IMAP and SMTP settings for KPN Mail

Do you want to use your KPN email in an email program such as Outlook, Thunderbird or Apple Mail? Then you need the right server settings. Below you'll find the complete IMAP and SMTP configuration.

Setting Incoming mail (IMAP) Outgoing mail (SMTP)
Server imap.kpnmail.nl smtp.kpnmail.nl
Port 993 587
Security SSL/TLS STARTTLS
Authentication Normal password Normal password
Username Your full email address Your full email address
Password Your KPN password Your KPN password

POP3 settings (alternative)

Setting Value
Server pop.kpnmail.nl
Port 995
Security SSL/TLS

Difference between POP3 and IMAP

When you set up your email program, you choose between POP3 and IMAP. The difference matters:

  • IMAP synchronizes your email with the server. Changes (reading, deleting, folders) are applied on all your devices. This is the recommended setting if you read your mail on multiple devices.
  • POP3 downloads emails to your device and removes them from the server by default. This is only suitable if you read your mail on one device and want to keep a local copy.

Our advice: always choose IMAP, unless you have a specific reason to use POP3. With IMAP you have the same inbox everywhere.

Setting up KPN Mail in Outlook

Microsoft Outlook is one of the most popular email programs. Here's how to set up your KPN mail:

  1. Open Outlook and go to File > Add Account.
  2. Choose Manual setup or additional server types (in older versions) or enter your email address directly.
  3. Select IMAP as the account type.
  4. Under Incoming mail server, enter: imap.kpnmail.nl
  5. Under Outgoing mail server (SMTP), enter: smtp.kpnmail.nl
  6. Enter your full email address as the username.
  7. Enter your password.
  8. Click More Settings and go to the Advanced tab.
  9. Set the incoming port to 993 with SSL/TLS.
  10. Set the outgoing port to 587 with STARTTLS.
  11. Check the box that the outgoing server requires authentication (same settings as incoming).
  12. Click OK and then Next to test the configuration.

Setting up KPN Mail in Mozilla Thunderbird

Thunderbird is a free, open-source email program that works well with KPN Mail.

  1. Open Thunderbird and click Add Account (or go to Settings > Account Settings > Account Actions > Add Mail Account).
  2. Enter your name, email address and password.
  3. Click Configure manually.
  4. Enter the following details:
    • Incoming: IMAP, imap.kpnmail.nl, port 993, SSL/TLS
    • Outgoing: SMTP, smtp.kpnmail.nl, port 587, STARTTLS
  5. Select Normal password as the authentication method.
  6. Click Re-test to check the settings.
  7. Click Done if everything is correct.

macOS (Apple Mail)

  1. Open Apple Mail and go to Mail > Add Account.
  2. Choose Other Mail Account.
  3. Enter your name, email address and password.

@kpnmail.nl vs @kpnplanet.nl: what's the difference?

Over the years KPN has used several email domains:

  • @kpnmail.nl is the current standard email domain for KPN customers. New accounts are assigned this domain.
  • @kpnplanet.nl is an older domain that is still active for existing users. If you have had a @kpnplanet.nl address for years, it simply keeps working.
  • Other older domains such as @planet.nl and @hetnet.nl are also still used by some customers.

The server settings are the same for all KPN email domains. You always use imap.kpnmail.nl and smtp.kpnmail.nl, whether your address ends in @kpnmail.nl, @kpnplanet.nl or another KPN domain.

Keeping your email when you switch providers

A frequently asked question is: what happens to my KPN mail if I switch to another internet provider?

Good news: KPN lets you keep your email address after you cancel your internet subscription. This is how it works:

  • Your KPN email address stays available through KPN Mail Basis (free).
  • You can log in through webmail.kpn.com and the KPN Mail app.
  • IMAP and SMTP access remain available.
  • Your storage space may be limited on the free account.

Important: make a backup of important emails before you switch. Download them with an email program over IMAP or export them manually. That way you avoid data loss if something goes wrong during the transition.

