Lots of Typoed Signups, Never Detected

Yesterday petition website emailed updates or confirmations to almost four dozen of my spamtraps, every single one of them a likely typo of a real email address that probably did sign up for this email. has been emailing many of these email addresses for months without once noticing that nobody is responding to their email. The ESP is Sendgrid.

If is emailing my typotraps in this quantity, I wonder how many real email addresses they are bombarding that never signed a petition or asked for their email. A bunch, is my guess.
