In its simplest form, the referral hub is a page for each of your subscribers to track their progress in your referral program. Here, they can find their unique referral link, social media share options, details of the rewards they've already won, and the next rewards on offer.

The rewards: Subscribers can see all the rewards they can win, which they've already won, and how many referrals to go until the next one.

The unique link: Individual to each subscriber and allows SparkLoop to attribute new referrals to the correct advocates.

Sharing options: Subscribers can share via Twitter, Facebook, Email, WhatsApp, LinkedIn, or Telegram with two clicks, or invite friends directly by email.

Referral stats: Total referrals made, referrals still pending, and how many referrals to go until the next reward.

SparkLoop automatically generates a subscriber_id for each subscriber and adds it as a custom field to your ESP. To give subscribers access to their referral hub, go to Referral Hub in your dashboard, select the "Email link" option, and copy the code to include in your newsletter.

If SparkLoop can't identify the subscriber, the page will show a form where they can enter their email address. They'll then be redirected to their referral hub. You can customize what this page looks like. Learn how to do that here.

SparkLoop offers an array of customization options to match your newsletter's branding and style. Read this support article to learn about the customization options.

You can either use a SparkLoop-hosted page customized to match your branding, or build your own custom page by embedding the referral hub widget. Here are detailed instructions for each option.

Once you've designed your referral hub, you're ready to share the link in your newsletter and get your subscribers excited to invite their friends and earn rewards.