Are you considering an independent email address that isn't tied to your provider? Then read on in the section about professional alternatives.

Troubleshooting KPN Webmail

Below you'll find solutions to the most common problems with logging in to and using KPN webmail.

Forgot your password

  1. Go to webmail.kpn.com and click Wachtwoord vergeten (Forgot password).
  2. Enter your email address.
  3. KPN sends a recovery email or text message to your linked contact details.
  4. Follow the instructions to set a new password.
  5. Use the new password to log in.

Note: after you change your password, you also need to update it in all your email programs and apps.

Forgot your KPN ID

Can't remember which email address you use as your KPN ID?

  • Check your old welcome email from KPN.
  • Call KPN customer service (0800-0402) and ask for your KPN ID.
  • Go to mijn.kpn.com and click KPN ID vergeten (Forgot KPN ID) to recover it with your phone number or customer number.

Error message when logging in

Getting an error message when you log in? Try the following:

  • Check your password: watch out for capital letters, spaces and special characters. If needed, use the option to show your password.
  • Clear your browser cache and cookies: outdated data can cause login problems.
  • Try another browser: some extensions or settings can cause conflicts.
  • Check whether KPN has an outage: look at allestoringen.nl or the KPN status page.
  • Turn off your VPN: KPN can sometimes block a VPN connection.

Sync problems

Do you receive emails on one device but not on another? This is often caused by incorrect settings:

  • Make sure you use IMAP everywhere (not POP3). POP3 downloads mail and removes it from the server, so other devices can no longer see the messages.
  • Check that the server settings are identical on all devices.
  • Remove your account from the email program and add it again with the correct IMAP settings.
  • Make sure your device is connected to the internet and that the sync interval isn't set too low.

Creating an app-specific password

If you have enabled two-step verification, some email programs won't accept your regular password. In that case you need an app password:

  1. Log in to mijn.kpn.com.
  2. Go to Instellingen (Settings) > Beveiliging (Security).
  3. Find the App-wachtwoorden (App passwords) option.
  4. Click Nieuw app-wachtwoord aanmaken (Create new app password).
  5. Give the password a recognizable name (for example "Outlook laptop").
  6. Copy the generated password and use it in your email program instead of your regular password.

Security tips for your KPN mail

Your email account contains sensitive information. Protect it with these tips:

  • Use a strong password: at least 12 characters with a mix of uppercase letters, lowercase letters, numbers and symbols. Never use the same password as for other accounts.
  • Turn on two-step verification: this adds an extra layer of security. Even if someone knows your password, they can't log in without the second verification. Read our guide on setting up two-step verification.
  • Watch out for phishing: KPN never asks for your password by email. Don't click suspicious links and always check the sender's address.
  • Log out on shared computers: using your webmail on a public or shared computer? Always log out and close the browser.
  • Keep your software up to date: always use the latest version of your browser, operating system and email program.
  • Check your account activity regularly: look for unknown login attempts or suspicious forwarding rules.

A professional email address on your own domain

A @kpnmail.nl address is fine for personal use, but for business purposes or if you want to be independent of your internet provider, an email address on your own domain is a much better choice.

Benefits of your own email domain:

  • Professional image: info@yourcompany.com makes a better impression than a free email address.
  • Independent of your provider: you never have to change your email address again when you switch internet providers.
  • Full control: you decide your own storage space, security settings and email limits.
  • Multiple addresses: easily create addresses for different purposes (info@, support@, personal@).
  • Better deliverability: emails sent from your own domain with correctly configured SPF, DKIM and DMARC arrive more reliably.

Frequently asked questions

How do I log in to KPN webmail?

Go to webmail.kpn.com in your browser. Enter your full email address (for example your.name@kpnmail.nl) and your password. Click Inloggen to access your inbox. You can also reach your email through mijn.kpn.com.

What are the IMAP settings for KPN Mail?

