Mailchimp intergration to an other mailing list provider


All my forms on my website are currently directing to Mailchimp but my company is changing the email marketing automation provider and I would like to ealisy change all forms redirection. Is there a way to do it in one place ?
We have several forms and if I do it manually I think I will miss some of them.

Thank you in advance for your help

I don’t know of a universal way to do this. Are you using this method to send to MailChimp?

Your new provider will likely have their own integration steps.

Yes, it was done that way.

Thank for the input. Hopefully my task will not be too tedious
