With digital signature software, you can sign documents online and create them. These are legally binding documents, too. They’re as good as having a hard copy with a handwritten signature.

Some of the most popular online signature software options available include:

  • Signaturely
  • DocuSign
  • EverSign
  • DocHub

DocuSign is an electronic signature tool

DocuSign is an electronic signature tool that allows you to sign documents online. You can add your e-signature to contracts or documents you receive via email. However, it’s not free like Signaturely. Here are some affordable DocuSign competitors.

Signaturely is a free, easy-to-use electronic signature software designed to simplify signing digital documents. With it, you’ll be able to sign any emails. It’s a perfect solution for anyone looking to streamline their digital workflow.

Signing an email document is easy with Signaturely. Here’s how to do it:

Step 1. Open Your Signaturely Account

Step 2. Select Who Needs to Sign Your Email Document

Once logged in, go to the Sign tab at the top of the left sidebar. Once on that page, you’ll have three options to choose from:

  • Only Me: if you only need to add your own signature to the document.
  • Me & Others: if you need to add your and other individuals’ signatures to the document.
  • Only Others: if you only need to add other individuals’ signatures to the document.

Select the one that best fits your needs. 

Step 3. Complete Your Document For Signing

Prepare your document for signing

Once you’ve selected who needs to sign, you’ll arrive at a document preparation page. On this page, you can upload your email document, assuming you had previously downloaded it.

Upload your files

After uploading the document, you can sign it by clicking on Fill Out & Sign.

Fill out and sign the document

An editor will load, allowing you to add your signature to your email document.

Add your signature on the document

Once you’ve added all the signatures and information necessary, press the Send button in the top right corner. Doing so will send the completed document to your inbox. You can also download it when this pop-up appears: 

Send your document

Congratulations! You’ve successfully used Signaturely to sign your email document.

You can continue to use Signaturely to add a signature to your emails, making them legally signed documents. It’s entirely free. With Signaturely, you can also send up to three monthly signature requests

You can upgrade your plan if you require more than three signature requests. The “Personal” plan costs $20 per month, allowing you to make unlimited signature requests and create a template.

Overall, Signaturely is one of the best e-signature tools available. It’s worth using because it saves time and effort in digitizing your document signing workflows. You won’t need to print documents and get physical signatures. You can sign emails digitally.  

2. Use the Built-In Signature Feature of Your Email Provider

Another way to sign a document is with the built-in feature available with most email service providers. All email services include it, from Gmail, Outlook, and Yahoo to business-specific platforms like Mailchimp.

They allow you to create and save a signature that you can quickly add to your email documents. You don’t even have to leave your email inbox/suite to do so. Head over to your settings page, create a signature, and add it to your documents.


  • No need to leave your email inbox/suite to sign a document
  • The fact it’s built-in makes it easy to use
  • Saves time by simplifying the digital signing workflow
  • Free feature


  • Signatures not very high in quality
  • Signed documents are hard to track
  • Much harder to maintain a history of your document-signing activities
  • No extra features that other options like e-signature apps offer
  • Can’t request signatures from others
