SEO推广关键词难做？谷歌竞价广告推广的正确方式
Is SEO keyword ranking difficult? The right way to do Google Ads promotion
许多外贸业务员都在询问："不会封号的外贸邮箱群发软件/工具/平台/EDM有吗？"这个问题反映了企业邮箱被限制或封号的普遍困扰。
Many foreign trade salespeople ask: "Are there any foreign trade email blasting software/tools/platforms/EDM that won't get banned?" This question reflects the common problem of corporate email restrictions or bans.
残酷的真相：没有完全不会封号的邮件群发平台！如果某个平台声称"永不封号"，实际上意味着它的发信效果无法保证。
The harsh truth: There is no completely ban-proof email blasting platform! If a platform claims "never banned", it actually means its delivery effectiveness cannot be guaranteed.
为什么会被封号？
Why do accounts get banned?
1. 无效邮箱率过高：当长期发信过程中无效邮箱超过5%，邮件服务商就会将发信服务器IP和域名列入黑名单。
1. High invalid email rate: When invalid emails exceed 5% during long-term sending, email providers will blacklist the sending server IP and domain.
2. 客户投诉过多：如果邮件内容与客户需求不相关，投诉率超过0.05%就会导致封号。
2. Excessive complaints: If email content is irrelevant to customer needs, a complaint rate exceeding 0.05% will lead to bans.
