You got your business email. The address looks professional, the business name is right there, everything feels legit. Then you try to open it on your phone - and nothing works the way it's supposed to.

This guide exists for exactly that moment. It walks you through every step, on every device you're likely using - phone, computer, any operating system. Nothing is assumed. We start from the very beginning.

Why this is complicated in the first place

When you create a Gmail or Outlook.com account, everything sets itself up. You type in the email and password, and you're done.

Business email (the kind with your own domain, like name@yourbusiness.com) works a bit differently. It doesn't live on Gmail or Outlook servers - it lives on your hosting provider's server. That's why your phone and computer need to be manually "told" exactly where to look for that email, and how to connect to it.

That sounds more complicated than it actually is. In practice, you just need a handful of details, and then the same process applies on every device.

Basic terms, explained simply

Before we go further, here are a few terms you'll keep seeing throughout this guide, explained without technical jargon.

IMAP and POP3 are two different "languages" your device uses to agree with the server on how to pull your mail. We explain the difference in detail a bit further down.

SMTP is the "language" used only for sending mail - any device that sends emails needs SMTP details, even if it receives mail through IMAP.

A server is, simply put, a computer somewhere on the internet where your emails actually "live". When you type in "mail.yourdomain.com", you're telling your phone or computer exactly where to look for your mail.

A port is a number that determines which "door" your device uses to enter the server. Different types of connections (IMAP, POP3, SMTP) use different numbers, and if you type the wrong one, the connection simply won't work.

SSL/TLS and STARTTLS are ways the connection gets protected from unauthorized access, similar to a lock on a door. The device and the server need to agree on the same type of "lock", otherwise the connection won't go through.

What you need before you start

Before you open any app, get these details ready. You usually get them from your agency or hosting provider when the email account is created, often in a welcome email or in the hosting management panel (cPanel, Plesk, or similar).

• Full email address - for example name@yourbusiness.com
• Password - the one you were given or set yourself when the account was created
• Incoming mail server (IMAP or POP3) - usually something like mail.yourbusiness.com or imap.yourbusiness.com
• Outgoing mail server (SMTP) - usually the same server, but labeled smtp, for example smtp.yourbusiness.com
• Ports and security type (SSL/TLS) - numbers that determine how the device securely connects to the server

If you don't have these details on hand, don't worry - further down we explain exactly where they're usually found, and give the typical values that apply to most hosting providers.

Where to find these details

The most common place is cPanel (your hosting's control panel) - inside it there's a section called Email Accounts, and next to each account a button called Connect Devices. Clicking that button automatically shows you all the details you need, specific to your account.

If you don't have access to cPanel, ask directly for these details from the person or agency who set up your website and email - they're usually in the same email where you received your login credentials.

Typical server settings (if you can't find the exact ones)

Replace "yourdomain.com" with your actual domain. The username for login is always the full email address (name@yourdomain.com), not just "name".

Quick reference - remember these five things

If you remember nothing else from this text, remember these five things - they solve ninety percent of all problems:

• The username is always the full email address, never just the name.
• Use IMAP, not POP3, if you check mail from more than one device.
• The incoming and outgoing mail server is usually the same (mail.yourdomain.com), just with a different port.
• Port 993 is for IMAP, port 587 or 465 is for SMTP (sending).
• If something doesn't work, check the port and security type (SSL/TLS or STARTTLS) first - that's the cause in most cases.

If you have several employees or several email addresses

If your business has multiple people, each person usually has their own email address (firstname.lastname@yourbusiness.com) and their own password - everyone sets up their own account on their own phone or computer, entirely independently, following the exact same steps in this guide.

New accounts for employees are created by the hosting administrator (you, through cPanel, or the agency managing your hosting) in the Email Accounts section - by simply entering an account name and password. Each new account then follows the exact same setup process described in this text, just with a different email address.

If you want one person (say, you, as the owner) to also see other employees' mail, that's handled through the Forwarders option in cPanel, or by adding that other email address as an additional account on the same phone - both accounts then run independently, side by side.

