Subscribers

Subscribers are the main way you collect email addresses and recipients on Buttondown. They're what you see on your subscribers page.

The subscriber object

A subscriber looks like this:

{
    "creation_date": "2019-08-24T14:15:22Z",
    "email": "user@example.com",
    "id": "497f6eca-6276-4993-bfeb-53cbbbba6f08",
    "metadata": {
        "foo": "bar"
    },
    "notes": "",
    "referrer_url": "http://jmduke.com",
    "secondary_id": 3,
    "source": "api",
    "subscriber_type": "regular",
    "tags": [],
    "utm_campaign": "",

Creating a new subscriber

POST → https://api.buttondown.email/v1/subscribers

If Buttondown cannot create a new subscriber with the email address you've provided, there are a few likely reasons why. They're enumerated below:

  • A subscriber with that email has already been unsubscribed.
  • That email address (justin@gmail.com) is already subscribed.
  • That email address (justin@gmail.com) is already subscribed, but has not confirmed their email.
  • That email address (justin@gmail.com) is already subscribed, but has not provided payment.
