synching was a pain. if their server goes down (and it did multiple times) your emails will not flood in. If your email is on another type of server you can log in online and access your inbox but then you will need to wait for it to sync once it is back up

Owner

I filed three support tickets, made four phone calls, sent three email and never got a response other than a list of articles to read and "Check your settings."

Independent Visual Artist

Communication is secure, spam is filtered effectively, and the interface remains intuitive even for complex tasks.

Sales Manager

My favorite thing about Zoho Mail is that it offered a free business email that I could connect to my own domain.

Band manager

I really love having discovered ZOHO, I use it to manage a professional email extension (@companyname.com...) and the features like its lightness and especially the multiple options for sending out scheduled emails on a specific, time, day, date and repeatedly as you wish are my favorite options.

Self-employed

I had some minor issues when setting up and initially configuring my domain, but after changing/customizing some settings, everything works as expected now.

I have used Zoho Mail for business emails, using the free plan that they offer if you bring your own domain.

Full-Stack Developer

It is very expensive if you have more than 5 or 10 domains and not all hosting providers give you the ability to create theses. And creating an email account for each of them is very anoying because we have to manage all accounts one by one etc. etc. With Zoho Mail I pay only about 10EUR per year to be able to get only one account and create an email address for each domain I have and receive all in one place

Chairman

All the standard protocol options are available, which makes this solution compatible with any mail user client software you prefer to use, from any web browser or the optional cross platform downloadable Zoho email client, or any standard mail (POP/SMTP) client you wish.  

Im summary, Zoho does not restrict the control you have over your email service and provides straight forward options for managing your service, is consistently reliable, and rich in features that you can add or remove yourself, as needed.

Consultant

The $16 annual price tag for a starter account is a wise choice in today's marketplace, making it perfect for any budget-conscious entrepreneur looking for a quality email domain provider that can also be coupled with a robust and cost-effective CRM.

Devoloper

I have used Zoho main for more than 6 months and it has great mail service and features for managing my calendar as well as tasks.

I also appreciate the strong security and threat detection, which gives me confidence in daily communication.

Marketing Director

I use my Zoho email as a forwarder basically so that i can have a custom domain but it all goes to my main gmail inbox which makes everything super convenient.

Also, the fact that I can activate an opening notification in case the other email accepts it is very useful too to track my opening rate without using a newsletter platform.

Researcher

The email and administrative functions (mail-admin and domain management) are not in the same interface, I have to browse two websites.

Zoho documentation is terrible, the chat function is gibberish, and the phone system is ALL voice mails.

Search is slow in large mailboxes, and mobile app notifications can lag.  

so you think you have no emails until someone says they sent you an email and you check or all of a sudden you have multiple emails flooding in

I might be mistaken, but I believe Zoho had all of this functionality and powerful control long before any of the bigger names in email services did, and even today I believe the others will be more expensive to unlock the features Zoho provides out of the box on the entry level plan.

Simple to use it and other Zoho products, great solutions for managing clients' requirements and sending messages and some small files

Product Owner

Also their email template options are a good addition. Since zoho has wide verity of product option, we can integrate them easily here.

owner

The app could use a couple more features such as blocking and reporting junk options but not a deal breaker.

I.T Administrator

The integration and ease of use, bringing in my other team as an administrator, and managing their workspace from my admin console, I'd say, are top-notch, whereby I could assign passwords and others to my team.

Craftsman

I was looking for an easy way to handle mail for my personal domain, and Zoho has great tools and options for making that happen.

Owner and Curator

I receive notifications when I should, and I feel confident that my emails are successfully sent.

I loved that I could set up email accounts using my business domain name for free.

Business Partner

another point compared to gmail zoho mail receipt of email with attachment timing is much slower in microseconds may be !

It’s a good Gmail replacement when you are guiding growing teams on a budget.

I was able to create a business email using my domain and Zoho provided all of the step by step instructions for my domain provider, and I am a newbie when it comes to advanced DNS settings.

internal risk and business control

Zoho Mail has a great delivery capacity, it operates under strict security that gives us protection and privacy in what is shared, it gives us all the tools to collaborate and communicate effectively, the technical support is agile and timely

Backend Developer

Zoho is the best when it comes to email management On top of it with zoho payrolls I can even create payrolls on a regular basis and send them in either mails or pdf format.