IMAP or POP3 - which one to choose

IMAP keeps all your emails on the server, and the device just "looks" into them. That means if you delete an email on your phone, it's deleted on your computer and in webmail too - the same everywhere, at every moment. This is the recommended option for almost everyone, especially if you check mail from more than one device.

POP3 downloads emails from the server to the device, and (depending on settings) often deletes them from the server afterward. That means if you open an email on your phone through POP3, you might not see it later on your computer at all. POP3 only makes sense if you use exclusively one device and want your emails physically stored on it.

For almost anyone reading this, the recommendation is clear: use IMAP, everywhere, on every device.

First, check what type of business email you have

There are two different "types" of business email, and it matters which one you have before you continue, because the steps differ.

The first type is email that comes directly from your hosting (cPanel, Plesk, or similar) - that's the situation everything explained so far applies to, along with everything that follows in this guide.

The second type is email hosted on Google Workspace (formerly G Suite) or Microsoft 365, even though it still uses your domain (name@yourbusiness.com). In that case, setup is much simpler, because it uses a Google or Microsoft sign-in instead of manually entering server details. If you're not sure which type you have, check the sections below - you'll recognize your situation easily.

If your business email runs on Google Workspace

You'll recognize this if you were given access through a Google sign-in when your account was created, or if you already use the Gmail interface with your @yourbusiness.com address.

1. On your phone, open the Gmail app and add an account the same way you would for a regular Gmail account - tap your profile picture, then Add another account, then choose Google (not "Other").
2. Enter your business email address and password, as if signing into a regular Google account.
3. On your computer, simply sign into gmail.com with the same address and password, or add the account in Outlook/Mail by choosing Google instead of Other - there's no need for manual server and port entry.

Everything else (Calendar, Docs, Drive) comes automatically with the same account, since it's the full Google Workspace package.

If your business email runs on Microsoft 365

You'll recognize this if you sign in through outlook.office.com or if your account was set up through a Microsoft 365 subscription.

1. On your phone, install the Outlook app (or use the built-in Mail app), and add the account by choosing Office 365 or Microsoft 365, instead of manual IMAP setup.
2. Enter your email address and password - the phone will redirect you to the standard Microsoft sign-in, including two-factor authentication if it's enabled.
3. On your computer, the Outlook desktop app works identically - add the account, enter the address, and everything else is configured automatically.

For both of these cases (Google Workspace and Microsoft 365), you don't need the manual server, port, or SSL setup described in the rest of this text - that only applies to email coming directly from hosting (cPanel type). If you're unsure which type you have, the safest bet is to first try the regular Google or Microsoft sign-in (described above) - if it works, you're done. If it doesn't, continue with the guide below, which is meant for self-hosted email.

The fastest way - webmail through your browser

Before setting anything up on your phone or computer, know that there's always the fastest possible way to check your mail - directly through a web browser, with no installation at all.

1. Open a browser (Chrome, Safari, Edge - any of them) and type in webmail.yourdomain.com (replace "yourdomain.com" with your actual domain).
2. If that address doesn't work, try yourdomain.com/webmail or yourdomain.com:2096.
3. Enter your full email address and password.
4. An interface opens (usually Roundcube or Horde) where you see all your mail, much like Gmail.

This is a great solution for checking mail instantly from any computer, even someone else's, since it requires no installation or setup - just an internet connection. For everyday use, though, it's more convenient to have email directly in an app on your phone and computer, so let's continue with that.

Adding email to an Android phone

On Android phones, the Gmail app is most commonly used (it supports other email accounts too, not just Gmail), or the built-in Email app that came with the phone. The steps are nearly identical for both.

1. Open the Gmail app (or Email, depending on the phone).
2. Tap your profile picture in the top right corner, then Add another account.
3. When offered options (Google, Yahoo, Outlook...), choose Other or IMAP/POP setup.
4. Enter your full email address and tap Next.
5. Choose the account type - Personal IMAP is recommended.
6. Enter your password.
7. On the Incoming server settings screen, enter:
   • Server: mail.yourdomain.com (or the exact detail you were given)
   • Port: 993
   • Security type: SSL/TLS
8. On the Outgoing server settings screen, enter:
   • Server: mail.yourdomain.com (SMTP)
   • Port: 465 or 587
   • Security type: SSL/TLS or STARTTLS
   • Make sure "Require sign-in" is enabled, with the same email address and password
9. Tap Next, wait for the phone to verify the connection, and set the account name and the display name recipients will see when you send mail.
10. Tap Finish setup.

