Meet the Maker:
Louis Nicholls & Manuel Frigerio

The story of this SaaS marriage begins at a chance meeting at a tech conference in London in 2019. Shortly afterwards, one of Louis’ consultancy clients commissioned Manuel to build them a referral program – a supercharged version of his ReferralHero referral tool.

Fast-forward to August 6th, 2020 and SparkLoop was born. Their vision for the tool is to be the “default, no-brainer newsletter referral tool for the largest newsletters in the world.” Easy to use, proven to work and much loved by customers, SparkLoop now helps thousands of email authors to acquire new subscribers cost-effectively and faster than ever. Their impressive list of clients includes James Clear, Tim Ferriss and Shane Parrish, they’ve formed formidable partnerships with the likes of ConvertKit, and built free tools such as Proof and Reactions for anybody keen to grow their email newsletter.

The Product

How we tested SparkLoop for this review

Lured by its promised returns and stories of “50k new subscribers in 5 months” I was genuinely excited to try SparkLoop.

SparkLoop offer a free course of email list growth gold that comes with a free 30-day trial of SparkLoop Pro. Perfect for anybody wanting to test the water. Spread across 5 emails it offers bursts of inspiration and best practice, with a focus on applying the same tactics to your own email referral campaign.

SparkLoop newsletter referral course review

I’d use SparkLoop to grow subscribers to my Marketing #SaaSclub newsletter. It has a low starting point of 500 subs and with that I wasn’t sure a newsletter referral program would work for my (tiny) audience.

I also didn’t want to blow the bank on rewards. Surges is a side project after all. So rewards would be largely free and digital only, unless a subscriber was sending serious numbers my way.

Getting started with SparkLoop

Course completed, connecting SparkLoop to your email marketing provider takes just a few clicks.

SparkLoop claims you’ll be referral-ready in 15 minutes. Once connected, individual subscribers are given a unique referral link directly into the body of your newsletter and any referrals are automatically detected and rewarded according to the criteria you set.

Both parties get their own SparkLoop dashboard, so it keeps them motivated and gives you a bird’s eye view of your entire campaign. The whole process is super simple, however for anybody needing a bit more handholding, SparkLoop offers a free concierge onboarding service.

SparkLoop features you’ll love

  • 📨 More referrals, more rewards

    Incentives are subscriber superfood.

    With SparkLoop you’re in total control of rewards. Choose from a single reward, multiple reward tiers, or recurring rewards. Whether you want to give away merch, discount codes, exclusive access, free membership for a few months or a free e-book, SparkLoop makes it easy to create, track and optimise rewards that actually work.

    SparkLoop is extremely polished. With very little effort you’ll have a good looking and highly effective viral referral scheme on your hands.

    I’m on a side project budget, so will be going for affordable and easy-to-create rewards. Think digital “thank you”s and drop-shipped swag, with a total budget of $250.

    One of the former free course graduates, Aleyda, advised: “it’s really important to have a reward for 1-3 referrals that costs nothing so that every subscriber knows they’ll get something in return for sharing.” Wise words.

    The SparkLoop rewards library is full of inspiration for rewards that can grow your email list. Go check it out!

  • 💌 Baked into your newsletter

    SparkLoop lets you bake a referral program into your standard newsletter.

    Connect it up to your MailChimp, ConvertKit, MailerLite, Campaign Monitor, Active Campaign or Drip account for amazing two-way data sync. This allows you to track new subscribers, insert unique referral links in your newsletter and for your referrers to attract new subscribers with a single click. No form filling needed!

    Subscribers can share the referral link any way they please, including in social media posts, in blog posts or guests posts, a QR code or adding a call to action into their marketing emails. The single click sign-up is a win/win for everyone.

    One of the main reasons this all works so well is because it’s unshakably upfront and simple. “Refer a friend” or “Send to a friend” links are usually hidden away at the bottom of emails. SparkLoop makes the ask a lot more direct and appealing. Also, if the prospect takes a detour, SparkLoop’s tracking script tracks referrals across any sign-up form or pop-up anywhere on your website.

  • 🎁 Reward emails and fulfilment – easy-peasy

    Don’t fret about fulfilling all those rewards. You’re busy enough.

    SparkLoop can be setup to automatically send a congratulatory email to referrers due a reward. If the reward is digital (e.g. a PDF, discount, course etc), you can include a link to download it in the email itself. Clever!

    Whilst we’re on emails. SparkLoop can also automate ‘You’ve made your first referral’ emails and those to your new subscribers resulting from the campaign. Merge tags, such as ‘name’, ‘number of referrals’ and ‘referrals needed for next reward’ keep referrers feeling values and motivated.

  • 📈 Dashboards for all - keep motivating

    SparkLoop referral dashboard review

    SparkLoop keeps everyone in the loop with super simple and easy-to-find dashboards.

    Everything referrers need to stay motivated (subscriber count, reward tiers, key links) is in one place and wrapped in your branding. Referrers can also directly access their individual dashboard by following the unique link in your emails – no messing around with logins and lost passwords.

