Square Marketing is an integrated solution designed to help you connect directly with your customers. You can easily expand your business using personalized email and text campaigns. These campaigns can be sent once or set up as recurring automations. Square Marketing helps you promote new products, announce events, or share last-minute deals. It drives traffic directly to your online or physical stores. ✅
This system also works well with the free Square Customer Directory. This built-in CRM tool is integrated with your Square Point of Sale. It gives you a complete view of your customers, including their purchasing habits. This integration allows you to sync sales data and track sales attribution across all your channels and store locations.
We highlight the main differences and pick a winner for each feature.
Square Marketing offers unrivaled native POS integration. Mailchimp requires extensive third-party connectors for similar functionality.
Mailchimp connects with over 300 platforms like Shopify and Google Analytics for sales data syncing. This offers massive flexibility across various business tools. Mailchimp requires setup effort to unify sales and marketing data sources. Square Marketing is natively built into the Square POS and Customer Directory ecosystems. You get a seamless, 360-degree customer view right away, requiring zero setup time. Thus, Square Marketing is perfect if your entire business already runs through Square operations. Mailchimp is better if your tech stack is specialized and varied.
Mailchimp limits sends and charges overages; Square Marketing offers unlimited email sends. Square Marketing's pricing is more transparent for volume.
Mailchimp’s paid plans limit monthly email sends to 10X to 15X your contact count. Users report frequent automatic charges when they exceed contact limits, making costs unpredictable. Square Marketing charges a fixed monthly fee determined only by your contact tier, starting at $15 for 500 contacts. All paid tiers include unlimited email sends. Mailchimp provides a permanent, robust Free plan for up to 500 contacts. Square Marketing only offers a 30-day Free Trial of its paid services. Choosing Square Marketing simplifies budgeting if you plan to send emails frequently to fixed contact tiers.
Mailchimp uses generative AI and custom code; Square Marketing relies on simplicity and prebuilt templates.
Mailchimp Standard and Premium users access powerful generative AI tools to create on-brand content faster. Mailchimp also supports custom-coded email templates for highly unique designs. Square Marketing focuses on simple prebuilt templates and speed of deployment for busy small business owners. It lacks advanced design customization or AI writing assistance. If cutting-edge design flexibility and content generation are essential, Mailchimp is the stronger choice. Square Marketing prioritizes functional communication ready to deploy instantly.
Square Marketing tracks attributed sales natively; Mailchimp requires syncing external e-commerce data. Square's data is immediate.
Square Marketing tracks attributed sales and coupon redemptions directly in the Square Dashboard. This native integration ensures accurate, real-time data across all sales channels. Mailchimp relies on syncing sales data from integrations like Shopify and connecting it to reporting funnels. This process works but lacks the seamless integration of Square. For owners measuring marketing ROI against POS transactions, Square Marketing provides unequaled, singular source data. This is a critical advantage for physical retailers.
Square Marketing users report quick, helpful service; Mailchimp users frequently cite frustration and poor support reliability.
Mailchimp offers dedicated phone and priority support only with its highest Premium plan. However, general user reviews widely complain about slow or unhelpful support responses across lower paid tiers. Square Marketing customers (via Square) often praise the support team for being kind, professional, and fast with simple inquiries. Consistency is key for small businesses. Even though Mailchimp offers structured enterprise support, Square Marketing wins on overall positive user sentiment for general assistance.
Square Marketing automatically prompts customers for Google Reviews. Mailchimp does not include this crucial reputation feature natively.
Square Marketing includes automated campaigns specifically designed to solicit Google Reviews after a transaction is complete. This feature is free and critical for online reputation management. Mailchimp focuses on standard email marketing and lead generation forms. It does not possess a native workflow for collecting public reviews. For local businesses dependent on positive online trust signals, Square Marketing provides indispensable automated assistance. Mailchimp requires a separate, additional tool.
Square Marketing offers SMS as a separate, transparent subscription; Mailchimp treats SMS as a cumbersome add-on. Square sends texts for a clear base fee.
Square Marketing charges a $10 base fee plus usage for Text Message Marketing (e.g., $20 for 250 texts). This model is clear and allows flexible text volume control. Texts receive a very high 98% open rate, driving instant action. Mailchimp requires users to apply for approval and then purchase separate, recurring monthly SMS credits. Unused Mailchimp SMS credits do not roll over. Square Marketing’s text solution is simpler to subscribe to and integrate into campaign planning. Mailchimp’s SMS approach is generally more restrictive.
Mailchimp supports far larger contact lists and offers enterprise features. Square Marketing focuses on small to growing mid-sized businesses. Mailchimp is designed for global scale.
Mailchimp handles unlimited contacts on its Premium plan and offers custom tiers for 250,000+ contacts. Premium tiers include role-based access and extensive priority support sessions. Square Marketing also handles high volume, but its structure is simpler and tied to the POS system operational scale. It lacks the enterprise features like specific role-based access. If you are a marketing agency or expect massive subscriber growth, Mailchimp provides a more structured scaling path. Square Marketing is best for operational scaling tied to sales volume.
