Here is a message that goes out of Indian companies several million times a day:
Sounds good, will send the deck by Thursday.
Thanks,
RahulNothing is wrong with it. It's polite, it's clear, and the recipient knows exactly what happens next.
It also contains no company name, no phone number, no way to look Rahul up, and no indication of which of the four Rahuls the recipient has met this quarter is writing. If someone forwards it to a colleague — which is what happens to most business email — the colleague receives a message from a stranger.
"Thanks, Rahul" is a sign-off. It closes the message. A signature is a different object with a different job, and the confusion between the two is why so many otherwise well-run companies send email that quietly undersells them.
This post explains what a branded email signature actually is, breaks it down layer by layer, and shows the difference with a worked before-and-after.
Sign-off, signature, disclaimer: three different things
Worth separating these first, because they get used interchangeably and they aren't the same.
A sign-off is the closing courtesy. "Best regards." "Thanks." "Warmly." It belongs to the message — it changes depending on who you're writing to and what you're saying. You'd close differently to a client and to your co-founder.
A signature is the fixed block that follows. It doesn't change with the message, because it isn't about the message. It's about you and the company you represent. It goes out identically whether you're sending a proposal or confirming a meeting.
A disclaimer is the legal notice some companies append below the signature — confidentiality language, and in India, statutory particulars. Related, but a separate component with a separate purpose.
Most people have the first. Fewer have the second. Almost nobody has thought carefully about the third.
What a signature is actually for
Three jobs, in order of how often people think about them — which is roughly the reverse of how much they matter.
It identifies you. Not just your name, but your role and your organisation. The recipient may have met forty people this month. They may be forwarding your email to someone who has never met you at all. A signature answers "who is this?" without anyone having to ask.
It makes you reachable. Email is not always the right channel. Sometimes the recipient needs to call, or to check your website before a meeting, or to find your office. If they have to search their inbox for an older thread to find your number, you have introduced friction into your own deal.
It carries your brand. This is the one that gets underestimated, and the maths is worth sitting with. Radicati Group data puts the average office worker at roughly 40 emails sent per day. Even if only a third of those go outside your company, a fifteen-person team is putting something in front of external recipients tens of thousands of times a year.
There is almost nothing else your company produces at that volume. Your website gets a fraction of those views. Your paid campaigns, if you run any, cost real money per impression. The signature is free, it's already happening, and for most companies it's carrying nothing.
The anatomy, layer by layer
A branded signature isn't a list of fields. It's five layers stacked, each doing a different job. Understanding them as layers is what lets you decide what to cut, because you can ask "which layer does this serve?" rather than "does this look nice?"
Layer 1 — Identity
Who you are and what you do.
- Full name. As you actually write it. If your name is
S. Venkatesh, that initial goes in front and is not a middle initial to be relocated. - Job title. The one on record with HR, not an aspirational version. If a recipient forwards your email internally, your title tells their colleague whether you're the right person to be talking to.
- Company name. Non-negotiable. The single most common failure in the "Thanks, Rahul" pattern is that the company vanishes entirely.
Optionally: department or team, if your company is large enough that "Sales" and "Partnerships" are meaningfully different doors. Pronouns, if your team wants them.
Layer 2 — Contact
How someone reaches you when email isn't right.
- Phone. Formatted for humans:
+91 98765 43210. Label it if you list more than one —M:andT:removes all ambiguity. - Email. Yes, even though they're reading your email. It survives forwarding, printing, and screenshots, and it lets someone copy your address without digging through headers.
- Website. One URL, the main one.
The discipline here is restraint. Every additional channel dilutes the ones that matter. A signature listing mobile, landline, alternate email, WhatsApp, Telegram, Skype and a fax number is not more reachable — it's harder to act on.
Layer 3 — Brand
The layer that makes it branded rather than merely informative.
This is what separates a signature from a business card typed out in plain text. It has four components:
- Logo. A real image file, hosted properly, sized for email — around 180px wide is a sensible ceiling. With alt text, always, because image blocking is routine and
alt="Meridian Labs"is infinitely better than a broken-image icon. - Colour. Your brand colour, used once — usually on the name. One accent is a design decision; four is a ransom note.
- Typography. A websafe stack: Arial, Helvetica, sans-serif. Your custom brand font will not load in email clients and will silently fall back to something you didn't choose. If that font is essential to your identity, put it in the logo image where it renders as pixels.
