The vast majority of signatures we face in our daily work are “wet” - meaning they’re physical and hand-written. 

Sending and signing physical documents has slowed down businesses worldwide for decades. But modern technology has now offered a new, digital solution: the eSignature.

With eSignatures, the average time it takes a business to sign a document can be shortened from 5 days to 37 minutes!

What is a Wet Signature? How does it compare to digital signatures? What are the primary advantages of an eSignature? How can you switch from wet signatures to faster eSignatures?

At SignHouse, we believe that signing documents and contracts should be as straightforward as possible. We want to help you learn more about the world of electronic signatures, and what they mean going forward for you! 

In this article, we'll discuss what wet signatures are. We’ll also explore the difference between a wet signature and an eSignature, and why digital is truly the future.

What is a Wet Signature?

A wet signature is simply a traditional ink signature. Labelled a “wet” signature due to the ‘wetness’ of ink, it’s usually a name or mark signed with a pen on paper. Here’s a wet signature from Martin Luther King, Jr.

The term “wet signature'' predates the digital era, with some usage of the term recorded in the 1800s. 

Why do people use wet signatures? Wet signatures have always been the predominant way to sign documents. 

While the first ever form of signature — the seal — dates back to the Sumerians (4500 B.C. - 1900 B.C.), the primary reason why wet signatures have been the gold standard of authentication is due to the permanence of ink.

Ink to paper is permanent. While it can be tampered with and forged — we’ll get onto the flaws with wet signatures later on — a physical wet signature is still better than no signature or a seal that can be melted away and replaced.

What’s the difference between Wet Signatures and eSignatures?

There are many core differences between wet signatures and eSignatures. Let’s discuss why a business would choose a digital eSignature over a traditional wet one.

Digital vs. Physical

Of course, the glaring difference is that wet signatures are physical, whereas eSignatures are digital. Rather than being ink to paper, an eSignature is made of algorithms and code.

The digital nature of eSignatures can often be a barrier to entry for some businesses. Some people think that digital signatures aren’t as legitimate or legally binding - but this just isn’t the case. 

eSignatures will hold up in any court of law - just like any other signed document. In some cases, eSignatures can be safer! The metadata attached to digital signatures is harder to forge than real signatures and witnesses.


In regards to security, both methods have unique advantages and disadvantages. But there’s one major difference between the two.

A physically signed document can be destroyed and physically tampered with. An electronically signed document can’t ever really be destroyed. This is especially true if you’re backing up your documents properly, and following good security practices.

Of course, the looming threat of hackers is always the boogeyman of digital security. That said, Verizon found that nearly 95% of all espionage attacks are the result of phishing attacks — attacks where a scam email is created to bait you into entering personal information to be stolen.

This means that as long as you stay vigilant and ensure to follow the correct security procedures, the risk of your electronic signature being breached is nil.

Companies like SignHouse also use data such as your IP address and two-factor authentication to keep your signature away from any bad faith actors.

In other words, your signature will always be safe away from fraud and forgery attempts, as nobody will be able to log in to your account to sign documents without your permission.


There is a vast difference in cost between an eSignature and a wet signature. To sign a document physically, you usually need to print it out and scan it.

This means you’ll need access to a printer, which — with ink, power and purchasing costs — can get very expensive. 

For larger businesses, dedicating IT resources to fixing printer hardware can also cost a lot.

Every year, US businesses throw away $8 billion in handling and signing paper documents. According to a 2020 study by LunarPen, businesses can save as much as $20 for each document signed digitally

An eSignature has minimal costs involved. Especially with services that offer stellar free plans like SignHouse, you often don’t have to pay anything extra to be able to use them. And, the premium plans for most services are still far cheaper than having to buy and maintain a printer.


Having to find a pen to sign a contract can take minutes out of your day, let alone the hassle of having to print and scan the document. Do you really want to spend so much time on such a mundane task?

Having to carry paper documents over to a client who lives across the city can just be a nightmare. Online documents and eSignatures allow you to simply just bring a phone or tablet along with you, and mean that you can receive and sign on the go with a few simple clicks!