The incoming mail server is imap.kpnmail.nl on port 993 with SSL/TLS security. The outgoing mail server (SMTP) is smtp.kpnmail.nl on port 587 with STARTTLS. Use your full email address as the username.

What is the difference between POP3 and IMAP for KPN Mail?

With IMAP your emails stay on the KPN server and are synchronized across all your devices. With POP3 emails are downloaded to your device and removed from the server by default. IMAP is the recommended setting if you want to read your mail on multiple devices.

Can I keep my KPN email address if I switch providers?

Yes, KPN lets you keep your email address through KPN Mail Basis. This is a free service that keeps you connected to your @kpnmail.nl or @kpnplanet.nl address after you cancel your internet subscription. Always make a backup of important emails before you switch.

What do I do if I forgot my KPN password?

Go to webmail.kpn.com and click Wachtwoord vergeten. Enter your email address and KPN sends a recovery link to your linked contact details (email or text message). Follow the instructions to create a new password. Don't forget to update the password in your email programs as well.

Does @kpnplanet.nl still work?

Yes, @kpnplanet.nl addresses still work. This is an older domain that KPN used before. The server settings (imap.kpnmail.nl and smtp.kpnmail.nl) are the same as for @kpnmail.nl. You don't need to change anything if you have been using a @kpnplanet.nl address for years.

How do I set up KPN Mail on my iPhone?

Go to Settings > Mail > Accounts > Add Account > Other. Choose IMAP as the type, enter imap.kpnmail.nl as the incoming server (port 993, SSL) and smtp.kpnmail.nl as the outgoing server (port 587, STARTTLS). You can also download the KPN Mail app from the App Store for an easier setup.

What is an app password and when do I need one?

An app password is a specially generated password for email programs that don't support two-step verification. If you have enabled two-step verification on your KPN account, you can't log in to some programs with your regular password. In that case, create an app password at mijn.kpn.com under Beveiliging.

Why am I no longer receiving emails in Outlook?

First check that your internet connection works. Then check that your server settings are correct: imap.kpnmail.nl on port 993 (SSL/TLS) for incoming and smtp.kpnmail.nl on port 587 (STARTTLS) for outgoing. Also check whether your password was changed recently. If you use POP3 on another device, that may be the cause: POP3 removes mail from the server.

Is KPN webmail free?

Yes, KPN webmail is free for all KPN customers. You automatically get an email address with your internet subscription. Even after you cancel, you can keep your email address for free through KPN Mail Basis. The storage space on the free account may be more limited than on a paid subscription, though.

Summary

KPN webmail offers a simple, accessible way to manage your email, whether you work in the browser, the KPN Mail app or an email program such as Outlook, Thunderbird or Apple Mail. By using the right IMAP settings (imap.kpnmail.nl:993 and smtp.kpnmail.nl:587), you can synchronize your KPN mail across all your devices without any trouble.

Having trouble logging in? Check your password, clear your browser cache or create an app password if you use two-step verification. And don't forget: you can keep your KPN email address, even when you switch providers.

Want to go one step further and get a professional, provider-independent email address? Then consider an email address on your own domain. That way you are never dependent on your internet provider again and you always make a professional impression.

KPN webmail alternatives: more control over your email

KPN webmail is handy for basic email tasks, but it has limitations. If you regularly run into problems or want more functionality, consider these alternatives:

  • Outlook or Thunderbird: set up your KPN mail in a desktop client over IMAP. You get more storage space, better organization and offline access to your messages.
  • Gmail as a client: you can add your KPN email address to Gmail. In Gmail, go to Settings and Accounts and import your KPN mail over POP3.
  • Email on your own domain: for business use, an email address with your own domain name is more professional and more reliable. You don't depend on KPN and you keep your email when you move your domain.

With your own domain at Theory7 you get webmail, spam filtering and IMAP support for all clients in addition to email. Everything is included with your hosting plan.
