If I Forward an Email, Can the Sender See It?
The answer is “no,” in most cases, the original sender won’t know you’re forwarding their email.
For traditional emails, such as those you send to and receive from individuals, there is no notification or alert to the originating sender that you are forwarding their message.
Let’s look at the exceptions in more detail before you decide whether or not to forward the message.
💡 Note: Any instructions, features, or menu options you see below apply to the web versions of Gmail and Microsoft Outlook. All other details apply to forwarding on any device.
When Does Forwarding an Email Notify the Original Sender?
Although most times, the sender of a message won’t know that you forward it, here are a few instances when they might be notified or become aware of the forwarding.
Email Interaction
Spammers can use tools to find out if an email account is active. This can include things like downloaded inline images within a message (including tracking pixels). If a spammer finds out that your account is active because you opened the email, they may also be able to detect that the recipient you forward the message to has an active account as well.
Tracking Pixels
Tracking pixels are tiny images that marketing and advertising companies insert into messages. These pixels can track things like when an email is opened. If you forward a message that contains a tracking pixel, this can indicate to the original sender that the email has been opened again.
Server Logs
Many large companies and especially those dealing with sensitive or confidential information can keep track of what happens to emails within the company. This may allow them to track the recipient and destination of a message that is forwarded and then notify the original sender if requested.
What Does Forwarding an Email Do?
When you forward a message or an email thread, you’re sending it to a new recipient. Your service provider adds certain indicators and may include attachments by default. Additionally, the message is sent in its entirety including the original sender’s name and/or email address.
These are important considerations when forwarding emails. For instance, if you don’t want your recipient to know you’re forwarding the message, you may want to alter it first. As for attachments, you might need to remove them if they contain personal information or confidential data as described later.
Forwarding Indicators
First, you’ll notice “Fw“or “Fwd” added to the beginning of the subject line to show your recipient that they’re receiving a forwarded message. With most email services, you can edit the subject line to remove that text.
Next, you’ll see something like “Forwarded message” or a separator line between what you add to the email and the original message beneath. Like earlier, this is something that you can normally edit or remove before hitting the Send button.


Forwarding Attachments
As for attachments, service providers can work a bit differently. For instance, in Gmail and Outlook, attachments are included by default. But, you can select the attachment and click the X or choose Remove (Attachment) in the toolbar or drop-down menu.
In most cases, inline images are included with forwarded messages as these aren’t considered separate attachments.
Forwarding Original Message Details
One more consideration when forwarding an email is the details included from the original message.
Below the Forwarding Indicator in the body of the message, you’ll see the original sender which can display their name and email address.
Along with the sender details, you can see any recipients who were copied (CC) on the original message. This can also include names and email addresses.
Finally, you’ll see the original date and time for the message.


All of these details are shown to your new recipient when you forward the message. However, you can remove this information to keep the original sender, copied recipients, and timestamp private.
💡 Note: Recipients who are blind copied (BCC) on the original message do not display when forwarding.
What Security Issues Can Email Forwarding Cause?
Before you forward a message, there are two other things to think about and those are privacy and security. If you aren’t careful, you could wind up in legal trouble for sharing something you shouldn’t.
If you forward a message that contains personal information such as an individual’s login credentials, financial data, health information, account numbers, or similar secure details, this can be considered a privacy breach.
Another consideration is passing along a company’s confidential information such as trade secrets which can also lead to privacy violations.
Finally, if you forward a message that unbeknownst to you contains malicious links or attachments, then you’re opening your forwarding recipient to these digital dangers which can result in repercussions.
The bottom line is that if you’re unsure, either ask permission from the original sender to forward the email or create a brand-new message paraphrasing the details.
