Loved [OTHER_WRITER]'s article!
Hey [NAME],
I just noticed that you published a post from [OTHER_WRITER] and saw that it did really well for you.
That's awesome, glad that one performed so well.
I figured since that article was able to generate those kind of views, you might want to check out this article I wrote that covers a very similar angle. It tackles [AREA]. I really thinks this is something that the [COMPANY] audience will love and I know it'll perform well.
I've attached it for you, or you can check it out live on [BLOG_LINK]. If it's a fit, I'd be glad to have you republish it. :)
Let me know what you think and have a great week.
