How to block a bot that uses a slightly different email address to sign up

6 replies

There’s a bot that keeps subscribing to my emails and adding to cart. How do I block it?

It always uses the same name, but the numbers in the email are slightly changed.

One of the emails is fake52124@fakemail.com.

How do I block it?

Hello Vanni,

I hope you’re doing well ?

I’m not sure that we can “block” an email with Klaviyo. However, I would suggest you to create a segment with the condition “Properties about someone - Email contain fakemail”.

This segment will include all the bot email addresses and you’ll just have to suppress it regularly.

Hi @vanni,

If there's a uniqueness to all of these signups (i.e. always using @fakeemail) I'd add that to the segment. I'd then also add these (or 1 generic) rule to the flows so it won't trigger the flow for the people who sign up.

Using double opt-in might prevent these people from getting on the list but if you're using double opt-in I don't know if there's a way to filter these people out from not receiving confirmation emails. But double opt-in might also be a good preventative measure.

Regards,

Omar

Thank you for this reply! Adding that rule to the flows is a great idea I didn't think about! I'm also having the same issue and I set up a segment for the fakemails including the person's first name and last name which is always the same.

I will now add these rules to my flows as well!

Thank you so much Omar!
