Summer is often treated as a slow season for e-commerce, but it doesn't have to be. With the right influencer strategy, a well-structured seasonal campaign can turn upper-funnel traffic built over previous months into real revenue, even during the quieter days when consumers are spending more time outside than online.
This case study breaks down how a UK-based home and living brand used Influencer Hero to run a summer sale campaign targeting the US market, generating $31,990 in sales in just 11 days, with 1,174 add-to-carts, 886 checkout initiations, and 308 completed conversions.
Here's the complete playbook, including the exact templates used at every stage.
The brand was entering the US market from scratch, no existing customer base, no brand recognition, no prior US marketing activity. A brand-new Shopify store had been created specifically for the US market, making this an isolated environment where every dollar of revenue could be cleanly attributed to influencer activity.
Without any other US marketing channels running in parallel, the brand needed influencer marketing to do it all: build awareness, establish trust with an unfamiliar audience, and convert that attention into sales, all within a compressed seasonal window.
KPIs the campaign was measured against:
The summer campaign didn't start in August. It started in March.
Five months before the campaign launched, the team began working with approximately 30 new US influencers per month through a gifting and affiliate model. The purpose wasn't immediate revenue, it was data collection.
By the time the summer campaign arrived, the team had performance data on roughly 150 influencers and knew exactly which ones could sell products and at what volume.
This prior data transformed the summer campaign from a speculative investment into a high-confidence allocation. Rather than guessing which influencers to include, the team could identify top performers with precision and offer them tailored packages that maximized ROI.
This is the 80/20 principle in practice: the majority of revenue in any influencer program comes from a minority of creators. The months before a seasonal campaign are the time to find out who those creators are.
Every decision in the summer campaign was designed to activate one of three core conversion drivers:
The Offer: a compelling discount gives consumers a concrete reason to act now rather than later. Without a clear offer, even well-placed influencer content struggles to convert. The summer sale discount was communicated prominently in the site header, social media bio, and through every influencer post.
Urgency (FOMO): a time-limited promotion creates pressure that moves fence-sitters to purchase. The campaign was run for 1–2 weeks, and the closing urgency push, coordinated across all participating influencers on the final day, predictably generated the campaign's largest revenue spike.
Social Proof: for a brand entering a new market with no existing reputation, influencer endorsement is the fastest way to build trust. Consumers in the US had never heard of this brand. But they trusted the creators they followed, and those creators' genuine enthusiasm for the product transferred that trust to the brand.
For the initial 5-month testing phase, influencer discovery used the following filters in Influencer Hero's search and discovery tool:
Additionally, the team used Influencer Hero to identify any US-based influencers who already followed the brand's Instagram account — a warmer starting point since they already had some familiarity with the brand.
Using Influencer Hero's search tool, the team built two separate outreach lists each month: one targeting influencers who already followed the brand's Instagram (warmer prospects), and one targeting new creators identified through the filter criteria above.
To onboard 30 influencers per month, the team needed to contact approximately 300 — reflecting the typical ~10% onboarding rate for gifting and affiliate campaigns. Rather than managing this manually, Influencer Hero's drip campaign tool automated the outreach sequences, including follow-ups that naturally doubled reply rates without additional effort.
All onboarded influencers were managed within Influencer Hero's CRM, where the team created unique affiliate links and personalized discount codes for each creator.
With performance data in hand, the team invited the top-performing influencers to the summer campaign.
For creators where past data justified a fixed payment, the invitation included a fixed fee alongside an affiliate commission and an exclusive discount code. For others, the offer leaned on affiliate commission and product gifting.

When influencers pushed back on budget, the team offered to increase the affiliate commission percentage rather than the fixed payment — keeping fixed costs predictable while giving creators upside if they performed well. For influencers who didn't reply, automated follow-up sequences in Influencer Hero ensured no potential partner was lost to an unanswered inbox.
Products were dispatched via Influencer Hero's gifting feature (integrated with Shopify) well ahead of the August 20 launch. On launch day, every confirmed influencer received a reminder email with their affiliate link and discount code — a step that consistently increases Day 1 posting rates and prevents the drop-off between "agreed to participate" and "actually posted."
The launch reminder template also coordinated the promotion's supporting infrastructure: a promotional banner in the website header, an updated social media bio with a CTA to the store, and an aligned Klaviyo email campaign to the subscriber list.
Once influencers posted, the team sent thank-you messages with a personalized sentence referencing the specific post content, alongside a gentle prompt to post again while the sale remained active. Influencers added to the brand's email newsletter also received sale-related communications — serving as additional reminders to share the promotion with their audiences.
In the final days of the campaign, all participating influencers received a closing reminder asking them to give their followers one last chance to access the offer. This closing sequence produced two reliable outcomes: a significant revenue spike as audiences responded to the coordinated urgency messaging, and free additional posts from creators willing to share a final reminder without incremental compensation.
The campaign's Shopify analytics showed the same pattern consistently observed across well-executed influencer seasonality campaigns: a sharp increase in sessions and sales at launch on August 20, steady mid-campaign activity, and a pronounced final-day spike driven by coordinated urgency messaging across all participating influencers.
The funnel data reinforces this: 1,174 add-to-carts against 308 completed purchases reflects a 26% cart-to-conversion rate, healthy for a brand with no US brand recognition, and a direct result of trusted influencer endorsement reducing the hesitation that unfamiliar brands typically face.
Because influencer marketing was the only active US acquisition channel during this period, Shopify analytics provided a direct, unambiguous view of campaign performance. Every session, every add-to-cart, every conversion came from influencer-driven traffic.
This isolation also validated the 80/20 principle in action, the majority of revenue came from the small subset of high-performing influencers identified during the 5-month testing phase.
The $31,990 summer result was directly enabled by the 5 months of prior influencer testing. Without performance data on 150 creators, the summer campaign would have been a wide, expensive guess.
With that data, budget was concentrated on proven performers, packages were sized to expected output, and the campaign started with a high-confidence roster rather than an uncertain one. The summer revenue figure understates the true value of the program — it's the payoff on months of systematic groundwork.
This campaign demonstrates something that applies well beyond summer: seasonal campaigns consistently outperform evergreen influencer programs in terms of conversion rate and short-term revenue, because urgency and offers give consumers a reason to act now.
The summer period, often dismissed as a quieter e-commerce window, generated $31,990 in 11 days, sourced entirely from influencer-driven traffic in a market where the brand had zero prior presence.
By using Influencer Hero to discover and filter influencers, automate outreach at scale, manage affiliate tracking, coordinate gifting, and process payments, all from one platform, the brand ran a full end-to-end campaign without the operational overhead that typically makes this level of execution unrealistic for lean teams.