Associate Graduate Engineer

automatic spam detection and automatic threads deletion is handled carefully by the Zoho mail and security is also good and unwanted emails are detected automatically and moved to a separate folder.

Real Estate Seller

It has all the advantages of an email service such as spam filtering, virus, and malware protection, and custom signature.

MX records, email non repudiation and other security features and the procedure on how to set them where presented in a simple way with all the necessary information being available under account settings.

Sr. software engineer

Compared to some other email providers, Zoho Mail may have a more limited selection of third-party integrations While it's offers a range of advanced features but for learn that they don't have perfect and clean documentation. And For Mobile Application Zoho mail have different different app for like chat, For mail.

Secretary

In addition there is a view page which allows for printing when you don't want all that extra email errata clouding your print copy.

Admin

We are allowed to create a domain for our business and set up custom email addresses for our team that ensure a professional image!

Assitant Manager - Digital Marketing

Some of the more advanced functionalities are only available in the higher-tier plans for which you have to spend more.

Manager

Zoho offers great services for the price and the fact that you can integrate easily with other Zoho apps is an important thing to mention.

lack of response from support by trouble ticket, email, phone, or chat

Head of Digital

It is amazing how seamless the intergration between these products is and how user friendly the platform is, providing what seems like hundreds of different products. Although I have a technical background, many of my employees do not and yet they can manage customising and setting up new domains fine.

Web developer

Zoho Mail's clean UI, privacy focus and custom domains

Principal

Fast, reliable, feature-packed whether you get the application suite or start with the free e-mail service as I did.

the organization is nice and i like the way the words are readable the way it is displayed.

SEO Expert

Zoho Mail has redefined how I manage emails for the better, Its intuitive interface and seamless integration with other Zoho apps make email communication a breeze.

Only thing was the signature feature is slightly different when using mobile compared to using desktop

The feature I appreciate most is the accuracy of blocking spam emails.

One feature I really like about Zoho Mail, with the paid package, is the possibility to customize the domain name.

Inconsistent spam filtering performance

Software Engineer 

The least thing I like is the email spamming filter also the way of writing an email far away from services like Gmail.

47% of reviewers feel negative about Zoho Mail’s spam filtering. Some users report that the spam filter is either too aggressive—sending legitimate emails to the spam folder—or not effective enough, allowing unwanted messages into their inbox. Reviewers indicate that configuring spam settings can be confusing and time-consuming, and they often need to manually check or whitelist important contacts. Some reviewers say the volume of spam can become overwhelming, making the platform burdensome for daily use. They also mention that Zoho’s spam filtering does not match the effectiveness of other major email providers.

Affordable for small businesses

We use it to manage all our work emails in a fully secure environment.

Software developer and support

I mean, being able to read send email and received in a unified way as in GMail)

Developer

Sometimes it is difficult to find the way to access some of its features.

Adjunct Professor

In the case of Thunderbird, you can find a robust email client with functionalities at the level of many other paid clients. If I need to list Thunderbird's advantages, I will start by talking about its extensibility, making it one of the first email clients you can improve and customize with free third-party add-ons.

Coach

It offers all the features you might expect from a fairly lightweight email client.

CVOR Consultant

I like the ability to use and even build plug ins and add ons to enhance the experience.

Adding in calendar and task list to compete with Outlook was unnecessary.

Software Analyst

We started using Thunderbird as an alternative for our outlook clients, performing even better during the days, and making it a go-to software for our new installations.

If the best OSS email clients, it fast and almost without bug

Thunderbird is easy to use and offers valuable customer support.

Educator

It is good inbox managment software for the smaller companies or solo enterprenuers, but when you need to optimize some processess in your organization, it may lack integration abilities.

Product Manager

It is a lot more robust than other free software

so maybe it's better to say default styling is poor.

In general, my experience has been good, and I like this email manager tool.

Engineer

Creating and organizing your emails and folders is easy and intuitive.

Scientist

I opt to use other email clients over this as it is feature poor.

Anyway Thunderbird is a good program, but if you use a 365 email account I recommend Outlook instead.

Head of Brand and Innovation

Maybe too multi when you have a lot of accounts to manage.

Interface is a little clunky compared to competitors

It outperforms every other email client I have used.
