By using high-quality\nimages and the most relevant information, your emails are more likely to be\nviewed and clicked on within the Gmail Promotions tab.[\\*](#footnote)\n\nThis section outlines best practices for annotating your email messages.\n\nImages\n------\n\n- Avoid text only. This space was designed to highlight the visual components of your promotional email. To improve performance, try using product or lifestyle images.\n- Crop well. Images are center-cropped automatically. The supported aspect ratios are 4:5, 1:1, 1.91:1.\n- Avoid reusing images. Keep your promotional email fresh and engaging by using unique images. Email messages that reuse the same image may be disregarded as duplicates by users.\n- Use HTTPS (not HTTP) for image URLs.\n\nDeal badge\n----------\n\nHighlight the features of your promotion, such as \"20% off\" or \"Free Shipping.\"\n\n- **Be specific**. Identify the details of your promotion, such as the discount percentage or promo code.\n- **Don't use run-on sentences**. Avoid using more than 4 words or full sentences in deal badge, as the badge space competes with your subject line.\n\nLogo URL\n--------\n\nUse an HTTPS (not HTTP) URL. This logo selection only shows in the\nemail preview.\n\nDiscount code\n-------------\n\nOnly use a discount code if you have it featured in the email. Don't\nrepurpose this space, as it always says \"Code\" before the text.\n\nExpiration date\n---------------\n\n- Using this feature allows an email two opportunities to preview at the top in\n a bundle: once when it is first sent and again within 3 days of the offer\n expiring.\n\n- Don't leave an expired date in the annotation, as it will be read as an old\n offer and the email will not populate into a bundle.\n\n- Specify the time and time zone (for example, \"`2018-12-30T23:59:59-0700`\").\n For more information date formatting, see\n [Format date and time](https://support.google.com/merchants/answer/7055760).\n\n\n\\* Emails are grouped automatically based on a number of factors."]]
