An email product block should answer a few buying questions consistently: what is it, who is it for, and what should I do next? A grid of Shopify product photos without those details can feel like a catalog dump. Choose the fields that help someone compare, then preserve that reading order when the products stack on a smaller screen.
Choose the comparison criteria
Decide what matters for this selection: size, material, use, fit, quantity, or price. Give each product the same kinds of information so readers can compare them without guessing. Avoid writing a detailed paragraph for one item and only a name for the next.
Limit the selection to products that serve the email's purpose. A gift guide may need a few distinct budgets or recipient needs. A refill campaign may need only the compatible options. More items are not automatically more helpful.
Give every option the same decision fields
Suppose the email compares two linen covers. Present size, compatible cushion dimensions, material, price context, and the main action in the same order for both. If one option includes an insert and the other does not, make that distinction explicit. Otherwise, an apparent price comparison may be comparing different packages.
Choose fields that matter to the customer, not every available catalog attribute. A refill comparison may need compatibility and quantity. A gift selection may need recipient use and delivery eligibility. The goal is to make the trade-off visible with a small amount of consistent information.
Avoid making one option look stronger simply by giving it more complete copy. If you have a preferred recommendation, explain the reason honestly, such as suitability for a particular use. Do not hide a limitation on one card while describing the other's limitations in detail.
Keep the block intact on mobile
In Sendvio, preview how the layout stacks. Each image should remain associated with its name, explanation, price, and action. If all images appear before all descriptions, simplify the structure so the reading order remains clear.
Use live text and allow long titles to wrap. Check price formatting, sale terms, and missing imagery. A fixed-height card that clips the longest product name makes the comparison less reliable precisely where the customer needs detail.
Check the reading order after the grid disappears
On a narrow screen, each option should remain a complete unit: image, name, relevant difference, price or offer context, and action. Read the stacked version from top to bottom. If the customer sees two images followed by two sets of details, the association may be unclear.
Let text grow when a name or translation wraps. Avoid using a fixed card height that cuts off the most informative description. Where desktop alignment requires compromises, prioritize the integrity of each product's content over perfectly level button baselines in one preview.
Verify the destination before sending
Open every product link and confirm availability, variant selection, and the information promised in the email. Do not imply that an accessory is included when it is only shown for styling.
Review clicks by product when that information is available, but also inspect orders and customer questions. A heavily clicked item with few purchases may be poorly explained or unavailable at the destination. Improve the decision support before concluding that the product simply needs a larger image.
Open each destination and confirm the selected variant, current availability, included items, and offer eligibility. If the page defaults to a different size or colour, the customer may believe the email comparison was wrong. A relevant link should preserve as much useful context as the supported destination allows.
Interpret product clicks carefully. The first card may attract more attention because of position, while a visually striking image may earn curiosity without suitable purchases. Compare completed actions, stock availability, and support questions before concluding that one product is inherently preferred. A good block helps a customer choose the right option; it does not merely distribute attention across a larger number of items.
