different email providers for 2025 that would fit almost all business types, usage, and goals. By the end of it, you’ll know which service fits the best. 

What are the different email providers? The best 10 free 

Many companies have a free email service available, but some are better than others. 

For instance, Gmail offers Gemini AI to assist in drafting emails; Outlook seamlessly integrates with Word, Excel, and PowerPoint via Microsoft 365 or Mailbrid, which supports integration with various email providers like Gmail and Outlook. 

Navigating through similar email providers on your own is challenging and time-consuming. We’ll help you pick the best ones and tell you what makes them special. 

Here’s a list of different email providers that you can use for free:

  1. Gmail → best overall free email account
  2. Outlook → best for Microsoft 365 users
  3. Yahoo → great email storage
  4. iCloud → best of Apple users
  5. Shortwave → AI-powered email management platform 
  6. Mailbird → best for managing multiple email accounts
  7. Neo → best for custom domain
  8. Zoho Mail → great for Business Users
  9. ProtonMail → best for security 
  10. AOL Mail → best for Long-Term Storage

Learn more about these top mail service providers below!

Is Gmail still the top choice?

What do we like? What we don’t like? 
  • 15 GB storage shared across Google Workspace.
  • Advanced spam filter capabilities.
  • Highly secured and sends immediate alerts in case of suspicious activity.
  • Labels, filters, templates and stars
  • Custom domain only on paid plans. 
  • Free storage is limited 

Ask any ten marketers what email providers they use for email marketing, and odds are that eight of them would say Gmail. As of 2024, Gmail holds a substantial 27.76% share of the Global email market (after Apple Mail), and is estimated to send 376.4 billion emails daily by 2025. 

The platform has become a preferred email provider for over 60% of small and medium-sized businesses, thanks to its cost-effectiveness and integrations with Google Workspace. 

Gmail’s growth is thanks to its strong features. Robust spam filtering, Smart Compose (writing emails through Gemini AI), and the platform’s user-friendly design are largely responsible for how many people use Gmail. Businesses can use smart labels, stars, and priority inboxes to help them categorize emails efficiently,  arranging messaging according to emergency.

Gmail offers two prominent security features: two-factor authentication and end-to-end encryption. Both have significantly reduced phishing attacks and data breaches. In fact, Gmail blocks 15 billion spam emails and stops 100 million phishing emails daily.

Who should use Gmail?

How does Outlook compare?

What do we like? What we don’t like? 
  • Simple to use and perfect for beginners.
  • Store up to 15 gigabytes (GB) of mail and five GB of OneDrive storage for storing important documents, images or videos. 
  • Malware detection and email encryption. 
  • Color coding and categories (for organizing emails)
  • Not efficient in filtering junk emails. 
  • Might feel buggy sometime
  • Search feature return irrelevant search 
  • Email limitations 

Outlook currently holds about 4.38% market share for email platforms, with over 400 million active users worldwide as of late 2024. Outlook is an excellent platform for users receiving multiple communications per day. 

Many businesses prefer to use Outlook because of its built-in calendar and contact features that allow communication to be more efficient. Unlike Gmail, which uses labels to separate emails, Outlook allows users to create a designated folder for their emails. 

list of different email providers is nothing without Outlook

Outlook’s AI, Copilot, can summarize lengthy email threads, suggest responses, and draft emails with customizable length and tone. Outlook and Gmail both integrate with Zapier, which means you can automate them and connect with a thousand other apps. You can seamlessly use Outlook for email marketing. However, it has a limitation of 300 emails daily. 

Outlook allows you to create mail rules, enabling new messages to be automatically moved to a designated folder, categorized, flagged, or forwarded based on specified conditions.

Who should use Outlook? 

If you’ve already invested your money into Microsoft 365, then Outlook email can provide a well-integrated option.

Is Yahoo still relevant? 

What do we like? What we don’t like? 
  • Tons of email storage.
  • Lets you make free disposable emails.
  • Can access Yahoo calendar from the email dashboard.
  • Easy and intuitive to use and customize
  • Excessive ads.
  • Limited features compared to other different email service providers.

The only reason someone will choose Yahoo over Gmail and Outlook is because of its free 1TB storage space. This is way more space than any email service provider and can conveniently store years of emails sent and received, as well as photos and files. The platform’s intuitive interface makes it easier to navigate through documents, photos, and videos super fast. 

Yahoo Mail is probably the best email provider when it comes to alternate identities and or aliases. You can create up to 3 free disposal addresses linked to your inbox without revealing your actual addresses. This is extremely effective in avoiding spam messages since your regular inbox won’t be affected and you can always delete your disposable address.

