Think you're mixing apples with oranges with a lot of your analysis. For example, though I might be wrong, when you state "double opt-in verification" this appears to reference an email sub verification, not an account verification. While the tech is related, the stats and user behavior chain is not in my experience; meaning there is no correlation at all, and to say there is in my opinion is dangerous. The reference to the opt-in after your crowdfunding campaign also has no correlation to a transactional email auto sent seconds after an accounts verification request. Any thoughts?

@blunders You're right, "double opt-in" wasn't the best choice of words. But I also explain in my answer that email marketing is different - but I believe there is a correlation, and not as different as one might think. As for the crowdfunding customers - that is incredibly related. I'm talking about people that signed up on my site and either did or didn't click the link in their email to confirm the account. Exactly what the original question was about. I only added the fact that it was after a crowdfunding campaign to add some context that these are already paying customers.

@blunders - I'll edit out "opt-in" but other than that there is only one sentence giving some stats about email marketing and one sentence explaining that it's not a perfect correlation - I'll leave those there as I don't feel they take away from the overall answer even if you don't think there is any correlation at all.

Thanks, reviewed your edits, though the edits just appear to be an attempt to hide the bias for your analysis, which in my opinion is not based on facts that are relevant. For example, in my opinion, it's still clear that your talking about a sub verification, not an account verification; for example, "subscribe to a mailing list" is still present in your answer, and again, unrelated to the topic. Not looking to get into a debate, and grateful that you took the time to consider my thoughts on the topic; really, meaning that these thoughts are my own, and very possible I am wrong.

@blunders I realize that phrase is still there - I explained why I left it and again that is one sentence followed by a second sentence explaining it isn't a perfect correlation. The crowdfunding thing has NOTHING to do with email subscriptions - it is talking ONLY of account verification. As are the other several paragraphs. Other than ONE SENTENCE can you point out anything in the rest of the answer that shows my analysis is skewed toward email subscriptions? Because I'm honestly baffled by why it is "clear" that's what I'm talking about when it ISN'T what I was talking about.

Ironically, one of the things I feel I've somewhat failed at is not making the time to set up a mailing list for the business that I crowdfunded - so I have less experience to talk about it from that angle anyway. Certainly wasn't what I had in mind when I wrote this answer.

Okay, so this issue is that sub list averages are more like 50% plus when it comes to activation abandonment; meaning there is no correlation between email and account activation rates in my experience. Also, the way to handle this is different in each case too.

@blunders Once again I repeat - I only discuss email subscriptions in 2 sentences in my several paragraph long answer. And one of those 2 sentences is specifically to state that there is a difference between email subscription and verifying an account signup. You're making a HUGE issue about 2 relatively insignificant sentences. You're allowed to disagree on how much of a correlation there is, that's fine, but I still can't comprehend how my whole answer is invalidated by 2 sentences. (Also not sure what that 50% abandonment number is - that seems REALLY high for either type of verification)

When you say 50% is high, are you comparing all submissions that are sent to emails that are active after completing the the validation process? Meaning even clicking the validation link is meaningless, what matters is the email is active after the validation process. Also, please let me know if it's okay to delete my comments below the question, the link to this chat should work; happy to leave them there though too.
