Advanced Page-Specific Targeting

When it comes to data-driven marketing, personalization is the new black. Trigger campaigns based on device, source, or event (such as submitting a form), or hide from existing subscribers altogether.

Detect Referrals

Expecting a rush of referral traffic? No problem. Create page-specific messages for visitors based on where they come from, such as referral URL, UTM parameter, and more.

Hide from Subscribers

No one likes getting asked to join a newsletter when they’re already on it. Avoid annoying your website visitors by hiding campaigns from existing subscribers.

Target New/Return Visitors

Whether you want to welcome and wow new website visitors or reward returning customers, Sleeknote makes it easy to target users based on where they are in your marketing funnel.
