The Shopify & Mailchimp Auditor: Eliminate Inconsistent Promotions & Save Ad Spend
Are your marketing campaigns driving customers to broken promises? When your Mailchimp email promotes a 20% discount that isn't active on your Shopify store, you're not just creating a frustrating customer experience—you're wasting ad spend, tanking conversion rates, and eroding brand trust with every click.
This playbook implements an automated 'promo watchdog'. By designating Shopify as the single source of truth for all discounts, a daily automated workflow cross-references your active Shopify codes with the offers mentioned in your recent Mailchimp campaigns. If a mismatch is found, your marketing team gets an instant alert via email or Slack, allowing for immediate correction before it impacts sales or wastes more budget.
Expected Outcomes
- Drastically reduce wasted ad spend by ensuring promotional traffic lands on correctly priced pages.
- Protect brand reputation and customer trust with consistent, accurate cross-channel messaging.
- Increase conversion rates by eliminating the friction of mismatched offers between email and your store.
- Save hours of manual cross-checking with a fully automated daily audit and alert system.

Zapier
When a visitor submits a form on a Carrd website, it triggers a Zapier workflow. Zapier captures the submitted data, such as name and email address. It then passes this information to Mailchimp, which creates or updates a subscriber in a specified audience. This creates a seamless, automated bridge between your website's lead capture form and your email marketing list.
