How to create your professional email signature?

1 - Adapt your content

The shorter your e-mail signature, the greater its impact. Signatures that are too long generally fail to attract attention. Bear in mind that an e-mail signature is first and foremost a signature, so it needs to be concise and clear.

👉 We advise you not to exceed 3 or 4 lines of text.

So, for optimal, appropriate content, you should include the following elements in your e-mail signature:

  • First and last name,
  • Position,
  • Company name, logo and link to website,
  • Telephone number and/or postal address

    (Inserting a photo is optional but recommended).

Now that you've got the essentials for creating the perfect signature, you've got one or two lines left to personalize your content. For example, we recommend :

  • Insert your social networks, in the form of logos, to save space. This can be a real communication lever. For this reason, you should only include in your content the social networks on which you are active.
  • Include a "Call to action" (CTA). It can link to the latest article you've posted, the platform on which you manage your appointments, the link on which you offer visitors quotes... This can considerably enhance your content strategy.
  • Highlight relevant certifications or achievements, such as an SEO certification, award or ranking. This will promote your expert status and credibility as a professional.

2 - Adopt an HTML format

It's one thing to offer relevant, attractive content; it's quite another to implement a clean, optimal layout! The question of readability must be given just as high a priority as visuals and content.

Not all your recipients have the same e-mail system. As a result, not all images are displayed in the same way. It's therefore advisable to present your content in text format and not 100% image.

👉 Give preference to HTML format. It guarantees optimal display for all mailboxes, and is highly adjustable. You can add images or adjust your text at any time.

If you're not familiar with HTML, don't worry! There are plenty of tools available to help you create your HTML e-mail signature easily and optimally!

We'll introduce them a little further on in this article.

3 - Make sure your e-mail signature is responsive

It's also important to adapt your design and content to all digital formats. An e-mail signature that doesn't display properly on cell phones or tablets can be problematic. Your content must therefore be " Web adaptive" and " Responsive Design". In other words, your content must be adaptable and attractive on any digital device.

The main points you need to pay particular attention to are :

  • Font size

    Minimum 10px

  • Image size
    → Width between 320 and 600 px
    → Height between 90 and 150 px

  • Overall mail signature size
    600px wide and 250px high

  • Weight
    Maximum 120Kb

  • Dimensions of clickable areas
    They must be large enough to allow the user to click easily.

  • The distance between clickable elements
    They must be far enough apart to avoid confusion.

4 - Adapt your signature to your teams

By now we know that a beautiful, professional email signature makes you more professional in the eyes of your contacts. But if the customer is communicating with several team members, different signatures will lose you credibility .

A professional email signature must therefore be corporate and respect the company's graphic charter. You must therefore harmonize and unify your collaborators' signatures.

However, harmonizing your e-mail signatures doesn't necessarily mean that they're all identical. Each department or employee can personalize their CTA and/or end-of-line elements. For example

  • the sales department can add a CTA to book an appointment or to read the latest white paper;
  • the marketing department can add a link to the latest content it has created (article, infographic, etc.);
  • the human resources department can add a link to its recruitment platform.
