Please please can you integrate automatically with Omnisend like you do with Mailchimp?
Otherwise its totally pointless for me to use your contact forms for business purposes.
Thanks in advance! 
Hi there and welcome aboard @Pablo1 
I agree that it would be awesome to add Omnisend integration to our Forms app. We’ll try to consider this option in our future updates.
However, there is a workaround! You can connect your widget to Omnisend using Zapier integration.
Just in case, here is an article explaining everything in more detail - How to integrate your Form widget with Zapier - Elfsight Help Center
