什么是电子邮件种子名单？

电子邮件种子列表是一个测试电子邮件地址的列表，其目的是监测邮件发送时的着陆点。这些列表通常包含主要供应商的测试地址，如Gmail、雅虎、AOL、Orange.fr和许多其他ISP域名。

Senders can add seed lists to their upcoming campaigns to measure inbox placement at various providers. A seed list allows you to test where an email will land across different email clients and devices as well as see how your campaigns are rendered in different browsers and email clients.

电子邮件种子列表的挑战

近年来，许多主要 ISP（如 Gmail、Verizon Media（AOL、Yahoo、Verizon）和 Outlook 域）已开始将参与度作为inbox 投放的考虑因素。因此，发件人不一定只能依靠种子列表的结果来确定inbox 的位置，因为从种子测试中获得的洞察力可能无法全面反映电子邮件营销活动的成功程度。

Because the email addresses in seed lists are test accounts, there is no engagement associated with them. As a result, ISPs see these accounts as inactive. Emailing to an inactive account can affect a sender’s IP/ domain reputation and can result in heavy spam foldering. This can also add another layer of complexity when 热身 new IPs. Since Gmail expects senders to 从真正的低量开始 during the first couple of weeks of ramping up email sending, hitting a relatively large number of inactive addresses will complicate building a 良好的声誉 on new IPs. We always recommend that our customers send traffic to their most engaged users for the first 4 weeks of a ramp up.

我们的建议是在热身阶段避免使用种子名单。如果在与互联网服务提供商建立了良好的声誉后才决定使用种子名单，则应将种子名单作为决定campaigns 是否成功的众多因素之一。

Monitoring 打开率 can provide more accurate data points when determining whether your emails are making it into the inbox. Of course, the open rate may vary based on the type of traffic (welcome, 交易性的, marketing) but the average open rate for Marketing emails is about 20%, this rate is higher for transactional traffic or triggered messages.