Even though Yahoo can handle the basics of sending emails, it has a unique record of having the largest data breach. In two separate attacks in 2013 and 2014, hackers accessed data from 3 billion Yahoo accounts. This includes names, email addresses, telephone numbers, security questions and answers, and more. The attackers were able to use fake web cookies to log into any account. 

With time, Yahoo Mail has prioritized security by:

  • Removing junk or spam emails
  • Sending phishing alerts
  • Mail Forwarding alerts ( Yahoo Mail Plus only).
  • Enabling two-factor authentication 

Who should use Yahoo? 

Yahoo Mail is ideal for businesses and individuals needing substantial email storage, especially those dealing with large attachments. If you want more advanced mail features like inbox organization, integration, or automation then other email providers could be a great option.

What makes iCloud Mail a good option? 

What do we like? What we don’t like? 
  • 5 GB of free storage for emails. 
  • IMAP support, large file attachment support (up to 5 GB via Mail Drop) and two-click method to unsubscribe. 
  • Seamlessly integrate with Apple devices and productivity apps. 
  • Not as advanced features as other providers. 
  • Limited space (only 5GB, compared to 1 TB in Yahoo)

iCloud by Apple is one of the most popular free email providers after Gmail and has over 850 million users.

The biggest assumption users have about iCloud is that it’s only accessible on Apple, but that’s not true. Apple Mail works only on Apple devices, while iCloud works on any device, even non-Apple ones. It’s available as a web app that can be accessed from any web browser, so it is quite versatile for those who need to check inboxes on Apple and non-apple devices. 

The ability to access your data in real-time is an added benefit, the synchronization between devices and other Apple productivity apps such as calendar, notes, and reminders. This integration allows you to create events effortlessly, set reminders, and jot down notes directly from your emails.

 The email portion on iCloud isn’t super advanced and probably won’t serve you well if you want a lot of options. You can simply organize your emails with folders, search and filter. You can also set up rules to filter email, automatically forward email, and more.

Unlike other email providers, you don’t have to go through the tedious process of adding your name and choosing a password. All of this works well with your existing Apple Account or a new free iCloud account.

Who should choose iCloud? 

Most Apple users stick with iCloud mail because of its solid email functionality, Apple-like interface, and seamless integration with the Apple ecosystem. Even though iCloud runs on non-apple devices, general users can look for better options.

How does Shortwave stand out? 

What do we like? What we don’t like? 
  • AI-powered email management 
  • Summarises emails quickly
  • Supports multiple Gmail accounts
  • Intuitive interface (multi-panel set-up)
  • Free version restricts email access to 90 days.
  •  A third-party email app, not a provider.

Before we begin, Shortwave is a third-party email app, not a provider. For it to work, you’ll have to link it to your existing Gmail inbox–they let you access those messages from a superior interface. 

Shortwave ensures you’re not drowning in emails. All your emails are already sorted in your inbox. It neatly tucks away emails like purchase receipts and newsletters in their bundle, so you can easily filter through emails.

You can easily create new bundles by simply dragging and dropping emails onto each other. It’s a pretty neat interface and completely customizable. 

Compared to different types of email providers, Shortwave’s multi-panel setup is far more personalized. On the left menu, for example, you can add shortcuts to your most frequently visited sections or search results–like any specific keywords or category.

Similarly, on the right panel, you’ll find Shortwave’s main inbox with pro tools you can hide or reveal to your preferences. There’s a calendar tab that checks for upcoming appointments and an activity tab for tracking which recipient has opened the email. 

Who should choose Shortwave?

Shortwave is an excellent option for Gmail users who deal with a lot of emails on a daily basis. It helps professionals distinguish the important emails from the not-so-important ones.

Is Mailbird worth trying? 

What do we like? What we don’t like? 
  • Easily manage several email accounts from a unified inbox.
  • Email templates and (soon) AI-powered replies.
  • Seamless integration of many popular apps.
  • Useful inbox management features.
  • Only available for Windows, limiting cross-platform accessibility.
  • May cause missed emails due to syncing issues.
  • Limited functionality compared to other providers. 

Having excelled on Windows for years, Mailbird is a sleek, modern email client that integrates with various apps and services, providing an ultimate solution for managing communications, tasks, and more. 

Mailbird stands out with its unified inbox feature, which allows you to control all your contacts and emails in one place. That means you can add multiple mail accounts and access them from Mailbird.  It supports POP3, IMAP, and SMTP, which means it can work with virtually any email service.

Mailbird offers email templates for faster email composition. With their help, you can quickly insert pre-written text for common responses. When it comes to inbox management, Mailbird provides several useful tools to keep your inbox organized, like:

  • With message snoozing, you can temporarily remove non-urgent emails from your inbox.
  • Create auto-rules to automate routine and repetitive tasks, such as emails moving into separate folders based on the sender or content, marking emails as read, or archiving unimportant emails. 

