- More options how to send test emails.
- Fixed problems with pausing a campaign (#593)
- Started rework of transactional sender of templates (#606), however this contains functionality regression at the moment because it does not interpret templates as HBS. It needs HBS option for templates as described in https://github.com/Mailtrain-org/mailtrain/issues/611#issuecomment-502345227
TODO:
- detect sending errors connected to not able to contact the mailer and pause/retry campaing and queued sending - don't mark the recipients as BOUNCED
- add FAILED campaign state and fall into it if sending to campaign consistently fails (i.e. the error with sending is not temporary)
- if the same happends for queued email, delete the message
The namespace filter in campaigns was dropped (i.e. "Work with campaign's namespace"). Instead, we need a universal solution. For instance a namespace slector somewhere in the top-right corner, which should apply to everything (not just campaigns).
Nevertheless, I kept the ...-by-namespace rest endpoints and related functions in models because they will be useful for implementing the universal namespace selection feature.
