If you notice that spam signups have started around a certain time, create a segment based on the characteristics of spam email addresses. If the email address is a name, and the first and last names provided don't match the email address, it could be a spam signup. Spambots don't always match audience data to the email address. First and last name fields are filled, but don't match the name in the email address.

A strange email address, combined with these other characteristics, can suggest spam. This can be hard to determine, but sometimes addresses just look fake.

The email address is a name, but doesn't look like a real name.

Look for these characteristics that are typical of spam signups. If you have a lot of email addresses in your audience, it can be hard to tell which ones might be spam. Those addresses never make it to your audience. Forms submitted with the extra fields filled in are immediately flagged as spam and discarded. On all of our forms, we include some fake fields called honeypot fields that aren’t visible to humans. This type of throttling is effective in preventing these kind of attacks. That means that if the same email address is added to multiple audiences in a short period of time, we'll block it from being added to any other audiences for another 24 hours. They hope that all the new emails in the target’s inbox will overwhelm them and distract them from malicious activity.īecause we know about this tactic, we can throttle new signups. Sometimes, when an abuser attempts to takeover an account, they'll sign their target up for a several email newsletters at once.

Since spambots can’t access the checkbox, they can’t join your audience. This tool requires subscribers to check a protected reCAPTCHA box to complete the signup process. If you use an embedded or pop-up form, reCAPTCHA can be enabled on the Audience name and defaults page. ReCAPTCHA is our best line of defense against spambot signups, and we automatically add it to all Mailchimp hosted forms. Here are a few techniques we use and enable for our customers. We also continually analyze and improve our spam prevention systems and technologies to stay ahead of new abuse tactics.

Mailchimp signup forms aren't immune to this activity, but we have a few tools in place that help protect our users and their customers from bad data.
