Outlook is the email app a lot of people end up with by default, because it ships with Windows and plugs into Microsoft 365. It is also an app some owners find more than they need. The Microsoft page I reviewed lists a free Outlook plan with 15 GB of mailbox storage and 5 GB of cloud storage. People look for Outlook alternatives when they want a lighter inbox, when they manage several accounts in one place, or when they want to stop paying for a bundle they barely use. I run my own stores and teach high-ticket dropshipping at Ecommerce Paradise, so I judge email apps by what they cost per year and whether a store owner can keep supplier threads, buyer questions, and invoices organized without extra work.
Everything below comes from each vendor’s own page as I reviewed it in October 2026. Where a page does not show a number, I write “not shown” instead of guessing. Prices and plans change often, so confirm them before you sign up. Some links in this article are affiliate links, which means I may earn a commission if you sign up, at no extra cost to you.
An email app supports a store, but it does not replace one. If you are still deciding what to sell, start with my guide to what high-ticket dropshipping is before you spend time on inbox tools.
Outlook Alternatives at a Glance
| Option | Starting price | Free option | Best for |
|---|---|---|---|
| Thunderbird | Free | Free, funded by donations | Owners who want a free desktop app with add-ons |

What Outlook Costs and Where It Falls Short
The Microsoft Outlook page lists a free plan for one person with email and calendar on web, desktop, and mobile. It lists 15 GB of mailbox storage and 5 GB of cloud storage. Paid options are Microsoft 365 Personal at $99.99 a year or $9.99 a month, and Microsoft 365 Family at $129.99 a year or $12.99 a month.
Personal covers 1 person on up to 5 devices with 1 TB of cloud storage, and Family covers 1 to 6 people with 2 TB of shared storage. The page lists Copilot drafting and summary features with Personal or Family. For a business address on your own domain, the Microsoft business page I reviewed for my Gmail alternatives guide lists Business Basic at $7 per user a month paid yearly.
The drawback for a store owner is that Outlook’s paid plans are part of a larger bundle. If you pay mainly to read email, you may be paying for storage and apps you never open. Prices also vary by country, so check the number at checkout.
How to Pick an Email App
Start with your accounts. If you juggle a store inbox, a supplier inbox, and a personal one, you want an app that combines them in one view. Some free versions cap the number of accounts, so check the limit first.
Next, think about devices. Some apps run on Windows and Mac only, while others add Android and iOS. If you check mail on your phone between calls, a mobile app that syncs matters.
Finally, think about the extras. Snooze, scheduled send, and email tracking save time once you handle many buyer questions. My guide to the best email signature software for ecommerce teams helps you keep your replies consistent as you add helpers.
1. Thunderbird
Thunderbird is a free email and productivity app that also handles calendars and contacts. The page says “Free forever” and states that it is funded by user donations. It is made by Thunderbird Technologies Corporation, which the page describes as part of the Mozilla family.
Features listed include one app for messages, calendars, and contacts, a unified inbox or separate accounts, filtering and tags, add-ons, and open-source code. Desktop platforms are Windows, macOS, and Linux, and the Android app is available through Google Play and F-Droid. An iOS version is not shown.
Thunderbird suits owners who want to pay nothing and are happy to set things up themselves. The page lists no paid tier, so your cost is time, not money.
2. eM Client
eM Client lists Free, Personal, and Business licenses. Free is $0 with registration, for 1 device and home use only, and it is limited to 2 email accounts with community forum support. Personal is $49.95 a year for one person on up to 3 devices, and Business is $59.95 a year per device for commercial use.
One-time options are listed too. Personal is $74.95 once and Business is $89.95 per device, and these cover the current major version. Lifetime Upgrades for future major versions are offered separately, and the price is not shown.
The page lists Windows and macOS desktop apps, with free Android and iOS apps that need no license. It also shows a 30-day free trial and a 30-day money-back guarantee on paid plans. The prices use a dollar sign without naming a currency, so confirm what you will be charged.
3. Mailbird
Mailbird lists a Free plan and a Premium plan. The free plan has no time limit and works with one email account and none of the Premium features. All features are free for 7 days, and each new account gets Premium free for its first 7 days.
