Best Email Signature Generators in 2025

March 31, 2025 No comments yet

Here’s how to create a professional signature for Gmail and Microsoft Outlook.

Actor AI Assistant allows you to add your own custom html signature at the bottom of your email drafts. You know that those drafts can be created automatically by Actor.


Introduction

HTML email signatures add professionalism to your emails. They include your contact information, logo, and social media links in a visually appealing format. This article covers the top generators that create HTML signatures you can copy and paste into any email client.

Why HTML Signatures Matter

HTML signatures look better than plain text. They include:

  • Your company logo and brand colors
  • Social media icons that link to your profiles
  • Professional formatting that works across email clients
  • Mobile-responsive designs that look good on any device

All those can be used together with Actor, so the signatures generated in each specific tool can be copied directly in Actor AI Assistant.
