On June 3, I received more than 49,000 bulk signups. The only information I see about bulk removals is to setup up tracking of who hasn’t opened an email in the past 90 days, but I don’t want to wait 90 days to fix this. How can I bulk remove them?

For the 49,000 today, ActiveCampaign support may be able to help you do all at once. I’d ask them first. The key is being able to isolate / identify them so you don’t get rid of good contacts with these bad ones.

In the past you could run all of them through an automation and unsubscribe them from all. You could then filter your contacts view so you wouldn’t see them.  

To truly get rid / delete them so you don’t see them in your account, you’d likely need someone to use the API to do it.

 

For anyone reading this in future:

You’l want to identify how they got in to stop this in future.

Did they come via API or form?

You can prevent contacts from getting in using a tool like spamkill on forms, or if they somehow get in, if you have an email validation tool integrated, it would catch them then.

Thanks for your response! Do you have any idea how I can reach ActiveCampaign support? The chat and phone are only AI and I’m not sure how to reach a human. I even tried the sales line, but that just goes directly to voicemail.

 

I wish I knew how they did it. I have a signup form on my website (Wordpress), with a captcha. It’s not super secure, but until now it’s been fine. And now I can’t sign up anyone with that form, which is puzzling.

try the gear in top right corner

click it, look for view support tickets.

click that and see if you can get help that way via that chat.

Is your account relatively new or old (is before 2025)?

Unfortunately, “view support tickets” just brings up a blank AI chat box. I created my account around 2018 or so - it’s definitely not new.