The pricing page lists Premium at $4.03 per user a month paid yearly, with a higher crossed-out price shown beside it. A lifetime option is listed at $99.75 per user, shown against $399.00. Premium includes 1 user and 3 devices, a 14-day refund is offered, and a monthly price and business pricing are not shown.
Features listed include a unified inbox for Gmail, Outlook, iCloud, Yahoo, Proton, and IMAP accounts, snooze, scheduled send, and email tracking. Windows 10 and 11 are listed. The Mac version is described as coming through an early access program, and the mobile apps are in public beta, so availability is unclear.
4. Spark
Spark lists Free, Plus, Pro, and Enterprise plans. Plus is $10 a month or $99 a year, and Pro is $20 a month or $199 a year. The page also shows earlier figures of $120 and $240 a year that look like pre-discount prices, and Enterprise is not priced.
The free plan lists Smart Inbox, unlimited email accounts, smart notifications, and a calendar. Free users get a limited preview of the AI assistant. The table is hard to read in places, so some of these limits may not be exact.
Platforms listed are iOS, Mac, Windows, and Android, and a subscription bought on one platform works on the others. Plus and Pro list a 7-day trial when you subscribe directly in the app.
5. Gmail and Google Workspace
A personal Google Account lists up to 15 GB of storage shared across Gmail, Drive, and Photos, according to Google’s storage help page. For a custom domain, the Google Workspace pricing page lists Starter at $7 per user a month, Standard at $14, and Plus at $22.
Workspace lists a custom email domain on all three plans and a 14-day free trial. It also lists an introductory offer of 50% off for 3 months from November 9, 2026 to February 9, 2027, so check the live page. You can start with Google Workspace if you want Gmail on your own domain.
This route changes your inbox rather than just your app, since your mail lives in Google’s web tools. I compared more options in my Google Workspace alternatives guide.
What Each Option Costs Per Year
These figures are my own math from the listed prices. They leave out tax and any add-on the pages do not state, and where a page does not show a price I say so.
Microsoft 365 Personal is $99.99 a year, or $119.88 a year if you pay $9.99 monthly. Microsoft 365 Family is $129.99 a year, or $155.88 if you pay $12.99 monthly. eM Client Personal is $49.95 a year, Business is $59.95 per device a year, and the one-time prices are $74.95 and $89.95.
Mailbird Premium at $4.03 a month paid yearly is about $48.36 a year, and its lifetime price is $99.75. Spark Plus is $99 a year or $120 on monthly billing, and Spark Pro is $199 a year or $240 on monthly billing. Thunderbird is $0, a free Gmail account is $0, and Google Workspace Starter at $7 per user is $84 a year.
Which Option Fits Which Store Owner
If you want to pay nothing, Thunderbird lists a free app with no paid tier. A free Gmail account, eM Client Free, and Mailbird Free also cost nothing, though each limits what you get.
If you prefer a one-time purchase, eM Client lists one-time licenses and Mailbird lists a lifetime option. If you work across your phone and computer, Spark lists apps on four platforms with one subscription.
If you want your own domain address too, Google Workspace or Microsoft 365 business plans cover that. An email app alone does not give you a branded address.
Features Worth Paying For
Multiple accounts come first. If you run more than one store, you want one place to read everything. eM Client Free limits you to 2 accounts and Mailbird Free to 1, while Spark Free lists unlimited accounts.
Scheduling tools come second. Snooze and scheduled send let you answer a buyer at the right moment. Mailbird lists them under Premium.
Platform support comes third. If you rely on your phone, check that the mobile app is finished. Mailbird lists its mobile apps as public beta, while eM Client lists free Android and iOS apps.
Using Email Apps for a High-Ticket Store
High-ticket buyers write long, careful emails before they spend. They ask about delivery, warranty, and installation, and a fast, clear reply helps close the sale. An app that keeps these threads organized saves you from losing a large order in a crowded inbox.
