<p>Campaign Builder, also known as Sky Campaigns, is a WordPress email marketing and subscription campaign plugin for site owners who want to grow an email list, display opt-in popups, collect subscribers, send newsletters, and create automated follow-up emails without leaving WordPress.</p>
<p>Use Campaign Builder to create popup subscription forms, embed inline newsletter signup forms with a shortcode, organize subscribers by campaign, export subscriber data, send email broadcasts, and build simple auto-responder sequences for new subscribers.</p>
<p>The plugin is designed for bloggers, small businesses, WooCommerce stores, agencies, course creators, coaches, service providers, publishers, and WordPress site owners who need a lightweight email campaign tool inside the WordPress admin area.</p>
<p>Sky Campaigns stores campaign and subscriber data in your own WordPress database. Emails are sent through WordPress using <code>wp_mail()</code> by default, so your existing SMTP plugin or transactional email plugin can handle delivery. If you prefer dedicated sending settings for this plugin, you can enable the optional built-in SMTP configuration.</p>
<h4>Why Use Campaign Builder?</h4>

<h4>Subscription Popups for WordPress</h4>
<p>Campaign Builder helps you create email subscription popups that can appear on the front end of your WordPress site. Each campaign can have its own design, trigger, display rules, and subscriber list.</p>
<p>Use popups for:</p>
<ul>
<li>Newsletter signup forms.</li>
<li>Lead generation campaigns.</li>
<li>Blog subscription campaigns.</li>

<li>Download or announcement opt-ins.</li>
<li>Seasonal marketing campaigns.</li>
<li>Store promotion subscriber lists.</li>
</ul>
<h4>Inline Newsletter Signup Forms</h4>
<p>Not every signup form needs to be a popup. Campaign Builder includes a shortcode for inline subscription forms.</p>
<p>Use this shortcode to show a form inside posts, pages, widgets, landing pages, or supported page builders:</p>
<pre><code>[skyca_form campaign_id="1"]
</code></pre>
<p>Replace <code>1</code> with the campaign ID you want to display.</p>
<p>Inline forms are useful for:</p>
<ul>
<li>Blog sidebar newsletter forms.</li>
<li>Landing page opt-in sections.</li>
<li>Footer subscription forms.</li>
<li>Content upgrade sections.</li>
<li>About page signup forms.</li>
<li>Contact page newsletter forms.</li>
</ul>
<h4>Popup Templates</h4>
<p>Campaign Builder includes six popup templates so you can quickly match your form to your website style.</p>
<p>Each campaign can use its own template, text, colors, button label, and optional image URL.</p>
<h4>Popup Triggers</h4>
<p>Choose how and when your WordPress subscription popup appears.</p>
<p>Available trigger types:</p>
<ul>
<li>Time delay in seconds.</li>
<li>Scroll depth percentage.</li>
<li>Exit intent.</li>
<li>Immediate display.</li>
</ul>
<p>These triggers help you show opt-in forms at more relevant moments, such as after a visitor spends time on a page, scrolls through content, or moves toward leaving the page. For more advanced triggers, you can <a href="https://7thskysoftware.com/wordpress-plugins/sky-campaign-builder/" rel="nofollow ugc">Upgrade to Pro</a></p>
<h4>Campaign Display Targeting</h4>
<p>Campaign Builder lets you control where each campaign appears.</p>
<p>Campaign display options include:</p>
<ul>
<li>Entire Site</li>
<li>All Pages</li>
<li>All Posts</li>
<li>Selected Pages</li>
<li>Selected Posts</li>
</ul>
<p>Selected Pages and Selected Posts include searchable pickers in the campaign editor, making it easier to show a campaign only on specific content.</p>
<p>Example uses:</p>
<ul>
<li>Show a blog newsletter popup only on posts.</li>
<li>Show a product waitlist campaign only on selected landing pages.</li>
<li>Show a general email subscription popup across the entire site.</li>
<li>Show a category-specific lead magnet on selected pages.</li>
<li>Run separate campaigns for different parts of your website.</li>
</ul>
<h4>Subscriber Management</h4>
<p>Subscribers are stored in your WordPress database and linked to the campaign they joined.</p>
<p>The Subscribers screen lets you:</p>
<ul>
<li>View subscriber email addresses.</li>
<li>View first names and last names when available.</li>
<li>See which campaign each subscriber joined.</li>
<li>Check subscriber status.</li>
<li>View subscription dates.</li>
<li>Search subscribers by email, first name, or last name.</li>
<li>Filter subscribers by campaign.</li>
<li>Review total and active subscriber counts.</li>
<li>Export subscribers to CSV.</li>
</ul>
<p>Public forms collect the email address and, when enabled, the first name field. The database also includes a last name field for merge tags, compatibility, and future/custom integrations.</p>
<h4>Welcome Email</h4>
<p>Campaign Builder can send a welcome email when a new subscriber joins a campaign.</p>
<p>This is optional. You can enable the welcome email for a simple confirmation message, or disable it and rely on campaign-specific auto responders instead.</p>
<p>From <strong><em>Campaigns > Settings > Email</em></strong>, you can configure the welcome Email.</p>
<h4>Auto Responders</h4>
<p>Auto responders are delayed follow-up emails connected to a specific campaign.</p>
<p>Use auto responders to send:</p>
<ul>
<li>Welcome sequences.</li>
<li>Course introduction emails.</li>
<li>Lead nurture emails.</li>
<li>Product education emails.</li>
<li>Follow-up offers.</li>
<li>Onboarding messages.</li>
<li>Drip campaign messages.</li>
</ul>
<p>Each auto responder includes:</p>
<ul>
<li>Campaign selection.</li>
<li>Internal name.</li>
<li>Email subject.</li>
<li>HTML body.</li>
<li>Delay in days.</li>
<li>Delay in hours.</li>
<li>Send order.</li>
<li>Active or inactive status.</li>
</ul>
<p>When a new subscriber joins a campaign, active auto responders for that campaign are added to the email queue. WordPress cron processes the queue hourly, up to 50 pending auto responder emails per run.</p>
<h4>Newsletters and Broadcast Emails</h4>
<p>Campaign Builder includes a newsletter screen for creating and sending broadcast emails to subscribers.</p>
<p>Each newsletter includes:</p>
<ul>
<li>Internal name.</li>
<li>Email subject.</li>
<li>HTML body.</li>
<li>Optional campaign targeting.</li>
<li>Draft or sent status.</li>
<li>Sent count.</li>
<li>Sent date after delivery.</li>
</ul>
<p>You can send newsletters to:</p>
<ul>
<li>All active subscribers.</li>
<li>Subscribers from one selected campaign.</li>
<li>Subscribers from multiple selected campaigns.</li>
</ul>
<p>If no campaign is selected, the newsletter sends to all active subscribers. Newsletters are sent when you choose Send Now or Save & Send Now.</p>
<h4>Unsubscribe Links</h4>
<p>Newsletter emails include an unsubscribe link. When a subscriber uses that link, Campaign Builder marks matching active subscriber records for that email address as unsubscribed and stores an unsubscribe date.</p>
<h4>Campaign Builder Pro</h4>
<p><a href="https://7thskysoftware.com/wordpress-plugins/sky-campaign-builder/" rel="nofollow ugc">Campaign Builder Pro</a>, also known as Sky Campaigns Pro, adds advanced popup targeting, visitor behavior triggers, frequency controls, scheduling options, and CRM integrations.</p>
