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.

Those victories included deeply personal stories, like a father in India who won his petition to get medical care for his dying 12-year-old son and big, systemic victories that will impact millions of people, like a teenager from Mississippi who convinced Coca-Cola and Pepsi to remove a potentially harmful chemical from all of their beverages.

  1. Hello,

    Thank you for posting this. I will reach out to and raise the visibility of them hitting your spamtraps. I can follow up on how we plan to address this.


    • Great, Ryan. I also heard from Paul Kincaid-Smith in another forum, so it sounds like Sendgrid is doing what it should do.

      I’ve also heard from a number of people who signed a single petition, however, and got bombarded with a whole lot of email, much of it not relevant to the petition they signed. I’m sure has legal language in the small print when you sign a petition that lets them send email, but the volume and subjects of the email they send are not what many users expect to receive. That’s not technically spam, but it *is* a bad practice and is alienating people.

  2. Thanks for the heads up on this. I am working on tightening up our sign-up workflow – will look at reviewing our sunset policy also.

    • Hi, Alice. I didn’t realize that ReturnPath was involved with Thank you for the response. might also want to look at how it sets expectations for email and the volumes of email that it sends to users. I’ve seen a lot of response to this blog, more than to most of my blogs here. People who have signed petitions tell me that they get bombarded with email, much of it not relevant to the petitions that they signed. That sort of thing probably isn’t technically spam, but it also alienates the people that they want to keep around.

      • I hear you. have brought me on board to pull their email programme into shape – there’s definitely a lot of work to do. Expectation setting is top of my list at the moment. I really appreciate your feedback – I hope you will notice positive results very soon!