We found that businesses looking to send out quick non-disclosure agreements (NDAs) find eSignatures the most straightforward way of achieving this. All you’ll need to do is create a digital document - perhaps using a template like ours - and then send the contract off to the other party. 

SignHouse allows you to simply just drag-and-drop your eSignature into any document on any device! Rather than wasting your time, our service just works with no hassle and no stress!


Leading on from this, eSignatures are just far more efficient than wet signatures. Rather than having to print and sign, then scan, you can easily just drag and drop your electronic signature into documents using a service like SignHouse

No fuss, no weird programs to download — SignHouse works in your browser, and only requires a few clicks!

Using eSignatures also makes correspondence much quicker. Studies show that eSignatures can lead to an 85% rise in efficiency and an 80% reduction in the errors made when signing documents.

Rather than having to go through that whole process of printing and signing, you can just do everything with a few simple clicks. This means that naturally, everything gets done quicker! 

In industries like real estate, quick and efficient signing of contracts is key to quickly completing deals. Sending documents like a commercial lease or tenancy agreement for signing has never been easier than with SignHouse.

Some of our customers use SignHouse to get a freelancer contract signed, helping avoid any delays in getting projects started!

So, there’s no wonder why businesses are rapidly switching to eSignatures, with so many added workflow benefits!

Is an eSignature ‘Real’?

People often question the legitimacy of eSignatures, so wet signatures are often favored. But eSignature has been legally recognised for a long time. In 2000, the ESIGN act allowed Americans to use electronic signatures and have them be legally recognized. 

eSignature providers such as SignHouse have developed robust security measures into their platforms. These security features - including certificates of completion and tamper-proof digital seals - make eSignatures a safe and trustworthy form of authentication.

Consequently, companies have been taking eSignatures more seriously. This has led to eSignatures quickly becoming the industry standard.

So, yes. eSignatures are real and legitimate for legally binding documents.

Are your electronic signatures legal?

Our signatures are 100% legally binding, as SignHouse is built around US and International Laws concerning digital signatures. SignHouse eSignatures are on par with paper signatures, from a legal point of view!

Signing papers digitally started being equal to physical, handwritten signatures in the U.S. eSignature Act of 2000 (U.S. Federal Act) + the Uniform Electronic Transaction Act (UETA). As a consequence, laws in other countries have followed suit. SignHouse is built around these laws.

Can a signature be typed?

Your signature 100% works and is 100% legal if it's typed, if you're using an electronic signature software!

Why? It's validity is given by other factors: 

  • As per the eSignature (2000) and UETA (2000) Acts passed by the US Government, alongside other requirements (explained in-depth by us here), one of them is this: “Attribution. The signature has to be uniquely identified to the signee and only linked to them”
  • Using an electronic signature software such as SignHouse automatically handles that, as such apps easily attribute signatures with identifiable details (e.g. account information, location, IP, etc)
  • Another requirement for a digital signature to be valid: “Retention. The documents must be stored for future reference, available to be viewed, reviewed, edited, etc. by both parties”
  • SignHouse takes care of this aspect as well.

Therefore, typing your signature makes it valid, due to the aspects that an eSignature software handles for you.

Can a signature be your initials?

Yes, it absolutely could be! Why: your electronic signature is not defined by how it looks. It could even be a glyph.

Your signature's validity is given by other aspects, as explained in this article of ours:

  • As per the eSignature (2000) and UETA (2000) Acts passed by the US Government, alongside other requirements (explained in-depth by us here), one of them is this: “Attribution. The signature has to be uniquely identified to the signee and only linked to them”
  • Using an electronic signature software such as SignHouse automatically handles that, as such apps easily attribute signatures with identifiable details (e.g. account information, location, IP, etc)
  • Another requirement for a digital signature to be valid: “Retention. The documents must be stored for future reference, available to be viewed, reviewed, edited, etc. by both parties”
  • SignHouse takes care of this aspect as well.

So yes, your signature can be your initials!
