You’ve seen it a thousand times in your own inbox. You get an email, look at the sender, and immediately hit delete without even reading the subject line. Most people think the subject line is the most important part of an email, but they’re wrong. Honestly, it's the S From Name that does the heavy lifting.
If the "From Name" looks suspicious, robotic, or just plain weird, that email is dead on arrival.
It’s the first thing we check. Before we decide if a message is worth our precious time, we subconsciously ask: Do I know this person? If the answer is no, or if the name feels like a marketing bot trying too hard to be my friend, the relationship ends right there. Getting the S From Name right is basically the digital equivalent of a firm handshake. If it's limp or creepy, you're out.
What is the S From Name anyway?
In technical terms, the "From Name" is the display name associated with an email address. It’s the human-readable part that sits next to the actual email address in an inbox. While the address might be news@company.com, the From Name is what you actually see—like "Company News" or "Sarah from Company."
It sounds simple. It isn't.
Most email clients, especially on mobile, prioritize this name over everything else. On an iPhone or a Pixel, the S From Name takes up the most screen real estate in the notification tray. If you mess this up, you aren't just losing opens; you're actively training spam filters to hate you. When users don't recognize a sender, they don't just ignore it—they report it.

The psychology of recognition
We are wired to look for people, not brands. Think about it. When you see a name like "John Smith," your brain processes it differently than when you see "The Discount Warehouse."
The "S" in the context of sender names often refers to the Sender identity in programmatic environments or specific CRM platforms like Salesforce or HubSpot. These systems allow you to dynamically swap out names based on who is receiving the email. But just because you can automate a name doesn't mean you should make it look automated.
The big mistake: Testing things that don't matter
Marketers spend hours A/B testing subject lines. They’ll argue over whether to use an emoji or a question mark. Meanwhile, the S From Name stays as a boring, static company name for five years straight.
Huge mistake.
Data from groups like Pinpointe and Campaign Monitor suggests that the sender name is the single most influential factor in whether an email gets opened. People trust people. They don't necessarily trust "Marketing Department." If you want to see a real jump in engagement, stop tweaking your "50% off" subject line and start looking at how you're identifying yourself.
Why "The Team" is killing your conversion
Don't ever use "The [Company] Team." Just don't. It’s vague, it’s lazy, and it feels like a shield. When I see an email from "The Support Team," I assume I’m about to talk to a chatbot or a tiered ticketing system that doesn't care about my problem.
If a real human wrote the email, use their name. "Jane at TechCorp" beats "TechCorp Support" every single day of the week. It’s personal. It’s direct. It feels like a 1-to-1 conversation, which is exactly what email was designed for before it got hijacked by mass newsletters.
Technical hurdles you can't ignore
There is a dark side to the S From Name. It’s called "Display Name Spoofing."
This is a common tactic used in phishing attacks. A hacker will set their S From Name to "CEO Name" or "IT Help Desk," even though the actual email address is scammer123@random-domain.com. Because most people only look at the display name on their phones, they get fooled.
Because of this, email providers like Gmail and Outlook are getting much stricter. If your From Name doesn't align with your sending reputation or your DMARC records, you might find yourself in the "Promotions" tab—or worse, the "Spam" folder.
Brand Indicators for Message Identification (BIMI)
If you’re serious about your S From Name, you need to look into BIMI. This is a technical standard that allows you to display your brand’s logo next to your name in the inbox. It’s like a "verified" checkmark for email.
It requires you to have strong security protocols (like VMC and DMARC enforcement) in place. But once it’s set up? Your sender identity becomes unmissable. It’s the ultimate way to stand out in a crowded inbox where everyone else is just a gray circle with an initial in it.
The "Person + Company" formula
There is a sweet spot for the S From Name.
If you just use a person's name, like "Alex," people might get confused if they don't know who Alex is. They might think it's a personal email, realize it’s a marketing pitch, and feel tricked. That's a fast track to an unsubscribe.
If you just use the company name, like "Acme Corp," it feels cold.

The winner? [First Name] from [Company].
- "Sarah from Peak Design"
- "Marcus at Spotify"
- "Leo | Ghostwriter"
This format provides immediate context. It tells the reader who is talking and why they are talking. It creates a sense of accountability. Honestly, it’s just polite. You wouldn't walk up to someone in a bar and say "Acme Corp is having a sale." You’d say your name first.
Mobile vs. Desktop: The truncation problem
You have to remember that screen space is a luxury.
On a mobile device, you usually only get about 20 to 25 characters for your S From Name before it gets cut off with those annoying little dots (...). If your company name is "The International Association of Professional Underwater Basket Weavers," your name is going to look like "The International Assoc..."
That tells the reader nothing.
Be concise. If your brand name is long, find a way to shorten it for the sender field. Prioritize the most important words. If you're using the Person + Company format, make sure the person's name is first, because that’s the part that builds the connection.
Consistency is actually a strategy
Don't change your S From Name every week.
People are creatures of habit. If they get used to seeing "David @ Substack" in their inbox every Tuesday morning, they’ll start looking for it. If David suddenly changes it to "Substack Weekly Insights," the mental connection is broken. The reader has to work harder to figure out who you are, and in the world of email, if you make the reader work, you lose.
Pick a format and stick with it for at least a quarter. Monitor your open rates. If you decide to rebrand or change the sender, do it gradually or announce it.
The exception to the rule
There is one time you should change it: segmentation.
If you’re sending a transactional email (like a receipt), the S From Name should probably be the company name. People expect a receipt to come from a brand. If you’re sending a thought-leadership newsletter, it should come from an individual. Using different sender names for different types of content helps the user categorize your emails without even thinking about it.
Authenticity can't be faked (for long)
If you use a fake name in your S From Name, people will eventually find out.

I’ve seen companies use "fake" personas—essentially a fictional character who "writes" the emails. It works for a while, but it feels hollow. If someone replies to that email and gets a canned response from a different department, the illusion is shattered.
Use real people. Use real names. If your CEO doesn't have time to write emails, have the person who actually wrote them use their own name. People appreciate transparency more than a polished, corporate facade.
Practical steps to fix your Sender Identity
It's time to stop neglecting the most visible part of your email strategy. You can have the best copy in the world, but it doesn't matter if no one opens the message.
First, audit your current sent folder. Look at your emails on your phone. Does the name get cut off? Does it look like a robot sent it? Does it match the tone of the content inside?
- Verify your records. Make sure your SPF, DKIM, and DMARC are set up correctly. This ensures your S From Name actually makes it to the inbox.
- Shorten the string. Keep your display name under 20 characters to avoid mobile truncation.
- Try the "Person + Company" format. Test "Name from Brand" against just "Brand." Nine times out of ten, the human element wins.
- Clean your list. If people haven't opened an email from your "From Name" in six months, they aren't going to start now. Remove them. It protects your reputation.
- Check for "No-Reply." If your S From Name is "No-Reply," you are literally telling your customers that you don't want to hear from them. Change it to a monitored address and a real name immediately.
Email isn't about broadcasting; it's about building a bridge. That bridge starts with a name. Make sure yours is one people actually want to see.
