Dos Of Email Signature Marketing- Email Signature Best Practices

1. Lay out a good email signature design

This is a hallmark of all good email signatures.A maximum of 7 lines – that’s the ideal professional business email signature format. All effective email signature templates generally contain your key contact details, social media icons, and advertising message. However, one of the most important things to consider is the design and layout of your HTML email signature template; make sure it goes well with the type of industry you are in. You can let your creative juices flow here but don’t lose sight of professionalism in the process. After all, the ideal signature block examples are those that align to a fault with their brand aesthetic and look. 

  • Your key contact details should always be in the same color as that of the email body text to ensure consistency.
  • Links can be in different colors.
  • Maintain a fixed font type and size throughout the mail. You can experiment with the font but it’s better to stick to the web-safe fonts, so as to make sure they are legible across devices and email clients.

2. Link Email Recipients to Your Website and Blog

Every email sent from your company should have a professional email signature accompanied by a link to your website. Though this rule is pretty fundamental, you’d be surprised to know just how few companies actually stick to it. You need to take advantage of the fact that your recipients are already online.

By providing a link to your website in your customized email templates, you are essentially giving them the option to re-engage and stay connected with you. Links can be of two types: Text links and Image links. You could just give a link to the blog home page or create a direct link to your latest blog post. Take a look at a few email signature examples, such as the ones highlighted below, to get a better idea.

You could also link to your app on the App Store or Google Play Store from the signature. Create a QR Code for shortening the path to downloading an app from desktop to mobile.

3. Connect with them through social media

Social media is everywhere, and so it should be on your professional email signatures too.

Now, this might sound very obvious, but well, not many businesses take it seriously. So, we’re going to spell it out in detail for you. Different countries have different laws. Hence, depending on where you run your business, it is mandatory to add a few details about your company in your email signature. For instance, as per the laws of the Netherlands, you have to include details like your company name, registration number, registry location, registered office, etc. Thereby, it is best to consult your legal representative to find out more.

7 Don’ts Of Email Signature Marketing

1. Do not Go Overboard

You need not go overboard by including every single detail and contact information in your HTML signature. The worst personal email signature examples are those that contain a surplus of irrelevant content in them. Only add contact information that is necessary and regularly used. Adding multiple phone numbers, email addresses, websites, and social media networks, might appear confusing and instantly put off your audience. The most creative email signatures out there have simplicity at their cores. Here is an HTML email example showing what you should never do in your signature.

2. Avoid Multiple Fonts

Although you can experiment with colors and fonts, avoid using more than 2-3 different ones if you really want your professional or personal email signature to look stylish. The fonts, colors, and design – all put together in the following HTML email signature should be strictly avoided for it can end up in your signature looking visually jarring.

3. Avoid Using Images for Signature

Using an image as your signature in an HTML email is a big NO. With many devices and email clients having default settings that block images, an email signature that is in an image format will not be visible to all. Also, not hosting images in your signature on a web server can turn against you. It is good to have ALT-TEXT as a fallback option.

4. Avoid Personal Quotes

Personal quotes in a business email signature can be a turn-off. Avoid them unless you are a writer or you have a mighty good reason to do so. In most cases, they can tend to rob you off your credibility. Besides, tooting your own horn isn’t very professional, is it?

5. Irrelevant Links

Irrelevant links in an email signature can be catastrophic. Even though you might want to add a link to your blog, make sure the blog is not too old and the content is relevant to the person receiving it. Remember that an email signature is a place where you’re telling your recipients about yourself and your brand or business. You need not overpopulate that space by including links to blogs or other resources; that is something you should ideally keep for your newsletters and other communications.

6. Minimal Use of Images

Signatures with more than two primary images are not going to take you anywhere. Your email recipient might get miffed because the download is costing him money. So, stick to a maximum of two images (if at all you have to use images), ideally with a length and width of 250px.

7. Disclaimers

Doing away with long disclaimers is one of the most fundamental best practices to keep in mind when you sit down to create HTML signatures. Just add a few lines and then, if the need be, and include a link to a detailed version. The disclaimer in the image below is an apt sized one:
