Email Signature Software Overview

What is Email Signature Software?

Email signature software centralizes management of employee email signatures and turns them into a low-cost marketing tool.

The benefits of standardizing employee email signatures including improving:

  • Branding

  • Email response rates

  • Quality control

  • Testing

Through email signature software, marketers can deploy banner ads, promote events, or send other marketing campaigns. Also, mail signature software can ensure outgoing emails contain appropriate disclaimers required for compliance with local law (e.g. anti-spam, GDPR).

Email Signature Software Features & Capabilities

Email signature software contains features and capabilities common to email marketing software, as well as features for optimizing the presentation and professionalism of signatures. Some of these features are:

  • Tamper-proof, centralized management of signatures

  • Branded signature customized to department or individual

  • Professional templates

  • Automated HTML signature generation

  • Drag-and-drop editor

  • Real-time updating of signature fields or layout

  • Dynamic or personalized ad banner campaigns

  • Mobile adapted layout and view

  • Social media icons

  • Support for animation, GIFs, graphics

  • Directory integration to pull contact information

  • Multiple signature or email aliases for user role

  • Industry-specific or policy-guided disclaimer


Email signature software vendors boast a number of integrations to ensure functionality across email clients and servers. However, many signature apps are bound to a specific service like Outlook and Exchange, or Gmail and G Suite. Email signature tools pull information from various sources like a corporate directory (e.g. Active Directory) for automated field population and contact data updating. Signatures can be linked to social media sites, RSS feeds, or a YouTube channel. Content can be pulled from these sites (e.g. a blog post or update) for interactivity.

To support marketing campaigns email signature tools must integrate with other business applications. This allows them to provide personalized advertising and messaging, or support A/B testing and segmentation. These integrations most commonly include company CRM and marketing automation platform (MAP). Some email signature tools also integrate with sales accelerators, account-based marketing (ABM) platforms, sales email tracking, or other sales tools.

Pricing Information

Email signature disclaimer and marketing software is available on a subscription basis. Vendors often bill monthly but offer annual billing as well. The most common pricing determinant is number of signatures managed or user licenses. Simple free plans are available, and 30-day free trials are common.

Lower tier plans ranging from around $2 to $10 for each signature managed per month, depending on feature breadth (e.g. inclusion of ads, 1-to-1 targeting). Larger plans accrue per-user discounts as aggregate cost increases. Enterprise plans supporting large user groups cost less than $1 per user license. More complex service offerings (e.g. those including sophisticated marketing capabilities) may be atypical, and more expensive.
