Hi @Akselpd,

Sorry to hear you’re having to deal with this headache.

Perhaps the following ideas were included when you mentioned you’re using filters in segments or using list clean-up, but I’d also consider creating a segment using the fakemail criteria to gather all of the bot emails. Something like the following: email contains  > @fakemail.com. You can separate the fake email domains using “OR” to scoop up as many of the fake domains possible. Follow this up by bulk suppressing the segment. Here's an article with step-by-step instructions on How to Bulk Delete or Suppress Email Contacts in Klaviyo.
 
Also, to prevent fake emails from entering your flows in the future, consider adding a flow filter to each of your flows with the exclusion criteria: properties about someone: email doesn't contain @fakemail.com. Make sure you’re using an “AND” separator to separate multiple fake email domains i.e. email doesn’t contain fake domain X AND email doesn’t contain fake email Y etc. That will prevent potential deliverability issues of bounced emails from your flows for fake email addresses. 

 
I hope that’s a helpful start. In addition to this, I recommend continuing to work with support on strategies and solutions - they’ll be able to have a closer look at the specific emails and provide a more tailored segment definition to help mitigate the impact of these fake profiles. It would also be great to hear if anyone in the community has any alternative strategies we haven’t thought of yet!

Thanks for being a community member. 

Hi @Akselpd,

I’m encountering this right now and wanted to see if you were able to resolve it?

Thanks!

Hi - just a quick question on this solution, would it still work if the fake email addresses are all @gmail.com I assume it won’t catch them, but I would like to find a way to fix my issue, which is mainly with fake gmail accounts as it has plummeted our welcome series open rates. 

Also, does anyone have examples of amazing double opt in email flows, from my experience signing up, very few companies use the double opt in, and the few that do, don’t have a great appearance. 

Hey all! This an industry problem we talk a lot about here in the community. The more sophisticated bots get, the harder managing them becomes. Klaviyo is actively working on solutions to mitigate bot activity. In the meantime, here are other threads with solutions:

• Suspicious SPAM adresses signing up
• Spam email addersses being add to my audience
• Getting TONS of spam bot email signups
• HELP! Spam attack? More sign-ups than users…

TL;DR: Enable double opt-in, clean your list often by looking for patterns in the bot addresses, set up reCAPTCHAs on your signup forms, increase your site’s security with 3rd party bot prevention tools.
