The Pour Over upgraded from Growsurf to SparkLoop.

Here’s their unfiltered opinion...

We upgraded to SparkLoop because it's obviously the best referral software for media brands. Our previous solution was more expensive and not made for newsletter growth. We wasted so much time fighting to make it do what we needed.

Which solution is a better fit for you?

SparkLoop is the essential suite of tools for newsletter growth, trusted by thousands of leading media brands and newsletters.

Growsurf is a generic referral tool designed for software entrepreneurs. Ideal if you're building an app or SaaS product.

Deep-dive feature comparison

How do SparkLoop and Growsurf stack up where it matters? We asked publishers and newsletter operators to compare the two...

Easy, no-code integration

SparkLoop has a true, 2-click integration (and excellent relationships) with 15+ of the most popular email platforms. Plus the option to extend via our API and Zapier.

As a generic referral tool, Growsurf has only basic import and export functionality with a few email platforms. For a reliable integration, you'll need to invest weeks of developer resources.

Referral features

With SparkLoop it's easy to run milestone referral programs, giveaways, or both. You can include a beautiful referral widget (including the subscriber's referral link) inside any email, or on any website.

Growsurf has milestone referral program functionality but no giveaways. Due to the lack of direct ESP integrations, it isn't possible to reliably include a personalised referral link inside of your emails.

Reward fulfilment

SparkLoop makes fulfilling any kind of referral reward easy and fully automated. Including unique coupon codes, Zapier, digital goods and even merch/swag via our Printful integration.

Growsurf has some basic options for reward fulfilment, including coupon codes and digital rewards. Fulfilling any kind of physical reward, like branded merch, will be an expensive and manual process.

Anti-fraud protection

SparkLoop has industry-leading, fully customisable anti-fraud protection, built specifically for newsletters. It is the only solution proven to work at scale — even with huge giveaways and millions of subscribers.

Growsurf has in-built anti-fraud functionality. As a generic referral tool, their anti-fraud isn't optimised for how newsletter subscribers cheat — so you'll need to supplement with ongoing manual work.

High-volume capacity

SparkLoop is the solution of choice for seven of the world's ten biggest newsletter referral programs. Our security, scalability and extensibility are industry-leading. With designated account managers and fully customisable white-labelling.

As Growsurf is really designed for smaller software businesses, we couldn't find any information about their high-volume capabilities. It appears that certain elements of the platform can be white-labelled.


SparkLoop has tiered support from our team of newsletter growth experts. Including email, chat, and phone support. We also offer a concierge onboarding package for strategy support.

According to their website, Growsurf offers standard and priority support. This doesn't include phone-support or strategy support from someone with experience in newsletter growth.

Additional Features

As well as the core referral software, SparkLoop includes a suite of other tools to boost your audience growth. Including our one-click subscribe tool, Upscribe widget, Partner Network and more.

As a generic referral platform, Growsurf has great flexibility across all kinds of referral programs. From SaaS, to ecommerce, to one-off waitlists. Ideal if you aren't yet sure what your goals are.


There's a SparkLoop plan suitable for every newsletter operator. Starting at $16/month (paid annually) for up to 5'000 subscribers.

Growsurf plans start at $200/month for up to 10'000 subscribers. On average, operators who upgrade to SparkLoop find that Growsurf was costing them 3.7x more per referral.

The bottom line…

SparkLoop and Growsurf are very different solutions for different challenges. So when is each tool right for the job?

  • The best option for newsletter audience growth
  • Perfect for high-volume newsletters and media brands
  • Not ideal for one-off waitlists
  • A solid option for SaaS/app referral programs
  • Great if support and scalability aren't a priority
  • Not suitable for newsletter audience growth
