I would find it quite annoying to get any of those emails.

When I give you my email, it's not because I actually want to hear from you; it's because you've made it the only — or the least shady — way to sign up. I do not want to hear from you or answer your questions, especially before I've decided that I like your product and care about it.

So any such email I immediately mark as junk, and the fact that you sent it to me will go the "cons" column when evaluating your product vs the competitors.

Life must be really hard if you get to that point where a welcome email coming from a service you signed up for a trial is so "annoying" that you "immediately mark as junk".
