Why Gmail Shows "via" Next to Your Name (and How to Remove It)

Gmail shows "via" and another domain next to your name when the message was sent or signed by a service whose domain does not match your From address, for example "via sendgrid.net". The fix is to set up custom DKIM so the sending service signs your mail with your own domain; once the signature matches, the label disappears.

What the label looks like

In Gmail, the sender line reads something like Sam Example <sam@example.com> via mailplatform.net.

Gmail is telling the reader: this says it is from example.com, but it was authenticated by mailplatform.net. Gmail's help documentation describes the label as appearing when the sending domain and the domain in the From address do not match.

Why it happens

When you send through an email platform without authenticating your domain, the platform still needs to sign the message so it is not rejected. It signs with its own domain, using its own DKIM key, and often uses its own return-path for bounces. The message passes DKIM for the platform's domain, not yours.

Common sources:

Sender	Typical cause
Marketing platform on its default settings	Domain authentication never completed
CRM or sales tool sending as you	Uses its shared sending domain
Help desk sending ticket replies	Signs with its own domain
Website contact form or app emails	Sent through a hosting provider's mail server
Calendar or invoicing tools	Send notifications "from" your address

Why you should fix it

• Trust. Some readers notice "via" and treat the email with suspicion, especially in finance, healthcare or anything involving payments.
• DMARC alignment. The same mismatch that causes "via" usually means DKIM does not align with your From domain. If SPF also uses the platform's return-path, DMARC fails. What is DMARC alignment explains why that matters.
• Gmail's sender rules. Gmail requires bulk senders to pass DMARC with alignment. Unaligned mail risks filtering. See Gmail and Yahoo bulk sender requirements.
• Reputation. Aligned mail builds reputation for your domain. Unaligned mail partly relies on the platform's shared reputation, which you do not control.

How to remove "via"

Step 1: Find which service sent the message

Open the email in Gmail, click the three dots and choose "Show original". Look at:

• DKIM: 'PASS' with domain ... near the top.
• The d= value in the DKIM-Signature header.

If the domain shown is not yours, that service is the one to fix. The email header analyzer can parse pasted headers.

Step 2: Authenticate your domain in that service

Every major sending platform has a domain authentication or sender authentication page. It gives you DNS records, usually two or three CNAMEs or a TXT record with a DKIM public key. Add them at your DNS host and click verify in the platform.

If you send from Google Workspace or Microsoft 365 directly, make sure DKIM is turned on in the admin console; see Google Workspace DKIM setup or Microsoft 365 DKIM setup.

Step 3: Set a custom return-path if offered

This is optional for removing "via" but helps SPF align as well. Look for "custom return-path", "bounce domain" or "custom MAIL FROM". What is a return-path address explains what it does.

Step 4: Check DNS and send a test

Use the DKIM checker to confirm the record is published, then send a new test to Gmail. The "via" label should be gone, and "Show original" should show DKIM passing for your domain.

When "via" still shows

Situation	Likely reason
Records added but test still shows via	DNS not propagated yet, or platform not re-verified
Some emails show via, others do not	A second tool is still sending unauthenticated
From address uses a different domain than you authenticated	Authentication covers one domain; the From uses another
Mail is forwarded through a mailing list	The list re-sends and signs with its own domain

The DNS propagation checker shows whether new records are visible globally.

Audit every sender at once

Most companies have more tools sending as their domain than they realise. DMARC aggregate reports list every source using your domain and whether it aligns. The DMARC report analyzer turns them into a readable table, so you can fix each "via" source in one pass.

Where to look in common tools

The setting is usually under a name like "domain authentication", "sender authentication", "verified domains" or "custom DKIM".

Type of tool	Where the setting usually lives
Email marketing platform	Account or brand settings, under domains
CRM with email sending	Email settings or deliverability settings
Transactional email service	Sending domains or identities
Help desk	Channel or email settings, under the support address
Website or form plugin	SMTP settings; switch to an authenticated sending service

If a tool has no option to sign with your domain, consider sending its mail from a dedicated subdomain, or routing it through a service that does support custom DKIM.

Quick answers

• Is "via" the same as spam? No. It is a label about authentication, not a spam verdict, but it often accompanies alignment problems that do affect placement.
• Does Outlook show something similar? Outlook can show "on behalf of" or sender warnings in some cases, for similar reasons.
• Will removing "via" fix deliverability on its own? It fixes one signal. Volume, list quality and engagement still matter.

Authentication and clean lists work together

Removing "via" ties your mail clearly to your domain. That means bounces and complaints from your campaigns count directly against your domain too. Keep lists clean so that reputation stays healthy: upload a list on the verify page and you get 100 free email checks when you sign in with Google, no card.
