- Add new 'Subscriptions' table on the subscriber list form that shows subs,
IP, and other data.
- Add new `meta` JSONB field to `subscriber_lsts` table.
Closes#1329.
- Change tiled UI to table UI.
- Add support for search and pagination.
- Important: This breaks the `GET /api/media` API to introduce pagination
fields. Media items are now moved into `{ data: results[] }`.
- Adds support for arbitrary file uploads with an admin setting to select allowed file extensions.
- Adds support for attaching media (files) to campaigns.
- Add support for `complaint` to the SES bounce processor.
- Add support for `hard/soft` to Sendgrid bounce processor.
- Add new bounce actions `None` and `Unsubscribe`.
- Add per type (`soft/hard/complaint`) bounce rule configuration to
admin settings UI.
- Refactor Cypress bounce tests.
- Introduces a new option on the settings UI to optionally publish the full campaign body in
public archive RSS feeds.
Closes#1033

This commit adds a new API `POST /api/tx` that sends an ad-hoc message
to a subscriber based on a pre-defined transactional template. This is
a large commit that adds the following:
- New campaign / tx template types on the UI. tx templates have an
additional subject field.
- New fields `type` and `subject` to the templates table.
- Refactor template CRUD operations and models.
- Refactor template func assignment in manager.
- Add pre-compiled template caching to manager runtime.
- Pre-compile all tx templates into memory on program boot to avoid
expensive template compilation on ad-hoc tx messages.
This is a long pending refactor. All the DB, query, CRUD, and related
logic scattered across HTTP handlers are now moved into a central
`core` package with clean, abstracted methods, decoupling HTTP
handlers from executing direct DB queries and other business logic.
eg: `core.CreateList()`, `core.GetLists()` etc.
- Remove obsolete subscriber methods.
- Move optin hook queries to core.
- Move campaign methods to `core`.
- Move all campaign methods to `core`.
- Move public page functions to `core`.
- Move all template functions to `core`.
- Move media and settings function to `core`.
- Move handler middleware functions to `core`.
- Move all bounce functions to `core`.
- Move all dashboard functions to `core`.
- Fix GetLists() not honouring type
- Fix unwrapped JSON responses.
- Clean up obsolete pre-core util function.
- Replace SQL array null check with cardinality check.
- Fix missing validations in `core` queries.
- Remove superfluous deps on internal `subimporter`.
- Add dashboard functions to `core`.
- Fix broken domain ban check.
- Fix broken subscriber check middleware.
- Remove redundant error handling.
- Remove obsolete functions.
- Remove obsolete structs.
- Remove obsolete queries and DB functions.
- Document the `core` package.
It was observed that the next-campaign-subscribers query on an instance
with ~9 million subscribers had slowed down significantly. Fetching
a batch of 5k subscribers was taking around ~25 seconds.
After multiple hours of debugging and trial and errors, it turned out
that Postgres was doing very poor query planning on JOINs with CTEs
because of the dynamic cardinality of some CTEs (even with just 1 row).
Afer rewriting the query and adding a hack to overcome the CTE
cardinality issue, the same query now takes a few milliseconds,
a speed up of several orders of magnitude.
- Change `query-lists` query to aggregate the subscriber count by
status (confirmed, unsubscribed etc.) and expose them under a new
`subscriber_statuses: {}` field in the `GET /lists` API.
- Display the statuses and counts in the lists table on the UI.
Closes#616
The analytics page showed non-unique counts for views and clicks which
was misleading and source of confusion: #522, #561, #571, #676, #680
This commit changes this behaviour to pull unique views and clicks when
individual subscriber tracking is turned on in settings, and non-unique
counts when it is turned off (as `subscriber_id` in `campaign_views`
and `link_clicks` will be NULL, rendering unique queries dysfunctional).
This commit changes the stats SQL queries to use string interpolation
to either to SELECT `*` or `DISTINCT subscriber_id` on app boot based
on the setting in the DB. This involves significant changes to how
queries are read and prepared on init.
- Refactor `initQueries()` to `readQueries()` and `prepareQueries()`.
- Read queries first before preparing.
- Load settings from the DB using the read settings query.
- Prepare queries next. Use the privacy setting from the DB to apply
string interpolation to the analytics queries to pull
unique/non-unique before preparing the queries.
On the UI:
- Show a note on the analytics page about unique/non-unique counts.
- Hide the % donut charts on the analytics page in non-unique mode.
Closes#676, closes#680
- Add new `headers[]` column to the campain table.
- Add new headers box to the campaign UI that takes a JSON array of
custom headers like the headers on the SMTP settings UI.
- Headers are added to e-mails and messenger postback webhooks.
- Add cypress tests.
Closes#514.
- Add route /lists/:id URI to load subscriber edit modal.
- Make list name open the edit popup to be consistent with all other
table views.

(~10x speed bump on a setup of 7mn subscribers and 80mn views)
- Refactor get subscriber queries.
(~10x speed bump on 7mn subscribers)
- Make subscriber UI issue an equality query for email seach strings.
- Blocklist or unsubscribe subscribers based on a bounce threshold
- Add /bounces UI for viewing bounces and in the subscriber view
- Add settings UI for managing bounce settings
- Add support for scanning POP3 bounce mailboxes
- Add a generic webhook for posting custom bounces at /webhooks/bounce
- Add SES bounce webhook support at /webhooks/services/ses
- Add Sendgrid bounce webhook support at /webhooks/services/sendgrid