- Hierarchy and space. Name largest. Title and company a step down. Contact details smaller. Legal footer smallest. Whitespace between the groups. This is what makes a signature scannable in the half-second anyone spends on it.
Layer 4 — Compliance
The layer most Indian companies skip.
Section 12(3)(c) of the Companies Act, 2013 requires every company to carry its name, registered office address, and Corporate Identity Number on business letters and official publications — and the settled professional reading treats external business email as falling within that. Section 12(8) prices non-compliance at ₹1,000 per day of continuing default, up to ₹1,00,000, applying to the company and to officers in default separately.
So for an Indian private limited company, the compliance layer is:
- Company legal name, as registered
- CIN
- Registered office address (which may not be where you sit)
Set it at 10–11px in a muted grey, below a visual break. It's there to satisfy a disclosure obligation, not to be read.
One correction while we're here: your GSTIN is not required in email. GST law asks for it on tax invoices and on the name board at your place of business. Include it if your B2B customers keep asking, and leave it out otherwise.
(We've written a full breakdown of the Indian compliance position separately, including where the common advice goes wrong.)
Layer 5 — Action
Optional, role-specific, and the layer most often abused.
A booking link for sales. A support address and published hours for customer success. A campaign banner, if marketing owns it and there's an actual campaign.
The rule: this layer earns its place or it doesn't exist. A booking link in a sales rep's signature removes a scheduling round-trip from every deal — clearly worth it. A "Follow us on Instagram" icon in an engineer's signature serves nobody.
Before and after
Same person, same message.
Before
Sounds good, will send the deck by Thursday.
Thanks,
Rahul
What the recipient can do with this: reply. That's the complete list.
After
Sounds good, will send the deck by Thursday.
Best,
Rahul Menon

What changed:
- The sign-off stayed. "Best" still belongs to the message. The signature sits below it.
- Full name and role mean a forwarded copy still makes sense to a stranger.
- The company exists now, in a way it didn't before.
- A phone number means a recipient with an urgent question doesn't have to wait for email.
- The logo does the brand work, on every send, for free.
- The compliance footer discharges a statutory obligation that was previously being ignored on every external email the company sent.
The message took the same three seconds to write. The signature was configured once.
What disqualifies a signature from being "branded"
Four common patterns that look like signatures but aren't doing the job.
The name-only. "Thanks, Rahul." Discussed above. It's a sign-off doing a signature's work, and failing.
The wall of text. Nine lines of contact details, a quote about persistence, an environmental notice asking you not to print, a 200-word confidentiality disclaimer, and six social icons. Everything is present and nothing is legible. More information is not more communication.
The single image. A designer produces something beautiful as one PNG. It looks perfect right up until the recipient's email client blocks images — which happens routinely, by default, for privacy reasons — and the entire signature becomes one broken rectangle. Name, phone, company: all gone. Images carry the logo. Nothing load-bearing lives inside a picture.
The generator advert. Free signature tools frequently append their own branding — "Create your signature with X." You have turned your company's most-sent asset into someone else's marketing channel.
The bit that's harder than it looks
Everything above describes one signature. Building it takes an afternoon.
The difficulty arrives at the fifteenth one.
A new hire has no idea what your signature should look like, so they do the reasonable thing: copy a colleague's email and edit the details. If that colleague's signature is two years out of date, the new hire inherits the old logo, the old office address, and a phone extension that was disconnected in 2024. Then the next hire copies them.
Meanwhile someone rebuilds their signature after a laptop refresh and drops the compliance footer because it looked like clutter. Someone's mobile signature still says "Sent from my iPhone" because mobile is configured separately and nobody mentioned it. Your registered office changes and twenty-two signatures quietly become non-compliant, each accruing a daily default nobody is tracking.
None of this is anyone's fault. It's what happens when a company-wide standard is enforced by individual memory across fifteen machines, and it's why the manual approach stops working somewhere around ten people.
The structural fix is to stop asking people to remember: one template, deployed centrally, where the correct signature isn't something each person applies but something they can't avoid. That's what we're building at Signforus — flat pricing rather than per seat, aimed at Indian teams of five to fifty. We're in early access now.
But start with the definition, because you can't deploy a standard you haven't specified. Write down your five layers. Decide what's in each one. Then worry about how it gets to everybody.
And in the meantime — put the company name in. That one's free.
