Managing multiple Fastmail accounts can be challenging, especially when you use different email addresses for work, personal communication, and business activities. Switching between inboxes, keeping track of important messages, and organizing separate accounts can make everyday email management more complicated.
Fortunately, there are several ways to manage multiple Fastmail accounts efficiently. You can use Fastmail's built-in account-switching features, separate browser profiles, or a dedicated desktop environment to keep your inboxes organized.
In this guide, we'll explore how to manage multiple Fastmail accounts and how WebCatalog can help simplify your email workflow on your desktop.
Why Use Multiple Fastmail Accounts?
Fastmail is an email service designed for personal and professional communication, offering features such as custom domains, calendars, contacts, email aliases, and inbox organization tools.
Using multiple Fastmail accounts can help you separate different types of communication and maintain a more organized workflow.
Some common reasons include:
- Work and personal communication: Keep professional emails separate from personal conversations.
- Business management: Use different email accounts for clients, departments, or business activities.
- Project organization: Maintain dedicated inboxes for different projects or responsibilities.
- Multiple organizations: Access email accounts associated with different companies or teams.
- Privacy and organization: Keep different types of communication separate to reduce inbox clutter.
Fastmail also supports email aliases, which let you use additional email addresses without creating separate user accounts. If you need independent inboxes and login credentials, separate Fastmail users may be more appropriate.
Challenges of Managing Multiple Fastmail Accounts
Using several Fastmail accounts can introduce a few common challenges.
1. Switching Between Accounts
Although Fastmail supports switching between logged-in accounts, frequently moving between different inboxes can interrupt your workflow.
2. Managing Separate Sessions
Keeping track of different accounts across browser tabs, profiles, or windows can become confusing.
3. Missing Important Emails
When messages arrive in separate inboxes, it can be easier to overlook important emails or notifications.
4. Reduced Productivity
Repeatedly navigating between accounts can take time and make everyday email management less efficient.
Fortunately, there are several methods to simplify the process.
Method 1: Manage Multiple Fastmail Accounts Using a Web Browser
One of the simplest ways to manage multiple Fastmail accounts is through Fastmail's built-in account-switching feature.
Step 1: Open Fastmail
Visit Fastmail and sign in through its web interface.
Step 2: Sign In to Your First Account
Enter your Fastmail email address and password to access your inbox.
Step 3: Open the Account Menu
Click your profile avatar in the upper-right corner of the Fastmail interface.
Step 4: Add Another Fastmail Account
Select Add another account, then choose the option to log in as another user.
Enter the credentials for your second Fastmail account.
Step 5: Switch Between Accounts
Click your profile avatar and select the account you want to access.
Fastmail allows multiple users to remain signed in simultaneously, so you can switch between their inboxes without repeatedly logging out.
Limitations of this method:
- You still need to switch between accounts within the Fastmail interface.
- Managing multiple browser tabs can create desktop clutter.
- It may be harder to maintain distinct workspaces for different projects.
- Organizing Fastmail alongside other productivity apps may require additional browser management.
For users who prefer dedicated desktop environments, WebCatalog provides another option.
Method 2: Manage Multiple Fastmail Accounts with WebCatalog
WebCatalog allows you to turn websites into desktop apps and manage multiple accounts through separate app sessions.
Instead of keeping several Fastmail accounts open in different browser windows, you can create dedicated environments for your email accounts and access them from your desktop.
Step 1: Download and Install WebCatalog
Visit WebCatalog and download the desktop application for your operating system.
Install WebCatalog and launch it on your computer.
Step 2: Find Fastmail
Open WebCatalog and search for Fastmail in the app catalog.
You can also visit the Fastmail app page on WebCatalog.
Step 3: Create Your First Fastmail App
Add Fastmail as a desktop app and sign in with your first email account.
For example, you might use this account for personal communication.
Step 4: Add Another Fastmail Account
Create another separate Fastmail app instance or profile using the account-management options available in your WebCatalog version.