If your phone shows an error at this step, the most common cause is a wrong port or an incorrectly chosen security type - more on that in the errors section further down.

If you're using the Samsung Email app instead of Gmail

Samsung phones often come with their own built-in Email app, which works the exact same way:

1. Open the Email app, and if this is your first account, it will show you the setup screen directly. If you already have an account, go to Settings (inside the app, gear icon) > Add account.
2. Choose Other from the list of providers.
3. Enter your email address and password, then choose Manual setup if offered.
4. Fill in the IMAP and SMTP details exactly as in the previous steps for the Gmail app.

Adding email to an iPhone (iOS)

On iPhone, email is added through the phone's settings, not through the Mail app itself.

1. Open Settings on the phone.
2. Scroll down and tap Mail.
3. Tap Accounts, then Add Account.
4. From the list of options (iCloud, Google, Outlook...), choose Other, at the very bottom of the list.
5. Tap Add Mail Account.
6. Enter your name, full email address, password, and a description for the account (e.g. "Business email"), then tap Next.
7. The phone will try to find the settings automatically - if it fails, fields for manual entry will appear.
8. Choose IMAP at the top of the screen (recommended, instead of POP3).
9. Under Incoming Mail Server, enter:
   • Host Name: mail.yourdomain.com
   • User Name: your full email address
   • Password: your password
10. Under Outgoing Mail Server, enter:
    • Host Name: mail.yourdomain.com
    • User Name: your full email address
    • Password: your password
11. Tap Next. The phone will try to verify the account (Verifying).
12. If a security certificate warning appears, choose Continue - this is common with smaller hosting providers and doesn't mean anything is wrong.
13. Tap Save.

If emails still don't arrive afterward, check the port and security setting manually: tap the new account in Mail settings, open SMTP under the outgoing server, and check that the port and SSL are set to the same values as in the table earlier in this text.

Adding email on a Windows computer (Outlook)

Outlook is the most commonly used app for email on business computers. There are two versions - a new (simpler) one and a classic (desktop) version, depending on which one you have installed.

New Outlook app (Windows 11 and newer)

1. Open the Outlook app.
2. Click Add account, usually in the bottom left corner or in the File menu.
3. Enter your full email address and click Connect.
4. If the app doesn't recognize the account automatically, it will offer Advanced settings - click on it.
5. Choose IMAP.
6. Enter the incoming mail details (server, port 993, SSL) and outgoing mail details (server, port 587 or 465, SSL/STARTTLS), same as in the table earlier in the text.
7. Enter your password when prompted.
8. Click Connect / Done.

Classic Outlook (desktop version, part of Microsoft 365 or Office)

1. Open Outlook and go to File > Add Account.
2. Enter the email address and click Connect.
3. If asked to choose an account type, select IMAP.
4. If manual setup is required, enter:
   • Incoming mail server (IMAP): mail.yourdomain.com, port 993, encrypted connection SSL/TLS
   • Outgoing mail server (SMTP): mail.yourdomain.com, port 587 (or 465), encrypted connection STARTTLS (or SSL/TLS for 465)
5. Enter your username (full email address) and password.
6. Click Next, then Finish once the connection is confirmed.

Note: if Outlook keeps asking for your password over and over, even though you're entering it correctly, the most common cause is a wrong port for outgoing mail (SMTP) - check whether you're using 587 with STARTTLS or 465 with SSL, and that they're not mixed up.

Alternative: the built-in Windows Mail app

If you don't use Outlook, Windows comes with a free Mail app that works the same way:

1. Open the Mail app (search for it through the Start menu if you don't see it on the desktop).
2. Click Accounts in the left menu, then Add account.
3. Choose Advanced setup, then Internet email.
4. Fill in every field - email address, username (full address), password, incoming and outgoing server, ports, and encryption type - same as in the table.
5. Click Sign in, then Done.

