The Story of Plum Porch

Plum Porch is a small brick-and-mortar gift shop on Cape Cod run by two sisters. They spend less than 1% of their revenue on marketing and thus look for the highest ROI opportunities in terms of time and investment.

They have an active Facebook following where they do weekly Facebook Live shows. However, they have a smaller Instagram audience with 3,000 followers. They wanted to get their Instagram following more involved in their other activities by getting them on their email list.

Plum Porch saw using POPSMASH as an opportunity to engage their Instagram audience and get them on their email list to better track, nurture and convert those customers.

Why this approach works for Shopify stores of all sizes

Why did we use Plum Porch as our first case study?

There's a reason most case studies show large brands: It's often easier to do things at scale with large budgets. But those things often don't work well for small businesses with tiny budgets, especially with the recent ad and privacy changes impacting ROAS.

But by showing how this works for a small business like Plum Porch, it's easy to see how well these results scale to businesses of any size -- especially businesses with much larger Instagram followings.

Why? Because a business with 10X, 100X, or 1,000X the number of followers could use the same prize and approach and get significantly outsized results. The results scale better than any other marketing tactics available today.

Your Instagram followers are already interested in what you offer, that's why they follow you. This approach gets them into a channel (email marketing) that's easier to track, nurture, and covert.

How Plum Porch grew their email list from Instagram using POPSMASH

If you're unfamiliar with POPSMASH, it works by using Instagram giveaways as an incentive to email opt-ins.

Plum Porch used POPSMASH to run an Instagram giveaway for their followers and grow their email list by getting their Instagram followers onto their email list.

Instagram giveaways are a useful incentive for a few reasons:

  • Instagram users love them and are familiar with them
  • They drive 4X more engagement and 60X more comments than normal posts
  • They fit in nicely with normal content and paid promotion
  • They are one of the most cost-effective ways to drive meaningful action (like email opt-ins)
  • They scale well to any level of audience

This a long-term strategy that is effective when used consistently by running 1-2 Instagram giveaways per month. Here's how Plum Porch did it.

How Plum Porch structured their Instagram giveaway

Plum Porch relied on tried and true methods in running an effective Instagram giveaway using our tools and guidance. We've summarized it below.

The Instagram giveaway prize

Plum Porch used a $100 gift card, which is less than $50 in actual cost to the business, assuming keystone.

Another good prize option is using a popular, relatively low-cost product. For example, Hydroflask drives significant engagement using $30 water bottles as giveaway prizes.

The Instagram giveaway entry rules

Plum Porch used a simple and easy-to-follow set of entry rules to drive maximum engagement:

That's it. These rules are simple and easy to follow, with the added benefit of adding virality by requiring users to tag friends.

The Instagram giveaway post image

Plum Porch used an image of their brick-and-mortar store overlayed with the text 'Giveaway' to grab attention. The most important part of the giveaway image is showing 'Giveaway' in big letters to catch users' attention scrolling through their feeds.

What were the Instagram giveaway results?

This strategy works when done consistently, which is easy given it only takes a few minutes to set up. Running 1-2 Instagram giveaways per month using this process is optimal.

So how did Plum Porch do on their first giveaway with only 3,000 followers from a single Instagram giveaway in just 48 hours?

  • 142 entries (users who commented and tagged friends!)
  • 78 email subscribers
  • 54.9% entry to email conversion rate
  • 140 new Instagram followers (a 4.1% increase in just 48 hours)
  • 11.7% engagement rate

Shopify email marketing lead generation and list building results.

What's the most exciting thing? A Shopify store with 10X, 100X, or 1,000X followers could use the same approach with the same prize and get substantially better results since it scales so well.

How did they automate the process to put their Shopify email marketing lead generation & list building on autopilot?

Well, given this is a POPSMASH case study, I'm sure you already know the answer is 'they used POPSMASH.'

But how did they do it? How does it work?

The short answer:

  1. They created a POPSMASH campaign, which only takes a few minutes
  2. They created a post for their Instagram giveaway
  3. Then POPSMASH automated the rest, including tracking and verifying entries, handling T&C, etc.

We built POPSMASH to streamline the process, fit into your existing workflow, and only take an extra couple of minutes to set up. It works equally well for small stores, big brands, and the agencies they partner with. We'd love to help you like we helped Plum Porch.

How to do this for your Shopify store

Every Shopify store wants to grow its email list because email marketing is an amazing revenue channel with a great ability to track, nurture and convert customers.

But growing an email list is hard. Email doesn't have the discoverability of social media, where it's much easier to find prospective customers. But email marketing is also much more challenging to convert than social media.

The answer is to use both together by leveraging social for discovery, and email for conversions like Plum Porch did here.
