Call to Action (CTA) in Email

A call to action (CTA) in email is a prompt — typically a button, link, or banner — that encourages the recipient to take a specific action such as visiting a website, scheduling a demo, downloading a resource, or registering for an event. CTAs in email signatures turn routine correspondence into conversion opportunities.

Key Aspects

Conversion Driver

CTAs guide recipients toward desired actions, turning passive email reading into active engagement.

Visibility

Well-designed CTAs with contrasting colors and clear text stand out in the signature layout.

Trackable

Each CTA can include tracking parameters to measure clicks and attribute conversions.

Frequently Asked Questions

How many CTAs should an email signature have?

One primary CTA is ideal. Adding too many CTAs dilutes attention and reduces click-through rates. If you must include multiple, make one visually dominant.

Should the CTA be a button or a text link?

Buttons generally perform better because they are visually prominent. However, some email clients do not render buttons consistently. A well-designed banner image with a CTA is the most reliable approach.

How often should I change the CTA?

Update CTAs every 4-8 weeks or when marketing campaigns change. Stale CTAs lose effectiveness as regular recipients stop noticing them.

Can different employees have different CTAs?

Yes. Sales teams might have a "Schedule a Demo" CTA, while support teams might link to a satisfaction survey. Siggly supports rule-based CTA assignment by department or role.
