Get list of mailing lists

Get a list of the basic details of all mailing lists in SendSage Studio.

URL

GET /ga/api/v2/mailing_lists

Request Parameters

This API method does not require any additional parameters.

Response

The response will be a JSON array where each element contains the following keys.

id integer	The `id` of the mailing list
name string	The name of the mailing list
d_from_email string	The default `From` email for campaigns from this mailing list
d_from_name string	The default `From` name for campaigns from this mailing list
d_reply_to string	The default `Reply-To` email address for campaigns from this mailing list
d_virtual_mta string	The name of the default Virtual MTA for campaigns from this mailing list
d_url_domain string	The default URL Domain for campaigns from this mailing list
d_speed integer	The default speed for campaigns from this mailing list
d_sender_email string	The default Sender email address for campaigns from this mailing list
d_bounce_email string	The default Bounce email address for campaigns from this mailing list.
d_seed_lists array of hashes	The default seed lists for campaigns from this mailing list. This is an array of hashes with the `id` and `name` keys.
d_autowinner_enabled boolean	The default setting for automatic winner selection on new campaigns
d_autowinner_percentage string	The default percentage that will be sent for the split-test portion of the campaign (Note: This value is returned as a string to prevent floating-point conversion errors)
d_autowinner_delay_amount integer	The default number of units of time that the campaign will wait before finishing after a split-test.
d_autowinner_delay_unit string	The default unit used in calculating the delay duration.
d_autowinner_metric string	The default metric used to decide the winner. See the “Automatic Winner Selection Metrics” table for more information.
has_format boolean	`True` if this mailing list uses the `email_format` field.
has_confirmed boolean	`True` if this mailing list uses the `confirmed` field.
custom_headers_enabled boolean	`True` if this mailing list uses custom headers. If `true`, `custom_headers` must be set.
custom_headers string	The content of the custom headers that will be added to every email sent to this mailing list.
primary_key_custom_field_id integer	The custom field id of the primary key for the mailing list. If this value is `null`, then the primary key is the subscriber’s email address.
preview_custom_field_data hash	The custom field data, see example below.
is_remote_list boolean	`True` if this mailing list uses a remote database to retrieve recipient data for campaigns.
database_connection_id integer	The primary key of the database connection to use on this mailing list.
database_connection_name integer	The name of the database connection to use on this mailing list.

Note: This value is returned as a string to prevent floating-point
conversion errors. You may send this value as an Integer, Float or String.
Posting a value with more than two decimals will cause a validation error. Be
careful because IEEE floating point can not exactly represent some decimal
values. For example 94.85 is represented as 94.85000000000001 which will cause
a validation error if used here. You may want to print to a string using two
decimal places of precision.

Preview Custom Field Data

The preview_custom_field_data key is filled with a hash.

{
  "Custom Field Name": {
    "name": "Custom Field Name",
    "type": "text",
    "value": "Bob Example"
  },
  "Next Custom Field": {
    "name": "Next Custom Field",
    "type": "select_multiple_checkboxes",
    "value": [ "Red", "Blue" ]
  }
}

Custom fields which have Preview Custom Field Data values and are not specified in
the preview_custom_field_data list, will remain with the same values. In other words:
the custom fields provided in preview_custom_field_data are merged in with the existing
Preview Custom Field Data custom fields.

Example

Note that the JSON response will not be “pretty formatted” as it is below.

Response

A successful response will return the subscriber record using the format
described in the “Get subscriber details” section of the API.

A failure will return a standard error response with an explanation of what
went wrong.

Deleting a mailing list

Deleting a mailing list is a two-step process:

Request a Delete Confirmation Code. This will generate a confirmation code
that will be valid for 2 minutes.
Send the confirmation code back to the server.

We do this because deleting a mailing list is what we consider to be a major
event. The following happens when a mailing list is deleted:

All subscribers are deleted.
All active/scheduled subscriber imports and exports are cancelled.
All active/scheduled campaigns are cancelled.
The mailing list’s database entry is marked as deleted.

From that point forward, the mailing list will no longer appear in the user interface.

URL

To request the confirmation code:

GET /ga/api/v2/mailing_lists/:mailing_list_id/delete_confirmation_code

To confirm the deletion and start the deletion process:

DELETE /ga/api/v2/mailing_lists/:mailing_list_id/confirmed/:delete_confirmation_code

Response (Request Confirmation Code)

delete_confirmation_code	The token to send back to the server to confirm deletion of the specified mailing list.
delete_confirmation_expires_at	The time at which the included token will no longer be valid.
