You can trigger an autoresponder when a new address is added via the API. For example, if you have an online shopping cart that adds new customers to your mailing list at checkout (via the API), you could use this trigger to send them follow-up emails, promotional offers, etc.
This trigger can be especially powerful when paired with our Zapier integration. Zapier connects hundreds of online apps to Direct Mail, allowing you to create automated workflows. Addresses added to Direct Mail via Zapier will cause this trigger to fire.
If you use the API trigger, you will need to select which address groups Direct Mail should monitor for new addresses added via the API.
