For many senders, deliverability troubleshooting starts with SPF, DKIM, DMARC, PTR, and complaint rate.
That is correct, but it is not the whole picture.
Google's current sender guidelines also call out display-name misuse and other misleading message elements as things that can hurt delivery to personal Gmail accounts. That includes fake reply patterns, recipient-name tricks, emojis used to imply verification, and display names that obscure who is actually sending the message.
In other words: even if your authentication is clean, Gmail does not want bulk mail that looks deceptive at first glance.
If you send mail to Gmail users, your display name should do one job only: clearly identify the sender.
The safe pattern is simple:
Examples of safer display names:
Example StoreExample Store ReceiptsExample AlertsExample SupportExamples Gmail explicitly treats as problematic or misleading:
Re: your accountMaria from Example when there is no real person-to-person relationshipJohn (2) to imitate an existing threadImportant Update ---------- From [Company Name]Google's Email sender guidelines now include a dedicated section on display names.
The important parts are very direct:
Google also says that misleading headers, display names, and other message elements can affect whether mail is delivered as expected. It further warns that senders who ignore these practices may not be considered for deliverability mitigations.
That last part matters operationally. Gmail is not framing this as a cosmetic preference. It is part of sender quality and trust.
Some senders try to raise open rates by making a campaign look like an existing conversation.
Common patterns include:
Re: or Fwd: when the message is not an actual reply or forwardAlex (2) or [1] New MessageGoogle explicitly says not to send messages with subject lines starting with Re: or Fwd: unless the messages are actual replies or forwards. The same anti-deception logic appears in its display-name guidance, which says the display name should not imply a message reply or threaded conversation.
Why this hurts deliverability:
This is the same broader theme Google applies elsewhere in the guidelines: message headers and content should be accurate, not misleading or deceptive.
This is not about all emoji usage everywhere in email body content. The Gmail-specific problem is using emojis or other non-standard characters in sender identity fields to influence trust or imitate a visual badge.
Google's wording is precise: do not use emojis or other non-standard characters to imitate graphic elements with the intent to deceive or influence recipients. It gives the example of using emojis or images next to display names or brand names to imply that the sender has been verified.
That means these patterns are especially risky:
Example Bank checkmarkExample Alerts warning-iconExample Support lock-iconEven when the sender thinks the emoji is "just branding," the receiver-side concern is simple: does this make the sender identity look more trusted, more urgent, or more official than it really is?
If the answer might be yes, remove it.
Many admins hear "misleading sender identity" and think only about SPF, DKIM, and DMARC failures.
Those controls matter, but Google's guidance here is broader.
You can authenticate perfectly and still create a sender-identity problem if the visible name misrepresents who the message is from.
Examples:
Google even calls out deceptive display-name practices such as using an @gmail.com domain as the display name for bulk email, using the recipient's name in the display name, and using characters that imply threaded conversation.
So the operational rule is:
Authentication proves technical authorization. The display name still needs to prove human clarity.
Google does not publish a formula that says "one emoji equals one spam-folder point."
But its documentation makes the likely mechanism clear enough:
This fits Google's broader sender model:
That is why a display-name cleanup can improve results even when DNS authentication is already correct. You are removing a recipient-trust problem, not just a protocol problem.
Here are practical rewrites for common Gmail-risky patterns.

Example RenewalsExample Customer CareExample MembershipIf you want personalization, keep it inside the message body where the context is obvious.
Avoid:
checkmark Example Paywarning Example Securitystar Verified ExampleSafer alternatives:
Example PayExample SecurityExample Account AlertsGoogle's sender guidelines also recommend that messages of the same category use the same From: address.
That principle works well for display names too.
For example:
Example Receipts <sales@example.com>Example Alerts <alert@example.com>Example Deals <deals@example.com>This consistency helps recipients recognize the mail faster and reduces the chance that a legitimate campaign looks like a fresh attempt to bypass attention filters.
It also makes complaint analysis easier. If one sender identity starts attracting negative feedback, you can isolate that stream faster in your campaign system and in Gmail Postmaster Tools.
Review every active sender identity and ask:
Re:, Fwd:, counters, or fake-thread signals?If any answer is no, fix the sender identity before the next campaign launch.
After changing risky display names, monitor:
Do not expect an instant magic jump. But if your previous naming style was pushing users toward distrust, removing deceptive patterns can reduce complaint pressure and help the stream look more legitimate to Gmail.
If you are also working through broader Gmail compliance work, these related guides can help:
For Gmail deliverability, the display name is not a throwaway marketing field.
It is part of sender identity.
If it looks like a fake reply, a fake badge, a fake relationship, or a fake sender, Google has already told you not to do it. Keep the visible sender name plain, honest, and recognizable, and let your real reputation do the work.