Another key feature where Mailbird shines is app interaction. You can integrate email with a wide variety of apps and services. This includes Dropbox, Google Workspace, Facebook, Twitter, Linkedin and more. You can also access calendars, to-do lists, and more from your account without switching tabs.

Who should choose Mailbird? 

Mailbird works well for individuals and businesses that manage multiple email accounts from various providers (e.g., Gmail, Outlook, Yahoo) in a single, unified inbox. You can easily jiggle between your personal and professional emails.

Like Gmail and Outlook, Neo has also launched its AI tool called Smart Write. You just have to explain what email you need, the tone you want to use, and your preferred message length. Smart Write will write an entire message for you that you can edit or send right away.

Unfortunately, Neo doesn’t offer a free plan, but you can opt for a free 15-day trial before you choose from one of two available plans. However, its basic plan you can get:

  • Add email rules on how specific emails should be treated–starred, marked as unread, or redirected to appropriate folders. 
  • Set up an auto-reply for all incoming emails when you’re away. 
  • Share your calendar and make appointments right from your inbox.
  • One-click import of existing emails and contacts.

Neo’s secure credentials are solid and offer end-to-end encryption, two-factor authentication, and anti-spam functionality. It is also hosted by Amazon Web Services, which should give users a little extra peace of mind.

Who should choose Neo? 

Neo is geared towards entrepreneurs, startups, and small businesses who are seeking professional email addresses and flexible cloud storage and exploring AI tools like Smart Write for creating AI-generated emails.

Is Zoho Mail good for businesses? 

What do we like? What we don’t like?
  • Connecting to other Zoho apps is easy.
  • The design is clean and minimal.
  • Email hosting for one domain for up to 5 users for free. 
  • Extensive integrations with mail-suite apps, Zoho apps and Zapier. 
  • IMAP, POP, and Active Sync aren’t included in the free plan.
  • Limited functionality in free plan. 

Zoho Mail is a professional email service provider of Zoho’s cloud-based office suite. Unlike Gmail and Yahoo, which charge users for custom domains, Zoho offers email hosting for one domain for up to 5 users for free.

Its Streams feature makes it easy to create groups where you and your team members can easily collaborate with shared messages and attachments. It works a bit like a private social media site. Zoho mail also provides you with an integrated Calendar, Notes, To-do, and Bookmarks right within your inbox–helping users be productive with everything you need in one window.

Zoho Mail keeps your inbox clean while providing a smooth user experience with the following:

  • Set up filters or rules to automatically organize your emails. 
  • Set an Out of Office response to let contacts know you’re unavailable.
  • Add email signatures with your company’s logo and link to your website.

The platform protects all its users by offering email encryption and two-factor authentication per default across all pricing plans. 

Unfortunately, free accounts are limited to 5GB of storage and 25 MB attachments, assuming you’re not a super heavy user. 

Who should choose Zoho Mail?

 Zoho Mail is ideal for small to medium-sized businesses seeking a professional email address (for free) that combines robust security features with collaboration tools, all at an affordable price.

Why do people choose ProtonMail? 

What do we like? What we don’t like?
  • Highest level of security 
  • Choose when an email will expire.
  • Safe from spam and phishing
  • Send encrypted emails to anyone, even if they don’t use ProtonMail. 
  • Limited to 1 GB of storage.
  • Free account limited to 150 messages per day.
  • Supports only three folders and labels.

ProtonMail is primarily used for secure and private communication. It is especially popular among individuals and businesses that require a high level of security. 

Unlike popular email providers, such as Gmail, Outlook, and Yahoo, which scan the content of your email, ProtonMail is end-to-end encrypted along with Zero access encryption, which ensures that you can see your emails. Not even Proton can view the content of your emails and attachments.

Recipients who receive encrypted emails are assigned a password to open them. They can reply through an encrypted channel via the same message and don’t need a Proton account. 

ProtonMail is also quite easy to use and optimized for productivity. Besides providing the highest standard of security, ProtonMail provides inbox organization with labels, folders, and filters. 

A major drawback for ProtonMail is its storage space. Free users only get 1 GB of free storage, which is quite low compared to other email platforms. 

Who should choose ProtonMail?

ProtonMail would work well for individuals and businesses that prioritize security above all. If you want to keep your conversations private, then you should definitely go for ProtonMail.

Is AOLMail still a thing? 

What do we like? What we don’t like?
  • 1TB of storage space
  • A calendar and to-do list accessible from the inbox 
  • Easy-to-use platform
  • Limited functionality.  
  • Lots of ads. 

AOLMail is one of the earliest and most well-known free email service providers. Even though its popularity has decreased over the years, it’s still one of the best email providers in terms of storage. 

Unlike other email providers whose free storage limit is stuck in gigabytes, AOL offers 1TB of storage for free. This makes it a great option for long-term message storage and combining multiple email accounts. 

