Viral Software

15 Best Viral Tools for Building & Scaling Pre-Launches, Waitlists, Competitions & Contests (2024)

I’ve had some good success with viral campaigns (competitions, contests, referrals, and more) across eCommerce and SaaS. There are many variables that can determine the success of your campaigns, and it’s genuinely really hard and a big challenge to make a campaign ‘go viral’. However, a key component that goes into these types of campaigns, which in the past has been quite expensive to build, is the technology. Now, there are platforms and tools to build these types of campaigns which, over time, have become easier, cheaper, and more accessible. I’m excited to highlight and take you through some of my personal favourites with which I’ve tested and had some good experiences using.

I've used hundreds (and hundreds) of software tools to help execute on key strategies for eCommerce growth, and I'm here to help highlight which tools, software and apps can help you scale your store.

As a growth marketing consultant for many years, some of the top questions I often get asked are particularly around how to make a campaign ‘go viral’, or what software can help build a viral referral engine for pre-launch campaigns or competitions. Questions like these…

  • “Hey Dan, what’s involved in getting a lot of emails in a short span of time?”
  • “Hey Dan, what tools can help get a campaign to go viral?”
  • “Hey Dan, what is the best platform to create viral competitions to get heaps of entries and emails?”
  • “Hey Dan, which software can help create a viral pre-launch waitlist for my startup?”
  • “Hey Dan, I want to replicate the success of what ‘X’ startup managed to achieve. What’s the best software to do this?”

There are plenty of other questions I get that are similar to these, and all of the questions I receive are really good. 

However, expectation management is key, as well as context. It’s actually a hard challenge to make a campaign or competition ‘go viral’. 

Having said that, with the right investment, resources, and planning, it is becoming easier to develop end-to-end campaigns that have the potential to go viral. 

A key component of what needs to be involved in a campaign, and giving it the best chance of success, comes down to choosing the right software that can enable capabilities of virality. 

Taking into account all the questions I’ve been asked over the years, I’m excited to put this guide together to share some of my top recommendations that I’ve personally had good experiences with when working with clients, brands, and startups. 

When it comes to choosing which viral tool is best for your business and primary campaign objective, what attributes and features should you be looking for?

Before diving into this guide full of awesome viral tools, it’s important to have some guidance into what factors and attributes can help you properly evaluate and choose the right platform for your business, plus whatever the key objective is that you’re wanting to achieve. 

It’s important to understand what your goal is, as the various solutions will be more applicable to certain objectives (for example, UGC contests and referral engines) over others. 

I’ve got here below some questions and items I normally look out for when it comes to researching viral marketing platforms. You can use the below as a baseline for things to look for when going through the tools. Questions to think about include:

  • What particular features and types of campaigns do they offer? Is the platform more skewed in terms of features as a social media contest platform? Or does it have features more applicable for pre-launch waitlists?
  • What contest types can you choose from? Can you run Facebook contests? Instagram contests? Pinterest maybe?
  • How advanced are the entries and rewards capabilities? Are multi-tiered rewards available? Do they offer points per entry? 
  • How do they successfully track entries? Is fraud protection available? (unfortunately, people will always try find a way around the entry mechanisms to try gain extra entries).
  • What do the design customisation options look like? 
  • When it comes to installation, can you embed a custom branded widget on a custom landing page that you created?
  • Does the platform provide automated email capabilities, or do you need to create emails yourself? (for example, emails could include updates on number of entries, or when a user has successfully referred someone).
  • What available 3rd-party integrations do they have? Do they provide Zapier, which can help unlock more integration possibilities? 
  • What does the paid plan look like for each of the platforms? Do they offer unlimited giveaway campaigns and/or unlimited entries? What certain features or benefits can you unlock if you decide to upgrade? 
  • Are there templates available to accelerate the process of building campaigns and workflows?
  • Do they offer case studies that highlight how companies have leveraged their platform to build campaigns for success?

Funnily enough, whilst there may be quite a few questions here to consider, this is by no means an exhaustive list. 

Every platform will have items you will need to do further research on in order to decide which platform is worth trialling and, ultimately, worth adopting for your campaigns. 

Alrighty, let’s dive into these viral marketing tools and understand what’s possible to build an awesome campaign (and achieve epic results).
