We’ve seen double-opt in rates within Mailchimp slip to 39%. This means 61% of people start but do not finish the double opt-in process.
We see that in the confirmation failure rates, which are generally in the 20% to 40% range. Those aren’t just numbers. Those are lots of genuinely interested people who will be disappointed when they don’t receive your emails.