Like most email providers, AOL provides essential email features such as spam filtering, inbox organization, and the ability to create automated rules. Similar to Yahoo email, AOL provides an in-built GIF gallery for seamless communication.

Your AOL account also comes with a calendar and to-do list that can be accessed from your inbox. However, features like chat rooms require a paid version. 

Who should use AOLMail? 

AOLMail is suitable for users who prioritize storage space over advanced email functions. It’s a straightforward and easy-to-use interface, making it accessible even for those with minimal technical skills.

How do you choose the right email provider? 

Now that you have an amazing list of 10 email service providers, it’s time to understand how to choose the best one for your business. 

The right service provider should meet your unique business’s needs and make your marketing efforts more successful. You’ll want to choose the most appropriate email service provider according to your business’s size and functions, minimize the time it takes to set up campaigns, and streamline daily operations. 

Let’s look at what you need to look out for as you shop around:

Features

When doing a side-by-side analysis of email providers, think of the features that line up with your goals and are within your budget.

Below are some key features that you can prioritize:

  • Deliverability: Look for ESPs with a strong track record of high deliverability rates and good sender reputation.

For instance, ProtonMail has a high deliverability rate of 74.98% (average spam rate-12.29%); on the other hand, Outlook has a deliverability rate of just 46.54% (average spam rate-31.47%)

  • Email list management: Your email provider should provide tools for managing your email list, such as segmentation, contact management, and labeling. 

For instance, Zoho mail allows you to create mailing lists to group contacts together based on various criteria. 

  • Email Templates and automation: Look for a platform that offers customizable email templates and automation features to help you create engaging emails in seconds. 

For instance, Gmail offers Gemini AI, which lets you write emails through AI. You just have to provide a prompt on what the email is all about, and the AI will do the magic.

  • Security and Compliance: Ensure your service provider follows best practices for data security and complies with email marketing regulations such as GDPR and the CAN-SPAM Act. Also, look for data encryption, two-factor authentication, and alias addresses for better security. 

For instance, Outlook, AOL, Gmail, and Zoho Mail are all GDPR and CAN-SPAM Act compliant. 

Ease of use 

Let’s face it. Email marketing, especially automation, is quite a complicated affair. That’s why you need an email provider that’s easy to use. You don’t want to be dependent on your technical team (if you have one) or look for solutions online to learn how to use the platform. 

Here are a few questions you can ask for:

  • Are the specified features easy to use?
  • Is the platform optimized for mobile and responsive design?
  • Is the interface well-organized and intuitive?
  • How long is the learning curve?

Integrations 

When it comes to marketing, email marketers use an average of 5 apps to power their marketing efforts. This includes everything from analytics to automation and everything in between. 

Data integration involves linking various systems, including web analytics, CRM platforms, content management systems, and eCommerce platforms, into a unified system. It is crucial to have top integrations available so you can use the data for segmentation, personalization, and scaling your outreach efforts. 

For instance, ProtonMail, ZohoMail, Gmail, Yahoo Mail, and Outlook offer integration capabilities with various third-party applications through IMAP/SMTP support.

Scalability 

Assuming you’re looking for a free email service provider, you probably have a mailing list of less than 2000 subscribers. The question is, will your ESP have the capability to send emails when your mailing list explodes to over 20,000 or 200,000 subscribers? 

Your service provider should be able to meet your needs both now and in the future. Pay attention to service providers that are evolving their services to fit better people’s needs versus those that are staying the same.

Which ones are the best for cold outreach? 

If possible, when choosing your email provider for cold emailing, it’s vital that you don’t go with a free option like a free personal Outlook or Gmail account. 

The reason to avoid them is that if there’s any issues, you’ll quickly get blocked from using them, as high-volume outreach is against the terms of these free accounts. 

However, if you still want to go a free service provider then the following options stand out based on their features and overall effectiveness:

Email provider Gmail Outlook  iCloud Mail  Zoho Mail
Inbox size 15 GB 1 GB 5 GB 5 GB
Max attachment size 25 MB 20 MB 20 MB 1 GB
Messages per day 500 300 1,000 1,000
Cloud storage 15 GB 5 GB 5 GB 5 GB
2FA Yes Yes Yes Yes
POP3/IMAP/SMTP Yes Yes Yes Yes

Connect your email to your outreach automation software 

Most business professionals send a huge amount of emails every day for outreach, especially those who work in sales, marketing, and BD, so it’s crucial for businesses to maintain strong deliverability. 

This will not only ensure that your email reaches their designated recipients but also your business IP maintains a strong reputation, preventing it from getting blacklisted. 

To ensure that everything runs smoothly, from a security and deliverability standpoint, it’s advisable to use a leading outreach automation tool like Reply.io.
