Mailchimp integration for guest contact info

The ability to send to mailchimp guest contact info from the pop up form to collect their information. In addition to sending the contact info, it would be great to also send the guide name as a tag. This would unlock a lot of email marketing capabilities.

This would be incredibly valuable not only for Mailchimp, but for other CRM and email marketing platforms as well, such as Klaviyo, HubSpot, ActiveCampaign, Salesforce, ConvertKit, and Brevo (Sendinblue).

Many hosts use different systems for guest communication and marketing automations, so expanding this beyond Mailchimp, either through additional integrations or a flexible webhook/API option, would make this feature much more powerful and usable across different tech stacks.
