This commit removes the Go html2text lib that would automatically
convert all HTML messages to plaintext and add them as the alt
text body to outgoing e-mails. This lib also had memory leak
issues with certain kinds of HTML templates.
A new UI field for optionally adding an alt plaintext body to
a campaign is added. On enabling, it converts the HTML message in
the campaign editor into plaintext (using the textversionjs lib).
This introduces breaking changes in the campaigns table schema,
model, and template compilation.
The default language (en) is loaded first and the selected
language is loaded on top of it so that missing translation keys
in the selected language will have the original English strings
available on the UI.
This was a ridiculous miss, where on first time installation, the
well designed default e-mail template was never installed in the
DB! I never spotted this because my local dev setup, and
surprisingly, nobody ever complained that the default campaign
template was a blank slate with no styles.
Certain SMTP hosts limit the total number of messages that can be
sent within a window, for instance, X / 24 hours. The concurrency
and message rate controls can only limit that to a max of
1 messages / second, without a global cap.
This commit introduces a simple sliding window rate limit feature
that counts the number of messages sent in a specific window, and
upon reaching that limit, waits for the window to reset before
any more messages are pushed out globally across any number of
campaigns.

The link_clicks.link_id table was NULLable incorrectly. Links that
do not exist should not register a tracking entry. Fix the query
and also update the schema + migration (breaking table change).
A new toggle switch in Settings -> Privacy, which is off by
default, allows campaign views (pixel) and link clicks to function
without registering the subscriber ID against view and click
events, anonymising tracking. When off, the subscriber UUIDs in
view and link tracking URLs are removed, anonymising subscriber
information from HTTP logs as well.
According to [RFC6532](https://tools.ietf.org/html/rfc6532) unicode characters are supported in email address but the in-built custom regex was only validating ASCII characters.
This is a major feature that builds upon the `Messenger` interface
that has been in listmonk since its inception (with SMTP as the only
messenger). This commit introduces a new Messenger implementation, an
HTTP "postback", that can post campaign messages as a standard JSON
payload to arbitrary HTTP servers. These servers can in turn push them
to FCM, SMS, or any or any such upstream, enabling listmonk to be a
generic campaign messenger for any type of communication, not just
e-mails.
Postback HTTP endpoints can be defined in settings and they can be
selected on campaigns.
This removes the Nginx dependency for protecting admin pages.
BasicAuth is configured in config.toml. This is a "temporary"
setup until a full fledged auth mechanism is added.
- Add missing `app.root_url` key in migration.
- Register `/settings` handler in the backend.
- Add dummy dots in secret fields on the UI for visibility.
- On boot, the app now checks if the DB version matches its
expected version and refuses to start if there are pending
migrations to be run.
- The new `--upgrade` flag runs data migrations from the last
recorded migration (in the settings table) to the latest one
in the binary.
- Migrations are DB/arbitrary logic functions in .go files in
internal/migrations.
- All migration functions are idempotent.
- Added as a setting in the settings UI.
- Refactor Messenger.Push() method to accept messenger.Message{}
instead of a growing number of positional arguments.
This is a major breaking change that moves away from having the
entire app configuration in external TOML files to settings being
in the database with a UI to update them dynamically.
The app loads all config into memory (app settings, SMTP conf)
on boot. "Hot" replacing them is complex and it's a fair tradeoff
to instead just restart the application as it is practically
instant.
A new `settings` table stores arbitrary string keys with a JSONB
value field which happens to support arbitrary types. After every
settings update, the app gracefully releases all resources
(HTTP server, DB pool, SMTP pool etc.) and restarts itself,
occupying the same PID. If there are any running campaigns, the
auto-restart doesn't happen and the user is prompted to invoke
it manually with a one-click button once all running campaigns
have been paused.
- Fix path related issues in filesystem and S3.
- Add checks for S3 "/" path prefix.
- Add support for custom S3 domain names.
- Remove obsolete `width` and `height` columns from media table (breaking)
- Add `provider` field to media table (breaking)
- Refactor campaign.Message into campaign.Message and
campaign.CampaignMessage
- Remove ad-hoc goroutines (flawed approach) that were used to push
admin and optin notifications.
- Provision for largscale pushing of ad-hoc, non-campaign messages
such as transactional messages (in the future).
