Campaigns in thanks.io automatically run for people in a mailing list. For campaigns to send automatically, we need to automatically deposit people into mailing lists. This can be automated very easily using Zapier.
Visit this link to get to the Zapier integrations page, and choose your app.
You'll want to use the 'Add Recipient' thanks.io action to add your recipient's data into your campaign's mailing list.
That's it! Your campaign in thanks.io will take it from there.
