HollerBox Pro

HollerBox Pro adds layouts, triggers, scheduling, and CRM integrations to the HollerBox popup builder. Set where a campaign can appear, what user activity can trigger it, and where submitted leads should go.

Choose a format for each message

Create opt-in forms, offer popups, slide-in notifications, lightboxes, simulated chat conversations, and progress bars. Pro adds banner, footer bar, and sidebar layouts, plus FOMO sale notifications. Adjust colors and fonts in the visual builder, with custom CSS available for further styling.

Set placement and timing

Display rules control eligibility across posts, pages, and custom post types. Combine multiple rules, include or exclude locations, and filter visibility by user behavior. For eligible popups, triggers include inactivity, an element click, time on page, scroll percentage, and exit intent. Date scheduling sets when a campaign runs.

Send leads to connected utilities

Pro CRM integrations include ActiveCampaign, ConvertKit, Drip, HubSpot, Mailchimp, and MailPoet. HollerBox also connects with Groundhogg and can pass data through Zapier or webhooks. These options let a form submission flow to the selected marketing or CRM system.

Review campaign activity

Analytics track popup activity in real time, display impressions and conversion rates over time, and let you filter reports by date or see which pages convert most effectively. Use these reports to compare campaign results and adjust placement or timing.

HollerBox is self-hosted and does not limit the number of popups, impressions, or leads. GDPR-oriented options can hide popups and prevent cookies until cookie consent is given; the add-on is compatible with CookieYes.

Set up a campaign

Install HollerBox on a WordPress site and open the popup builder. Choose a layout, add an offer or opt-in form, style it, and define display rules. Then choose triggers and dates, configure any CRM, Zapier, or webhook connection, and use the reports to review activity once the popup is running.