Adding email on a Mac computer

Mac computers have a built-in Mail app, which is simple to set up.

1. Open the Mail app.
2. If this is your first account, the app itself will show the add-account screen. If you already have an account, go to Mail in the top menu, then Preferences (or Settings), then Accounts, and click the plus (+) in the bottom left corner.
3. From the list of providers, choose Other Mail Account.
4. Enter your name, full email address, and password, then click Sign In.
5. If Mail can't find the settings automatically, it will ask for manual entry:
   • Incoming mail server: mail.yourdomain.com
   • Outgoing mail server: mail.yourdomain.com
6. Click Sign In again, and wait for the account to be confirmed.
7. Choose which apps should have access to the account (Mail, Notes, Calendar...) and click Done.

If a message appears saying the server can't connect over SSL, open Account Settings > Server Settings, and manually check the ports (993 for IMAP, 587 or 465 for SMTP), and that the SSL checkboxes are enabled.

Alternative for every platform: Mozilla Thunderbird

Thunderbird is a free email program for Windows, Mac, and Linux, and is often simpler to set up manually than Outlook, since it shows everything on one screen.

1. Download and install Thunderbird from the official website (thunderbird.net).
2. On first launch, or through the menu Tools > Account Settings > Add Mail Account, enter your name, email address, and password.
3. Click Continue. Thunderbird will try to find the settings automatically.
4. If it fails (common with smaller hosting providers), click Manual config.
5. Fill in exactly: IMAP server, port 993, SSL/TLS for incoming mail; SMTP server, port 587 or 465, STARTTLS or SSL/TLS for outgoing mail; username - full email address for both.
6. Click Done - if a risk warning appears, confirm you want to continue, since this is common with smaller servers.

Common errors and how to fix them

Almost every error during email setup falls into one of these few categories. Here's what they usually mean and how to fix them.

"Incorrect username or password" even though the password is correct. The most common cause is entering just "name" instead of the full email address "name@yourdomain.com" in the username field. For business email, the username is always the full address.

"Server not responding" or "Connection timed out". This usually means the port is wrong, or the wrong security type is selected (SSL instead of STARTTLS, or the other way around). Check the settings table earlier in this text and try again with the correct values.

Emails arrive, but I can't send. The reason is almost always the SMTP (outgoing) server - either the port is wrong (587 instead of 465, or vice versa), or the option requiring the SMTP server to authenticate with a username and password isn't enabled.

Security certificate warning. With smaller hosting providers, the server's certificate sometimes doesn't exactly match the domain name (e.g. the server is called server123.hosting.com instead of mail.yourdomain.com). This is common and generally safe to continue past, as long as you're sure you entered the correct details from your hosting provider.

I see emails on my phone but not on my computer (or vice versa). This almost always means one device is set to IMAP and the other to POP3. Check and switch both to IMAP, so every device shows exactly the same state.

Emails don't arrive instantly, they're delayed by a few minutes. This is normal behavior for some apps that check mail at intervals (say, every 5-15 minutes) rather than instantly. Check the sync settings inside the app and shorten the interval if you want faster notifications.

How to check that everything is set up correctly

After finishing setup on any device, run this quick test to make sure everything works properly, instead of waiting and hoping.

1. Send yourself a test email - easiest is from that same address to that same address (name@yourdomain.com sends to name@yourdomain.com).
2. Check whether it arrives in your Inbox within a few minutes.
3. If you don't see it in the Inbox, check the Spam or Junk folder - this is normal on the first test.
4. Then ask someone else (a friend, a colleague) to send you an email from their address, to confirm external mail arrives correctly too, not just the mail you send to yourself.
5. Finally, send a test email with an attachment (say, one photo), to confirm sending attachments works without errors too.

If all of these steps pass without issues, the setup is fully complete and the email account is ready for everyday use.

