In recent discussions on the Shopify Community forums, multiple store owners have reported issues with fake newsletter subscriptions. One user shared their experience of receiving a sudden influx of email subscribers—rising from 213 to 259 in just two days. Despite enabling Google reCAPTCHA, many of these new subscribers appeared suspicious, with discrepancies between their listed locations and the store’s primary market.

Another user highlighted the challenges of dealing with fake customer accounts generated through the Customer Login portal. Despite implementing security measures like reCAPTCHA and even removing the “Create account” link from their site, they continued to face issues with fake accounts, which did not affect their traffic analytics but appeared directly in their customer lists. This ongoing problem has been likened to a virus, significantly impacting their marketing efforts and prompting them to consider moving their store if the issue persists​

Understanding Fake Newsletter Subscriptions

Fake newsletter subscriptions on Shopify are a significant issue that can impact store operations, email deliverability, and marketing effectiveness. Here’s a closer look at what fake newsletter subscriptions are, why they happen, and their implications:

What are Fake Newsletter Subscriptions?

Fake newsletter subscriptions occur when bots or malicious actors sign up for your newsletter using invalid, temporary, or random email addresses. These can include:

  • Disposable Email Addresses: Temporary emails that are created for short-term use.
  • Invalid Email Addresses: Randomly generated emails that don’t correspond to real accounts.
  • Bots: Automated programs designed to repeatedly fill out sign-up forms.

Why is This Happening on Shopify?

Bot Activity:

  • Automated Testing: Bots are often used to test the security and functionality of e-commerce websites. This includes signing up for newsletters to see if the forms can be exploited or to gather information.
  • Resource Exploitation: Bots may target your store to drain server resources, causing delays and increased operational costs​.

Email Harvesting:

  • Data Collection: Malicious actors might use fake sign-ups to collect valid email addresses from auto-responses and newsletters, which can then be used for spam or phishing attacks​.

Negative SEO Tactics:

  • Competitor Sabotage: Fake subscriptions might be a strategy used by competitors to harm your store’s email marketing campaigns. High bounce rates from invalid emails can damage your sender reputation, reducing overall deliverability and effectiveness​​.

Insufficient Security Measures:

  • Lack of Protection: Without robust security measures such as CAPTCHA, double opt-in, and email verification, it is easier for bots to penetrate your system and create fake subscriptions. Many Shopify stores may lack these essential defenses, making them vulnerable to such attacks​ 

Testing Store Defenses:

  • Probing for Vulnerabilities: Bots might be testing your store’s defenses to identify and exploit weaknesses. This can be part of a larger strategy to breach security measures for more severe attacks later on​ 

Implications of Fake Newsletter Subscriptions

Inflated Subscriber Counts:

  • Misleading Metrics: Fake subscriptions can inflate your subscriber count, giving a false impression of your audience size and skewing your analytics.

Email Deliverability Issues:

  • High Bounce Rates: Sending emails to invalid addresses results in high bounce rates, which can damage your sender reputation and lower your overall email deliverability​ 

Resource Wastage:

  • Increased Costs: Managing and filtering out fake subscribers can waste valuable resources, both in terms of time and server capacity.

Reduced Campaign Effectiveness:

  • Lower Engagement: Fake subscribers do not engage with your content, leading to lower open and click-through rates, which can hurt your email marketing performance metrics.

Expert commentary

The most popular way to avoid fake signups is using CAPTCHA. While CAPTCHA helps deter automated bots, it is not foolproof against sophisticated attacks and human-powered spam. Advanced bots can bypass CAPTCHA, and malicious actors can still manually input fake data. Additionally, CAPTCHAs can frustrate genuine users, potentially reducing legitimate sign-ups. Comprehensive security measures, including email verification, behavioral analysis, and rate limiting, are necessary to effectively combat fake subscriptions.
