'Mailchimp didn't save your recent Form Block submission'

Site URL: http://www.arianamartin.com

I have a newsletter sign up form on my site linked with Mailchimp. I'm getting LOTS of emails from Squarespace titled 'Mailchimp didn't save your recent Form Block submission' due to spam/suspicious activity.

They are all clearly phishing attempts from spambots, because the names/email addresses used are suspicious (see screenshot). I used to get maybe one notification like this per week, but am now getting several per day.

Does anyone know why this is happening and how to make my form more secure?

Thanks in advance!

Did you ever get a response about this issue?

Thanks..

I am also receiving lots of emails from SS I don’t think they are spam… I actually disconnected Mailchimp then I started receiving these emails… did you ever get any response from anyone else regarding these emails? I’ve checked everywhere on site and can’t see I’ve left a Mailchimp link anywhere 🤔
