Hello, thank you for reporting this, this has now been fixed!

Im talking about https://www.mailersend.com/contact-us when i fill all the details and click submit it just doesn't, upon inspecting and checking network section before clicking the submit, i get that error, you can test it out yourself, no contact email to send to, nothing, broken contact us page, fix it.

Hello Brainy Meadowlark! To help us narrow this down, could you share a bit more detail on what you’re seeing when you submit the “Contact us” form? Specifically: after you click Submit, do you get a “CSRF token mismatch” error every time, and does it show on the same page or only after a redirect? Also, which “Contact us” form are you using (the one on mailerlite.com, inside your MailerLite account, or a form embedded on your own website)? And is this preventing you from reaching support completely, or are other channels (like in-app chat/email) still working—plus what are you trying to contact us about (billing, account access, technical, etc.)?

why the hell is the contact us form not submitting, saying CSRF token mismatch even on private session, pissing me off...
