The best email hosting providers of 2022 in full(opens in new tab)
If you are a small business with a small headcount and don’t want to spend hundreds of dollars on email accounts, then consider this. From EIG-owned Bluehost (opens in new tab) comes an exclusive business email package for TechRadar readers where you get unlimited email accounts and email storage when you sign up to the Plus and Choice Plus plans. Is it truly unlimited though?
Bluehost says that they do not enforce any official limitations. Furthermore, they add “while email account creation is unlimited, these rely on the file storage available on the account. Therefore customers need to be operating within the Terms of Service to ensure resources are available to fully enable email functionality. Customers operating within the Terms of Service have yet to come up against technical boundaries for email, domains, or websites”.
What’s the catch then? For a start, while you get POP3 and IMAP4 plus 24/7 support, this is more of a barebone solution. You get to choose between three webmail applications (the equivalent of Outlook.com or Gmail.com); Horde, Roundcube or Squirrelmail.
You can of course configure an email client like Mail for Windows 10 or Mozilla Thunderbird to read your emails offline. Creating a new email address is a doddle thanks to an easy user interface.

Like Bluehost, Hostinger (opens in new tab) also offers email hosting with a difference, delivering the easy-to-use Titan interface to make it easy to use, send, and search your emails. This also includes a calendar app to make it easy to organize and set schedules, and the whole interface is mobile friendly.
Additionally, there is also video integration available for conferencing, which makes it especially useful for business use.
There are two main plans available, both of which come with up to 50 email aliases, antivirus checking, and multi-device support.
The Business email hosting plan offers 10GB of storage, 2 mail filters for just $0.99 a month per mailbox. The Enterprise email hosting plan increases these limits to 30GB of storage and unlimited mail filters, for just $2.49 a month.
All in all, the Hostinger email hosting plan offers simplicity yet usability for a very affordable price. Hostinger offers both email and web hosting on a single dashboard, which includes an advanced search function through Titan, and overall, has great email security.

Dreamhost (opens in new tab) offers standalone email hosting among the range of different packages that this established web hosting services provider offers.
Dreamhost's email hosting offers 25GB of storage by default, with the ability to sync emails between desktop and mobile devices. Additionally, there's an ad-free webmail software platform included.
Another key feature is a smart anti-spam filter, which ensures the filtering of spam messages, but also viruses, malware, and phishing attacks. The filter is adaptive to emerging threats, ensuring that you remain protected.
There are a couple of key advantages in having your own hosted email account. The first is that it remains connected to your company domain name, which looks far more professional than a free email account.
Additionally, it also means you have complete control over your own data, and that your emails won't be automatically scanned to provide advertising at you, something free email providers do all too commonly.
Pricing is relatively inexpensive, and depends on whether you wish to pay on a monthly basis or commit to annual payments. Monthly plans cost just $1.99 a month, while a yearly commitment reduces this to the equivalent of $1.67 a month.

Zoho (opens in new tab) Mail is a hosted email service with a bundled online office suite, and a stack of other extras. Several of the newest features Zoho Mail introduced, are: Offline Mode, undo mail, recall mail, huge attachments (up to 250MB), audio/video calls, and a few others. Zoho Mail also has an IMAP client, so you can configure, sync, and manage your other email accounts via IMAP.
A free plan gives you five mailboxes with up to 5GB per user, a 25MB attachment limit and webmail access. A referral scheme could get you support for a further 25 mailboxes (at the time of writing the referral program wasn't available due to remodeling).
If that's too basic, the Standard plan gets you IMAP and POP support, 500MB attachments and 30GB of storage, 5GB file storage space, and support for working with multiple domains. That's more capable than some of the premium competition, and includes the same productivity tools as the free suite, yet still only costs $3 per user per month, billed annually.
Zoho made the list of the best email hosting providers because its Professional plan gets you 100GB of storage (per user), 1GB attachments, support for Active Directory groups, and more. It's yours for $6 per user per month (billed annually), not bad at all for the storage space and features you're getting. Also, Lite plan is available with less features, but it's only $1 per user per month, billed annually.

