I struggled with this for years. I then realized, it isn't spam. The user can opt out at any moment and they are pulled off the marketing list. You legally always need to make that an option. Also it was over 10 days, so kind of longer than a week ;) But a transnational email is expected on signup, that is how you activate your account and verify your email address. Then the personal welcome was always a VERY highly opened and responded to email. I would do my best to keep up with the questions. The third email wasn't always sent, only if they hadn't used the product, and it was assumed they needed help. And the last email was a coupon, and who doesn't like coupons!?
