Omnisend, just like Mailchimp, is a very popular email/sms marketing tool.
@user2618 thanks a lot for your suggestion, and welcome to the Elfsight Community!
Although we don’t have a direct integration with Omnisend, we’ve recently introduced Zapier integration which could help you here
Anyways, if there’s any news regarding the direct integration, I’ll keep you updated here.
Thank you very much for your help!
