最佳实践
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
借助电子邮件注释,您可以添加图片、优惠、截止日期和其他优惠信息,让电子邮件更具吸引力。通过使用优质图片和最相关的信息,您的电子邮件更有可能在 Gmail“推广”标签页中被查看和点击。*
本部分概述了为电子邮件添加注释的最佳实践。
图片
- 避免仅限文本。此空间旨在突出显示宣传电子邮件的视觉元素。为了提高效果,请尝试使用产品图片或展现生活方式的图片。
- 剪裁得当。系统会自动对图片进行居中裁剪。支持的宽高比为 4:5、1:1、1.91:1。
- 避免重复使用图片。使用独特的图片,让您的宣传电子邮件保持新鲜感和吸引力。重复使用同一张图片的电子邮件可能会被用户视为重复邮件而忽略。
- 图片网址应使用 HTTPS(而非 HTTP)。
特惠徽章
突出显示促销活动的特色,例如“八折优惠”或“免运费”。
- 内容要具体。确定促销活动的详细信息,例如折扣百分比或促销代码。
- 不要使用冗长的句子。避免在特惠徽章中使用超过 4 个字词或完整句子,因为徽章空间会与主题行竞争。
徽标网址
使用 HTTPS(而非 HTTP)网址。此徽标选择仅显示在电子邮件预览中。
折扣代码
只有在电子邮件中看到折扣代码时,才可使用该代码。请勿将此空间另作他用,因为文本前面始终显示“代码”。
到期日期
使用此功能后,电子邮件将有两次机会在套装顶部进行预览:一次是在首次发送时,另一次是在优惠到期前 3 天内。
请勿在注释中留下过期日期,因为系统会将其解读为旧优惠,并且电子邮件不会填充到套装中。
指定时间和时区(例如“2018-12-30T23:59:59-0700
”)。如需详细了解日期格式,请参阅设置日期和时间的格式。
* 系统会根据多种因素自动对电子邮件进行分组。

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."]]