    The unique referral link means every new sign up is permanently credited to the referring subscriber’s account. SparkLoop ensures the all-important mix of accuracy, transparency and fun needed for any referral or email marketing campaign.

    As the campaign owner, you’ll get a day-by-day breakdown of new subscribers, new referrals and traffic to your landing page. You can also see top referrers to drop them a “thank you” note, outside of the rewards system.

  • 🏆 Giveaways - inject more urgency

    Giveaways are great if you’re starting with a small audience or want to grow your email list even faster.

    SparkLoop giveaways review

    The Refer-to-Win Giveaway is very similar to the normal referral program you might run with SparkLoop, but instead of rewarding referrals with prizes, they get entries into a prize draw. The more referrals they make, the better their odds of winning. Email marketing 101.

    SparkLoop powers these end-to-end too. It’ll even pick a winner for you, ensuring a fair draw. You can select the start and finish date, the entries per referral, the number of prizes and advanced anti-fraud measures (e.g. double-opt-in entries) to stop anyone gaming the system. Just like a SparkLoop referral campaign, Giveaways can also be embedded directly into your email newsletters.

  • 📝 Subscribe pages – a single editable template

    Although SparkLoop’s one-click subscription link is a godsend, you may also wish to send people to a landing page.

    SparkLoop’s Subscribe pages are designed with conversion in mind. They’re super minimalist, featuring just enough info to persuade and reassure potential new subscribers. However, I have to say I prefer Unbounce’s advanced landing pages, boosting better looking templates, building grid, social proof, A/B testing and AI optimisation.

    Still, it’s a much-needed feature and will do the job of converting website visitors into subscribers and potential customers. Make sure you point yours to a custom domain (e.g. and don’t forget to set your success message and automated email marketing welcome.

Things to consider

  • SparkLoop doesn’t have a free plan, however it does have some amazing free tools!

  • SparkLoop Magic Link – one-click sign-ups

    Friction is the nemesis of newsletter traction.

    Add a free SparkLoop Magic Link your newsletter and let readers opt-in to your email list with just one click. No need to go to a landing page or fill out a sign up form with contact information. This moment of magic is perfect for contra deals and far more effective than placing an ad or bog standard marketing campaigns.

    Like the main SparkLoop product it works with most email platforms, including Mailchimp, ConvertKit, MailerLite, Campaign Monitor, Active Campaign, PostUp, Drip, SailThru, HubSpot and AWeber.

  • SparkLoop Proof – verified subscription stats

    I covered the power of social proof with Fomo. Build credibility to your claims by showing off honest stats, verified by SparkLoop.

    Because you’ve granted SparkLoop access to your email provider, it can automatically give up-to-date metrics as you grow your email list. The ‘Verified by SparkLoop’ seal of approval can be set to show your total subscribers or new subscribers added in the last 7-days.

    Why not go further and augment this feature with your own manual list building stats, such frequency, open rates and logos of big brands signed up to your newsletter.

    Running a startup and sending newsletters can be a lonely affair.

SparkLoop Alternatives

Viral Loops is the closest and biggest SparkLoop competitor. It offers the same code-free setup, 1-click integration with email providers, unique invite codes and tiered rewards, however has a broader range of templates beyond just growing your newsletter list. Viral Loops has templates for Shopify stores, Facebook Messenger, Prelaunch campaigns, Leaderboard Giveaways and more regular email marketing. This extra capability comes at a slightly higher cost as your subscriber numbers start to hit 25,000+.

SparkLoop Support   👍  or   👎

Creating a referral scheme involves a bit of upfront effort. Thankfully, SparkLoop offer a free course full of hints and “How to grow your email list” content. ‘SparkLoop University’ as they call it, is only 5 emails so you’d be silly to start your campaign without it.

There’s also comprehensive support documentation, packed with step-by-step guides for every aspect of your referral scheme. And for anything else they’re only an email or tweet away.

The Verdict

Surges score


If a professional referral scheme seems out of reach, think again.

SparkLoop makes it possible, easy and scalable, promising to work miracles for your email list growth.

Having never run one myself previously, I was blown away by how quick the whole process was with SparkLoop. Dreaming up perks, deciding tiers, embedding unique links into your newsletter and tracking and rewarding referrals is disarmingly easy. The one-click sign-up link is really the icing on the cake, removing any last friction that might deter someone from joining your list.

SparkLoop reliably attributes every new subscriber to a source and can automatically dish out digital rewards as your referrers move up the reward table. This keeps everyone fully in the loop and motivated to unlock bigger rewards – the cornerstone for any successful referral campaign. As humans, we’re hard wired to share, but we just need a little encouragement and the occasional incentive that SparkLoop presides over.

If there’s one criticism, it’s SparkLoop’s landing pages. They say the single template is the result of analysing hundreds of successful campaigns, but a bit more creative freedom would be appreciated. Still, that’s me being picky. Many referral campaigns won’t need a landing page at all.

It’s no surprise SparkLoop powers some of the biggest newsletters of all time. Having the best newsletter in the world means diddly squat if nobody knows about it. SparkLoop is a sure-fire way to create a stir about yours and grow your email list cost-effectively and with minimal effort.