Additional errors you might run into

Emails I send to clients end up in their Spam folder. This usually isn't a problem with the account setup on the phone or computer, but rather with the domain's reputation or missing SPF/DKIM records on the server itself. This gets fixed at the hosting level (DNS settings), not on the device - if you notice this issue, contact your agency or hosting provider.

I can't send a large attachment (file). Most mail servers have a size limit for attachments, usually between 10 and 25 MB per email. If your file doesn't fit, try compressing it (into a ZIP file), splitting it into several smaller files, or using a file-sharing service (Google Drive, WeTransfer) and sending just the link.

The account keeps "signing out" on its own on my phone. This sometimes happens if the phone has an aggressive battery-saving mode enabled, which closes background apps. Check the battery settings for that app (Settings > Battery > [app name]) and disable restrictions for that specific app.

A few words about password security

Since business email often contains sensitive information about your business and clients, it's worth spending a minute on security.

• Use a password that isn't used for any other account (not personal email, not social media).
• Avoid obvious passwords like the business name, a birth date, or "123456".
• If your hosting offers two-factor authentication (2FA) for webmail, turn it on - it adds a layer of protection even if someone learns the password.
• If you share a computer with others (say, a shared office computer), always sign out of webmail after using it.

Frequently asked questions

Can I have email on my phone and computer at the same time? Yes, without limitation. That's exactly the advantage of IMAP - every device shows the same state, in real time.

Is it safe to enter my business email password into the Gmail or Outlook app? Yes. These apps only use standard, secure protocols (IMAP/SMTP over SSL) to connect to your server - they don't share your password with Google or Microsoft, nor do they store it on their servers.

What if I forget my password? Business email accounts usually don't have a "forgot password" option like Gmail. The password gets changed through cPanel (Email Accounts > Manage > Reset Password) or through the person/agency managing your hosting.

What's the difference between ports 587 and 465? Both are used for sending mail (SMTP), just with different encryption - 587 usually uses STARTTLS, and 465 uses SSL/TLS from the very start of the connection. If one doesn't work, always try the other.

Does POP3 delete emails from the server? Depends on the setting, but by default - yes, it often removes them from the server after downloading to the device. That's why IMAP is recommended, since it doesn't delete anything automatically.

Why does my phone keep asking for the password over and over? Most commonly due to a wrong port or security type for outgoing (SMTP) mail, or because the password isn't entered correctly (check there's no space before or after the password when you copy it).

Can I use the same email account on multiple phones at once? Yes, with no limit on the number of devices. All you need is to enter the same details on each device (email address, password, server settings).

Do I need internet to see old emails? With IMAP, the device usually keeps a local copy of already-downloaded emails, so you can read them without internet - but for new emails and sending, an internet connection is required.

What's an "alias" email address, and do I need one? An alias is an additional address (e.g. sales@yourbusiness.com) that arrives in the same main account, with no separate password or device setup needed. If you need one, it's created through cPanel (Email Accounts > Forwarders) or through the agency managing your hosting.

Do I need to install anything special to keep email secure? No. IMAP, POP3, and SMTP over an SSL/TLS connection (which we've used throughout this guide) are already encrypted and secure on their own. It's enough to use a strong password and not share it with anyone.

Why am I not getting notifications for new emails on my phone? Check two places: first, inside the mail app's account settings, that notifications are enabled for that specific account. Second, in your phone's general settings (Settings > Apps > [app name] > Notifications), that the phone isn't blocking that app's notifications at the system level.

What if I entered everything correctly and it still doesn't work? Check whether you accidentally typed an uppercase letter instead of lowercase in the email address or server, check there's no space at the start or end of any field, and try restarting the app or device after entering the details. If that still doesn't help, contact whoever manages your hosting - exact settings can vary slightly depending on the hosting provider.

In closing

The first time you set this up, it feels like a lot of steps for something that should be simple. But once you've entered the correct details, email runs completely automatically, on every device, with no further setup needed going forward.

If you get stuck on any step, it's perfectly fine to ask for help - this guide covers the vast majority of cases, but every hosting provider has its own small differences in exact server names and settings.
