The Top 6 Ecommerce Shopify Apps in 2021


Growing your Shopify store without apps would be difficult. 

They unlock superpowers and enable you to do things that would otherwise be impossible without a (seriously good) web developer.

The following 6 apps are not necessarily ‘the best’ apps ever because that’s a highly subjective claim. Instead, this list of apps combines awesome functionality and great value, which I think is what most HeapsGood customers are on the hunt for.

So, without further ado here are my top 6 Shopify apps of 2021...

1. Klaviyo

It’s probably not much of a secret by now.

Klaviyo is the leading email marketing app for Shopify stores, and among the best customer retention tools in the eCommerce industry.

There are two key reasons why Klaviyo could be incredibly useful for your brand.

First, it allows you to build automations based on user behaviour such as cart abandonment, email signups and more. This lets you create personalised customer journeys and engage users at the right time with the right message. I have an article that goes in depth on this topic here.


Second, you are able to segment your audience based on tons of parameters from average order value to product category interests and everything in between. This ensures the email campaigns you send are always relevant and provide value for your audience.

2. Gorgias

Gorgias is the ultimate customer service help desk for Shopify store owners. After trying it, you won’t ever want to use email again.

What are the main advantages of Gorgias over traditional email customer service? 

For a start, you have all of your Shopify customer data integrated with the helpdesk. Contact information, order history, tracking – it’s all there right at your fingertips.


Then there are the macros. These are delightful, one click responses you can build for all of your most frequently asked questions. You can even include variables like first name, tracking number, order number and more, so you can get information to your customers with minimal effort!

It’s no surprise that an amazing customer experience is key to growing an online brand. Gorgias is part of the customer experience I have built for my brands and recommended to friends in the eCommerce industry.

3. Feed for Google Shopping by Simprosys

This app is crazy good value, probably why it’s rated 4.9 stars from over 2500 reviews. 

Most eCommerce brands need to get involved in Google Shopping, Bing Shopping and Facebook Ads at some point. 

And this app allows you to seamlessly connect your product catalogue to each of these marketing channels in a few clicks.

There are more expensive options in the market like Data Feed Watch; and other apps that are built for specific channels like Awesome Facebook Product Feed, if you need a bit more functionality. 

For most brands though, Simprosys will get the job done at low cost.

4. Judge.Me and Okendo

The bottom line is that social proof will help customers trust your brand and increase your conversion rate, and reviews are one of the best vehicles to generate social proof.

Reviews enable your customers to champion the benefits of your products (which of course requires you to have a great product and experience in the first place).

I’ve listed two review apps here because they serve different purposes depending on the size of your eCommerce business. 

Judge.Me is a fantastic budget option for collecting and displaying reviews, with a free plan and an advanced plan priced at $15. It has all the basic functionality required and lets you push reviews to organic Google listings and Google Shopping listings too.

Okendo is more feature rich and can do useful extras such as offering a discount in exchange for a review and pushing reviews to Google Sellers for Search Ads. We also like Okendo because it’s an Aussie company! 


5. Searchanise

Searchanise is a super powerful app for adding instant search functionality to your website. 

This is a must-have for stores with large catalogues and will help users find what they’re looking for, rather than scrolling endlessly through your collection pages.

I haven’t found another search app that is such great value for money. There are more high-end options out there like Klevu, for example, but for many merchants I wouldn’t think it justifies the price.

For my other brand Threadheads, I use Searchanise so have a play with it there if you’re interested.

6. Postscript

Okay this is my smokey for 2021. 

Postscript is fast-growing into the best SMS marketing tool for Shopify and is super simple to set up.

Why start using SMS?

Well, with mobile accounting for 72.9% share of overall devices used to make eCommerce purchases in 2021, for many consumers it’s more convenient to receive communications via text rather than email.

Most SMS strategies on Postscript are now focusing on segmentation (you can import your segments via Klaviyo) and creating an exclusive ‘VIP’ feel to the messaging. You can also use Gorgias to receive and answer responses from your customers.



There you have it, my top Shopify eCommerce apps for 2021.

    As someone who’s looking to get a bit more serious with an online Vinyl store – Searchanise is an Instant Winner, where has this been all my life! As both a Threadheads and Heaps Good customer (without honestly realising the link until reading this Blog) – I’ve also just installed Klaviyo. I gotta say I love the Threadheads Lionel Richie email I got the other day haha – that sold me on Klaviyo alone lol!

  • Ace

    Hey Daniela! I’m a huge fan of Shopify. I’ve spoken at length about its benefits on the Official Shopify Podcast among other places. The Shopify platform is built for ecommerce, whereas Wordpress is a blogging platform first that has ecommerce functionality via Woocommerce. Hope that helps! Feel free to reach out to me at if you need any tips on getting started :)

  • Daniela Hernandez

    Would you recommend Shopify over Wordpress ?

  • Ace Reunis

    Hey Jack, really glad you got some value out of it. We’ve got lots more blogs planned for the coming year. Which apps did you end up going with and how are you finding them?

  • Jack

    Awesome blog! Super handy for me as I wasn’t too sure which apps would provide me the most value. Now I’m interested in implementing some of these tools into my new eccomerce store. Thank you!
