All you have to do is create the resources to replace those broken and outdated links and it's time to send an email!
Hello (backlink buddy),
I was looking for information on the topic (topic) and came across your excellent blog post, (title).
The points you made were truly fantastic. However, I noticed that this post has an outbound link to female database (website). I read through this reference and found that many of the points made therein are quite outdated. (Or: I tried following the link, but it seems this website is no longer online.)
I recently published this article, which actually addresses the same topic, (title). Here's the link: (insert link)
(Add a short sentence summarizing the highlights of your article.)
Anyway, thanks for the information about (the topic of the originally mentioned blog post)!
