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.
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.
- antd+react was resulting in extremely clunky and unreadable
spaghetti frontend code (primarily due to how antd is).
- Buefy is lighter by an order of magnitude, has excellent
responsive views (especially tables) and usability.
- Vue's templating produces far more readable template code.
- Campaigns now have a `type` property (regular, opt-in)
- Opt-in campaigns work for double opt-in lists and e-mail
subscribers who haven't confirmed their subscriptions.
- Lists UI shows a 'Send opt-in campaign' optin that
automatically creates an opt-in campaign for the list
with a default message body that can be tweaked before
sending the campaign.
- Primary usecase is to send opt-in campaigns to subscribers
who are added via bulk import.
This is a breaking change. Adds a new Postgres enum type
`campaign_type` and a new column `type` to the campaigns table.
- Lists can now be marked as single | double optin.
- Insert subscribers to double opt-in lists send out a
confirmation e-mail to the subscriber with a confirmation link.
- Add `{{ OptinURL }}` to template functions.
This is a breaking change. Adds a new field 'optin' to the lists
table and changes how campaigns behave. Campaigns on double opt-in
lists exclude subscribers who haven't explicitly confirmed subscriptions.
Changes the structure and behaviour of how notification e-mail routines,
including notif email template compilation, notification callbacks for
campaign and bulk import completions.
- Better template function shorthand substitution.
- Make `UnsubscribeURL` a function consitent with TrackLink.
This is a breaking change that makes the old `.UnsubscrbeURL`
obsolete.
This commit introduces a `blobstore` package and refactors the existing
upload mechanism. Upload is now handled by `providers` and the two
bundled providers are `S3` and `Filesystem`. `app.Blobstore` initialises
the correct provider based on the configuration and handles `Put`,
`Delete` and `Get` operations.
- Simplify campaigns querying to separate statistics gather into
a separate query for lazy loading.
- Simplify subscribers query to separate list fetching into
a separate query for lazy loading.
Quill link dialog (righly) escapes quotes in URL values there by breaking the
TrackLink() template function. That is, {{ TrackLink "https://listmonk.app" }}
when inserted using the Quill link dialog would become
{{ TrackLink "https://listmonk.app" }}. A simplework around is to
add support to backticks so that the template parser works with
{{ TrackLink `https://listmonk.app` }}
- Add a name / e-mail "quicksearch" input to the UI
- Implement row selection and aggregation at table level and a "select all" that selects all rows at the query level
- On selected subscribers, add bulk list management (add / remove / unsubscribe), blacklist, and delete
- Add notifications for campaign state change
- Add notifications for import state change
