What is an email signature? 📧

Are you wondering what exactly is an email signature? It's simply a block of text, images, and links that place you at the bottom of your emails. Basically, it's like a virtual business card that is displayed with each email sent!

Generally, it contains the contact details of the sender, who signs the message, and thus attests to his identity. This information generally includes name, position, company name, company name, address, telephone number, and email address. This information allows your contacts to quickly identify you and contact you if necessary.

☝️ But be careful, an email signature is much more than just contact information! It is a real communication and marketing tool.

With a well-thought-out signature, you can :

• Enhance your brand image by including your logo and colors, like on a neat business card
• Generate qualified traffic to your website or social networks in one click
• Highlight your latest content (blog articles, white papers, webinars...) directly in the inboxes of your customers and prospects
• Promote Special Offers, Great Deals, or Events You Can't Miss
• Facilitate the interaction and commitment of your interlocutors by a simple action, such as making an appointment, by inviting them to contact you or follow you easily
• Sharing legal information, always in a professional manner

In short, the email signature offers you valuable space to get key messages across. Systematically and on a large scale. This is an opportunity to deliver targeted and relevant content in each email exchange. It's like automatically distributing a personalized business card, accompanied by a tailor-made message, to each of your contacts! Well used, it becomes a powerful lever to improve your reputation, generate leads and strengthen trust and relationships.

So in summary, remember this: email signature to communicate, electronic signature to sign a document. Easy, right? 😉

Without a dedicated tool, the door is open to inconsistencies, obsolete information, non-compliance with the graphic charter...

The Best Practice Guide for a Professional Email Signature

A well-thought-out email signature makes a good impression and encourages the engagement of your contacts. Here are some tips to optimize your signature and achieve your goals:

Step 1: Include the essentials

• Your name and position (let us know who you are!)
• The name of your company (let us know where you come from/who you represent!)
• Your contact details (email, phone, website) so that we can easily reach you

Step 2: Add a personal touch

• A Professional and Smiling Photo of You (to Humanize and Create a Link)
• Your slogan or business philosophy (to affirm your brand identity)
• Links to your relevant and active social profiles (to encourage interaction)

Step 3: Foster Commitment

• A clear call to action (CTA) that is in line with your goals (to encourage action)
• A link to subscribe to your newsletter or download a resource (to nourish the relationship)
• An invitation to a special event or promotion (to create a sense of urgency)

Step 4: Take care of the design

• Choose colors in line with your graphic charter (2 colors max to stay professional, and focus attention on the message)
• Use standard fonts that are easy to read (we avoid unreadable Gothic fonts!) and of which you are sure that they will be displayed well upon reception.
  Integrate your logo in high quality (to reinforce your brand image)
• Structure the information in one or more blocks (because an airy signature is more pleasant)
• Leave enough space between items (to avoid the “sardine box” effect)
• Choose a responsive HTML format rather than an image (for a perfect display on all devices)
• Test the rendering on different devices and email clients (because you can never be too careful!)
• Test your template with different profiles. Think of the ones that have a long title or name, not just the perfect case that suits you. That way, you can be sure that your design holds up for everyone!

Step 5: Adapt to Dark Mode

Today, you can't create specific settings for dark mode yet. So here are our tips

• Use images in PNG format with transparency (for optimal rendering)
• Provide a cartridge (white or colored) in the image for images or logos that cannot bear to pass on a black background (transparency provided only on white...).
• Check the readability of your signature in dark mode (because it's trendy and good for the eyes!)

Step 6: Integrate CSR issues

Even if the impact of email signatures is low, optimize your images anyway (compression, etc.). A cool alternative developed by Signitic: use text messages with colorful formatting. This allows for a commitment and a marketing impact as strong as images, but for a much lower weight. It's up to you to play!

And that's it! By applying these best practices, you will have a professional email signature that reinforces your brand identity and generates engagement. Test different versions to find the optimal signature according to your activity and your goals. A dedicated tool can simplify your life and optimize the end result.
