Targeted email signatures made simple

Dynamically change signatures based on audience

Use different rules for internal vs. external emails, target specific domains or addresses, or sync with Salesforce and HubSpot lists. Marketing can run tailored campaigns and promotions to specific audiences without creating extra work for IT.

How Signature Rules work

Design your signature

Use our drag-and-drop designer to create a professional, on-brand signature with logos, banners, social links, and more. No coding required.

Set your rules

Choose exactly when and where the signature applies. Target by sender, recipient, date, or even email content.

Test before you deploy

Use the built-in Signature Rules Tester to simulate sending emails between chosen senders and recipients. Instantly see how your rules are applied, in what order, and which signatures will be used.

Track engagement with analytics

Measure performance by signature, or even by individual elements like banners or links. You can also monitor overall signature usage across your business.
