Argh, stop with the popups for my email address while I’m trying to read your blog! How can I enjoy your content when I’m interrupted with these? It does your site, or the prospects for getting newsletter subscriptions, no credit.
I’m more than happy to consider subscribing to a newsletter if I think the content you write is worth it. So by all means, offer a chance to do so and the end, or even in the middle, of the article. But don’t show a popup obstructing the very content I’m trying to read and that you want me to consume more of. It gives me a sense of desperation and lack of empathy for the readers you’re trying to attract.
Note to self: never do this yourself.
