To mint NFTs triggered by Mailchimp campaign sends:
1. Create an NMKR account for NFT minting on Cardano.
2. Sign up for a Zapier account if you don't have one.
3. Start a new Zap in Zapier.
4. Select Mailchimp as the trigger app and choose the trigger event (e.g., 'Campaign Sent').
5. Connect your Mailchimp account to Zapier.
6. Set up the NMKR action in Zapier, linking it to your NMKR account.
7. Configure the NFT minting parameters, using Mailchimp campaign data for NFT metadata.
8. Test and activate the Zap.
This will automatically mint an NFT on Cardano each time you send out a Mailchimp campaign.