Set up folders or labels for buyers, suppliers, and invoices. Save replies you use often, such as shipping times or return terms. If you sell on Shopify, you can route store notifications to a dedicated address and keep them out of your main inbox.
Do not tune your inbox before you know what you sell. My high-ticket niches list helps you pick a category first.
A Simple 30-Day Test Plan
Pick one app and add your main accounts. Use it for all your email for two weeks, including replying to buyers and supplier threads. Note anything that feels slow or missing.
Check search, because finding an old supplier quote quickly matters. Check that sent mail looks right on a phone. If you hit a free-plan limit, write down which one.
At the end of the month, repeat the test with a second app. Keep the one that fits how you work, and cancel anything you did not use.
Costs to Watch as You Grow
The first cost is the billing term. Spark lists a lower yearly price than monthly, and Mailbird lists a lower price on yearly billing. Read the renewal price before you click subscribe.
The second cost is per-device pricing. eM Client Business is priced per device, so adding helpers adds cost. Plan around the full price after any trial ends.
The third cost is the lifetime-versus-subscription choice. One-time prices cover a major version, and later versions may cost extra. eM Client lists upgrades separately.
Moving Away From Outlook Safely
Do not remove Outlook the day you try another app. Many of these apps connect to your existing mail account, so your messages typically stay on the server. Keep Outlook installed for a few weeks until you trust the new one.
Export contacts and calendar items you need, such as supplier details and delivery dates. Check that your signature and filters moved over, because those are easy to forget. Fix any gaps before you stop using the old app.
Tell the people you work with if you change your sending address. A short note prevents confusion over where to reply.
When Outlook Is Still the Right Pick
Outlook still makes sense in many cases. If your team already uses Word, Excel, and Teams, it fits neatly. The page lists attachment scanning, encryption that blocks forwarding of sensitive messages, and Copilot features with the paid plans.
If the free version covers your needs, there is little reason to pay for anything else. Match the tool to your work, and do not switch only because a list told you to.
Hiring Help With Your Inbox
Email is easy to hand off once you write down your rules. A virtual assistant from OnlineJobs.ph can sort the inbox, answer common questions from templates, and flag orders that need your attention. Give them a short guide and a few sample replies.
For a one-off job, such as building filters or a branded signature, a freelancer on Fiverr can be quicker than doing it yourself. Share access carefully and remove it when the job ends.
Common Mistakes With Email Apps
The first mistake is paying for a bundle when you only read email. The second mistake is switching apps without checking the account limit on the free plan.
The third mistake is using a store address before your company exists. If you have not formed your company, read my guide to business formation for high-ticket dropshipping. To file an LLC quickly, Bizee is one option I recommend.
The fourth mistake is polishing your inbox before you have suppliers. My guide to finding suppliers for high-ticket dropshipping covers what to line up first.
Frequently Asked Questions
What is the best free alternative to Outlook?
Thunderbird is listed as free forever and funded by donations. eM Client Free, Mailbird Free, and Spark Free also list free plans, each with limits.
How much does Outlook cost?
The Microsoft page lists a free Outlook plan. Microsoft 365 Personal is listed at $99.99 a year or $9.99 a month, and Family at $129.99 a year or $12.99 a month.
Is there a one-time purchase alternative to Outlook?

Mailbird lists support for Gmail, Outlook, iCloud, Yahoo, Proton, and IMAP accounts, and Thunderbird lists unified inbox support. Check each app’s page for your specific provider.
Do I need an email app as a small store owner?
Not always. If you use one inbox, a web inbox may be enough. An app helps once you manage several accounts or want features like scheduled send.
Final Verdict on Outlook Alternatives
Thunderbird is a good first test for owners who want a free app and are happy to configure it. eM Client suits owners who want a polished desktop client with one-time options, Mailbird suits owners who combine many accounts on Windows, Spark suits owners who work across devices, and Gmail with Workspace suits owners who want a web-first inbox with their own domain. Outlook is still worth keeping if your team already works in Microsoft tools every day.
Start with the free options, confirm the current price on each live page, and test with real messages before you cancel anything. Then put your attention back on the store, because an organized inbox only helps when the products behind it can sell.