Sign in with your second Fastmail account.
Each isolated session can maintain its own login information, allowing you to access different inboxes without repeatedly signing out.
Step 5: Organize Your Fastmail Accounts
Give each account a recognizable name, such as:
- Fastmail – Personal
- Fastmail – Work
- Fastmail – Business
- Fastmail – Projects
You can also use spaces in WebCatalog to organize your email accounts and other applications into separate workspaces.
Step 6: Switch Between Accounts
Open the Fastmail app instance associated with the account you want to use.
With separate sessions, you can switch between inboxes while keeping their login information independent.
Benefits of Using WebCatalog for Multiple Fastmail Accounts
1. Keep Accounts Separate
WebCatalog supports isolated app sessions, helping different Fastmail accounts maintain independent login information.
This can be useful when managing personal, professional, and business email accounts.
2. Switch Between Accounts More Easily
Access your Fastmail inboxes through dedicated desktop app environments.
As long as your sessions remain active, you can switch between accounts without repeatedly entering your credentials.
3. Organize Your Desktop Workspace
Spaces in WebCatalog let you group related applications and accounts into organized workspaces.
For example, you can organize Fastmail alongside Google Calendar, Notion, and Slack.
4. Reduce Browser Clutter
Instead of keeping multiple Fastmail tabs open in your browser, you can access your inboxes through dedicated desktop app windows.
5. Manage Multiple Email Services in One Place
WebCatalog also allows you to organize other web-based email services alongside Fastmail.
For example, you can manage Gmail, Outlook, Yahoo Mail, and Proton Mail within the same desktop environment.
This can be particularly useful for freelancers, business owners, and professionals who regularly manage multiple email accounts across different providers.
Method 3: Manage Multiple Fastmail Accounts Using an Email Client
Another option is to configure multiple Fastmail accounts in a compatible email application.
Fastmail supports IMAP and SMTP access on eligible plans, allowing users to connect their email accounts to third-party clients.
Step 1: Choose an Email Client
Open an email application that supports multiple accounts, such as Microsoft Outlook, Apple Mail, or Mozilla Thunderbird.
Step 2: Check Your Fastmail Plan
Make sure your Fastmail subscription supports third-party email clients.
Fastmail Basic plans do not include IMAP or SMTP access.
Step 3: Generate an App Password
Sign in to Fastmail and navigate to Settings → Privacy & Security.
Under Connected apps & API tokens, select Manage app passwords and access, then create a new app password.
Step 4: Add Your First Fastmail Account
Follow your email client's setup instructions and use the generated app password when prompted.
Step 5: Add Another Fastmail Account
Repeat the process for your second Fastmail account, generating the appropriate app password for the email client.
Step 6: Organize Your Mailboxes
Use separate inboxes or a unified inbox, depending on the features available in your email client.
Limitations of this method:
- Third-party email client access requires an eligible Fastmail plan.
- Each external application needs its own app password.
- Some Fastmail web features may not be available in third-party clients.
- A unified inbox may make it harder to distinguish messages from different accounts.
For users who prefer Fastmail's web interface, WebCatalog provides a way to organize separate desktop sessions without configuring IMAP.
Tips for Managing Multiple Fastmail Accounts Efficiently
A few simple habits can help you manage your inboxes more effectively.
Use descriptive account names. Clearly distinguish personal, professional, and project-related accounts to avoid confusion.
Organize emails with folders and rules. Use Fastmail's inbox organization features to categorize messages and find important emails more easily.
Consider email aliases. If you only need additional addresses rather than independent inboxes, Fastmail aliases may be a simpler solution.
Enable two-factor authentication. Protect your Fastmail accounts with strong, unique passwords and additional security features.
Check important inboxes regularly. Establish a routine for reviewing messages across your accounts.
Keep work and personal communication separate. Use different app sessions or workspaces to maintain a clear distinction between your activities.
Review notification settings. Configure available email notifications to stay informed without unnecessary interruptions.