Best email hosting FAQs
What is email hosting?
Email hosting is a service in which a hosting provider rents out email servers to its users. The basics of email hosting isn’t complicated. There are free versions of email hosting available but the best email hosting providers for power, flexibility and professionalism are available for a fee.
While it's usually included with a web hosting package, email hosting is a separate service that lets you set up a custom email address and use it to send and receive emails. What adds to the professionalism is that the email domain name you use will match your website.
Free email services using a public domain such as Gmail or Yahoo are more suitable for individual and personal use. Shared hosting email services are large mailboxes that are hosted on a server. Those on a shared hosting email service share IP addresses as they are hosted on the same server.
Cloud email services are suitable for small companies and SMEs. These mailboxes are hosted externally utilizing a cloud service provider, such as Gsuite by Gmail and Microsoft Exchange Emails by Microsoft.
Enterprise email solutions are suitable for SMEs and large corporations that host several mailboxes. These are located on dedicated servers on the premises or on a cloud based server that can scale horizontally.
How to choose the best email hosting providers for you?
Email has been the main way to communicate on the internet for a very long time so it's only right that you sign up to the best email hosting provider to deliver quality email hosting services.
One of the very first things you should be looking for in an email hosting provider is whether it's safe and secure. As some emails sent across businesses contain highly sensitive data, might want to focus on a hosting service that can protect the content of your email against potential cyber attacks.
You also need to decide how you’re going to host your email, which could be via third-party email hosting, shared web and email hosting, or even self-hosted email.
It's also important to pick an email hosting service that offers flexibility and 24/7 customer support. The ability to change your email settings to fit your needs is something that the email hosting provider that you choose should have.
Lastly, storage and uptime should be on your mind when picking the right email hosting service for you. Look for an email hosting service that gives you the option to have all your data in one place, and an option to move your old messages into the archive automatically. You should also choose an email host that will guarantee you at least 99.9% of uptime.
How we test the best email hosting providers
Focusing on the main features we pointed out above, we test email hosting providers by signing up to each service and testing out the flexibility, availability, support and security aspects of the product.
A good quality email hosting provider would be able to meet all your needs in these areas and would offer some sort of 24/7 customer support should you need extra assistance when things go wrong or you have a query about the service.
We also test some of the bonus features that email hosting services provide to improve your business performance. We also test the sending limits each provider sets in order to see the number of files and attachments you're permitted to send. Some email hosting providers come with file-sharing tools if you want to send much larger documents.
Things to look for in your next email hosting
If you want to host email accounts together with your website, then you should look at these email features before signup.
Most hosting companies will offer the ability to host your own email (something like email@yourdomain. com). Your package will include a number of email accounts – usually between 1-10 for basic hosting.
You’ll be given access to your own email control panel to set up your accounts. Using email requires two things: an email server and an email application, this could be an email client such as Outlook, or alternatively access to Webmail like Gmail or Yahoo.
The email server is a piece of software that runs on the server and is constantly connected to the internet. It receives and processes any mail sent to it and sends out any mail you send.
The email client is an app that runs on your PC, phone or tablet and enables you to send, receive and organise your emails, e.g. Microsoft Outlook. The client checks the mail server for messages and downloads them for viewing. It is a control panel for reading and writing messages.
The good news is that most email clients can connect with most email servers, you can even connect multiple email servers to work with multiple email accounts.
So your work and personal emails can be accessed from the same email client. The more popular email clients such as Outlook give you more features (calendars, tasks etc.) than using webmail.
Webmail is a web-based email interface that can be accessed in a web browser is often faster and more convenient because it accesses the stored data more directly without the user having to download software locally.
Emails can be checked from any device with access to the internet. Email protocols are a set of rules that help the client to send the information to or from the mail server. Two of the most common email protocols are POP and IMAP:
1. POP (Post office protocol) Applications like Outlook will use POP to download emails from the server to your computer and then delete them on the server.
2. IMAP (Internet message access protocol) IMAP is more advanced than POP, with IMAP, emails are stored in the mail server and can be accessed from any clients anywhere if they all use IMAP.
Mail data is kept on the server as well as your computer, until you delete the mail. When comparing hosting packages, be sure to choose one with full IMAP support.
Exchange Exchange is the gold standard email protocol – the most expensive option of the three, but for good reason. It’s a Microsoft protocol that gives you the power to sync tasks like IMAP does, but with the added ability to share contacts and calendars among employees.
If you can afford to pay the extra cost (around $9.99 per month per mailbox), you will reap the benefits of its advanced functionality and tools which can be used even when you are on the move.
What is DKIM?
By: Peter Goldstein, chief technology officer and co-founder, Valimail
DomainKeys Identified Mail, also known as DKIM, is an email authentication protocol that describes how organizations can use public-key cryptography to securely sign messages and enable recipients to confirm that messages originated from intended senders and were not altered in transit.
Public-key cryptography is based on an encryption technique that involves a pair of keys—one is kept private by the owner of the keys and the other is public for all to see. Within public-key cryptography, it’s common for the owner of the private key to digitally sign a message and then anyone can verify that signature using the signer’s public key. DKIM relies on this signature technique.
How DKIM works
At a basic level, DKIM works as follows:
Advantages of DKIM
DKIM’s primary advantage over Sender Policy Framework (SPF)—its predecessor in the email authentication space—is that it is designed to preserve authentication through forwarding.
SPF is IP–based, so any message that routes through an intermediary is likely to fail SPF checks since the originating domain probably didn’t include (and likely shouldn’t have included) the intermediary IP address in its SPF record.
Because of DKIM’s cryptographic signatures, recipients can also be assured that forwarders did not alter the message in transit. This prevents malicious behavior from forwarders who may not be known to either the initial sending system or the receiving system.
DKIM alone is not enough
DKIM with Domain-based Message Authentication, Reporting and Conformance (DMARC) will achieve a far greater level of protection. That’s because DMARC requires alignment, meaning what is validated by DKIM must also match what appears in the “From” field of the email. Together with DMARC, DKIM is an important element of a fully-fledged anti-spam and anti-phishing solution.
