Why do some emails show a different “display name” than the actual address?
Still have a question, spotted an error, or have a better explanation or a source we should cite?
You've probably noticed this: an email shows up from "Netflix" but the actual address is something like no-reply@mailer.netflix.com. Or "Sarah from Acme Inc" but the address is sarah.jenkins@acme.com. The display name (what you see in bold) and the actual email address (what's in the headers) can be different because they're two separate fields in the From: header.
Here's how it works. When an email is sent, the From: header looks like this in the raw message:
From: Netflix <no-reply@mailer.netflix.com>
The part before the angle brackets is the display name. The part inside the brackets is the actual email address. Your email client (Gmail, Outlook, Apple Mail, whatever you're using) chooses to show you the display name because it's friendlier and easier to recognize. The raw address is still there if you dig into the message details, but most clients hide it by default.
Why do senders do this? Three reasons:
- Brand recognition. "Spotify" is way easier to spot than
notifications@email.spotify.com. - Human names. "Sarah from Support" feels personal even if the address is a shared queue like
support@company.com. - Technical routing. The actual address might route through subdomains for different email streams (marketing vs transactional), but the display name stays consistent.
But the catch: this is also how display name spoofing works. Scammers set the display name to "Your Bank" but use a completely unrelated address like totallylegit@randomdomain.xyz. Most people only look at the display name and assume it's real. That's why email clients now show little warnings when the display name doesn't match the domain, and why DMARC authentication matters so much for senders. If your domain isn't authenticated, inbox providers treat your display name with suspicion even if you're legit.
If you're setting up your own email sending, you get to pick both the display name and the address. Most ESPs (Mailchimp, Brevo, Postmark, etc.) let you configure this in your account settings. The display name should match your brand or the person your readers expect to hear from. The address should be on a domain you control and have properly authenticated.
