Yes, this website will spam you with multiple emails a day. However, in general I usually read at least one piece from each email. There is always something on there that piques my interest, whether they are inspirational quotes, tips on de-stressing, or activities to lift your spirits. Even if you aren't a religious person, I still think you can gain something out of these quick slideshows the website puts together.
It's sort of like reading a "Jesus loves you" bumper sticker. Even if you don't believe in Jesus Christ, you still think, "Well, that's a nice sentiment." That's sort of what this website and its emails are like.
