Give the Campaign a Friendly Name<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Locate the <strong>Campaign Identifier<\/strong> field.<\/li>\n\n\n\n<li>Enter a clear label such as <code>FestivalOffer<\/code>, <code>RenewalReminder<\/code>, or <code>FeedbackDrive<\/code>.<\/li>\n\n\n\n<li>This identifier appears in activity logs, API responses, and helps your team filter reports later.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">3. Paste the Recipient Numbers<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In the <strong>Mobile Numbers<\/strong> textarea, paste the list you want to call.<\/li>\n\n\n\n<li>You can separate numbers with commas, spaces, or line breaks; the platform normalises them automatically.<\/li>\n\n\n\n<li>The helper text (<code>mmcount<\/code>) beneath the box updates as you paste, showing how many contacts you&#8217;re about to call.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Formatting best practices:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If you paste a list with mixed separators, the platform strips unwanted characters for you.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">4.
