How to Forward Emails to Another Email Address

Email forwarding is one of those quietly powerful features that most people underuse. Whether you're consolidating accounts, redirecting work messages during a vacation, or routing emails from an old address to a new one, forwarding gives you control over where your messages land — without the sender needing to do anything differently.

What Email Forwarding Actually Does

When you forward an email, you're sending a copy of a received message to a different email address. That destination can be another account you own, a colleague's inbox, a shared team mailbox, or virtually any valid email address.

There are two distinct types of forwarding worth understanding:

• Manual forwarding — You open a specific email and choose to forward it to someone. This is a one-time action on a single message.
• Automatic forwarding — You configure a rule in your email settings so that all incoming messages (or those matching certain criteria) are automatically redirected to another address, without you touching each one.

Most people searching for "how to forward emails" actually want automatic forwarding — a set-it-and-forget-it setup. Both methods are straightforward, but they live in different places within your email client.

How to Manually Forward a Single Email

Manual forwarding works the same way across nearly every email platform:

1. Open the email you want to forward
2. Click or tap the Forward button (usually represented by an arrow pointing right)
3. Enter the destination email address in the "To" field
4. Add any message you want to include above the original content
5. Hit Send

The recipient receives the original message content, along with any attachments, formatted as a new email from you. This is the simplest version of forwarding and needs no configuration.

How to Set Up Automatic Email Forwarding

Automatic forwarding is where the real utility lies. The setup process varies by platform, but the logic is consistent across all of them.

Gmail

1. Go to Settings (the gear icon) → See all settings
2. Click the Forwarding and POP/IMAP tab
3. Select Add a forwarding address and enter the destination
4. Gmail sends a verification email to that address — the recipient must confirm it
5. Once verified, choose to forward all mail (and optionally keep a copy in Gmail or delete/archive it)

Gmail also lets you forward selectively using Filters. You can create a filter based on sender, subject, keywords, or other criteria, then apply the "Forward to" action — so only matching emails get redirected. 📬

Outlook (Microsoft 365 / Outlook.com)

1. Go to Settings → View all Outlook settings
2. Navigate to Mail → Forwarding
3. Toggle on Enable forwarding, enter the destination address
4. Choose whether to keep a copy of forwarded messages in your Outlook inbox

For rule-based forwarding (forwarding only certain emails), use Rules under Mail settings to define conditions and actions.

Apple Mail (iCloud)

1. Sign in at icloud.com → go to Mail settings
2. Under Preferences, find the Forwarding option
3. Enable forwarding and enter the destination address

Apple Mail on desktop (macOS) handles rule-based forwarding through Mail → Settings → Rules, where you can create conditions that trigger a forward.

Other Providers

Most email services — Yahoo Mail, Zoho, ProtonMail, Fastmail — include forwarding options somewhere in their settings under labels like "Accounts," "Filters," or "Mail Management." The terminology differs, but the underlying mechanism is the same.

Key Variables That Affect How Forwarding Works

Forwarding sounds simple, but several factors shape how it behaves in practice:

Forwarding vs. Aliases vs. Auto-Reply

These three features are often confused:

• Forwarding redirects incoming messages to a different address
• An email alias lets multiple addresses deliver to the same inbox — without forwarding at all
• An auto-reply sends an automated response back to the sender, but doesn't move the message anywhere

If your goal is simply receiving mail from two addresses in one place, an alias (where your provider supports it) may be cleaner than a forwarding chain. Forwarding introduces an extra hop that aliases avoid entirely. 🔄

When Forwarding Can Get Complicated

Automatic forwarding works smoothly for personal use, but a few scenarios introduce friction:

• Corporate IT policies often restrict or disable forwarding entirely on work accounts, particularly to external addresses. This is a security control, not a glitch.
• Forwarding chains — where Account A forwards to Account B, which forwards to Account C — can cause loops, delays, or delivery failures.
• High-volume accounts may hit forwarding limits set by the provider.
• Encrypted emails (like those using S/MIME or PGP) may not forward cleanly, since encryption is often tied to the original recipient's keys.

The Part That Depends on Your Setup

The mechanics of forwarding are consistent. What varies significantly is whether forwarding is the right tool for what you're actually trying to accomplish — and whether your specific accounts, domains, and IT environment will allow it to work cleanly.

A forwarding rule that works perfectly between two Gmail accounts may behave differently when one side is a corporate Microsoft 365 mailbox, an email hosted on a custom domain, or a service with strict DMARC policies. The destination platform's spam handling, the source platform's authentication setup, and any organizational policies in between all play a role. ⚙️

Understanding the type of forwarding you need, the platforms involved, and any restrictions on your accounts is what determines whether a simple toggle in settings is enough — or whether you'll need to troubleshoot a few extra layers.
