Improving Mautic's bounce management

Please take a look at the full proposal on this link: https://docs.google.com/document/d/1FvzEtBmp-7kXjfIAnBo8ntFtWandzW3pdlfcmBVnR4M/edit.

Mautic processing of email webhooks from Omnivery, Mailgun and similar providers is a bit limited due to insufficient underlying model where we store information coming from webhooks. This proposal aims to add ability to the Mautic core in a way so that transport plugins can leverage them and map it more precisely to the Mautic core model.

Proposed Solution

For the problem described above the developer (@Matic Zagmajster) is suggesting that we add a complaint flag into the DNC entity so transport plugins can use it when the provider (Omnivery, Mailgun, etc.) suggests so.

We would also like to introduce soft bounces into Mautic core in a way so that we still send to contacts that soft bounces, but if the soft bounce happens multiple times that translates to the DNC entity for that lead with a hard bounced flag.

How many times contact soft bounces consecutively before it translates to hard bounced is configurable with the setting in Configuration -> Email Settings.

We introduce soft bounce categories so that transport plugins can categorize and we can display that data to the end user.

We would add the following filters on segments: filter for DNC complaint reason, soft bounce filter and soft bounce of specific category.

We would like to show some more statistics about bounced, soft bounced and complaint contacts on the email list page.

We would like to show the count of soft bounces & complaints on the contact page. Also show how many soft bounces until the hard bounce for the given contact.

Show count of soft bounces & complaints on email list view.
