email - 使用外部电子邮件发送提供商有哪些优势？

Question

假设我每天发送 10k 封电子邮件，切换到 Sendgrid/Postmark/Amazon SES 等外部提供商是否有意义？为什么？

是否因为我的客户有更好的机会收到电子邮件(即他们的服务器有更好的声誉，他们更了解如何处理 SPF/DKIM 等)？

是因为我不需要担心 SMTP 服务器的配置/管理吗？

是因为带宽还是服务器负载？

是因为更好地处理退订/退回等问题吗？

是以上所有吗？ :)

我问是因为我有一个有效的系统。它不是 100% 可靠(仍有一些邮件在途中丢失)，我相信它也可以在其他方面得到改进 - 但我想知道切换到外部提供商后我可以获得哪些好处。

PS:我绝对不是垃圾邮件发送者。我正在发送一些人们要求的信息。 :)

Answer 1

All of the above!

• Do you want to spend your timefussing over your SMTP server?
• Do you want to always ensure that your SPF records and DKIM is correct?
• Do you want to spend a lot of time building your own methods of checking for delivers, - bounces, opens, and clicks?
• Do you want to spend a lot of time checking on the reputation of your IP address and making sure that it is whitelisted?
• Do you want to spend a lot of time flattening your HTML and CSS for your templates?

If you answered yes to any of these, then maybe not. Otherwise, the nominal fee you would pay for an external service is well worth having a lot more time to focus on your product rather than having to spend even a minute on your emails.
