Probem described in issue.
In the old MEGA flow:
- The `email_verification_required` check is now repeated inside the job
In the new email service flow:
- The `email_verification_required` is now checked (didn't happen
before)
- When generating the email batch recipients, we only include members
that were created before the email was created. That way it is
impossible to avoid limit checks by inserting new members between
creating an email and sending an email.
- We don't need to repeat the check inside the job because of the above
changes
Improved handling of large imports:
- When checking `email_verification_required`, we now also check if the
import threshold is reached (a new method is introduced in
vertificationTrigger specifically for this usage). If it is, we start
the verification progress. This is required for long running imports
that only check the verification threshold at the very end.
- This change increases the concurrency of fastq to 3 (refs
https://ghost.slack.com/archives/C02G9E68C/p1670232405014209). So when
running a long import, it is now possible to send emails without having
to wait for the import. Above change makes sure it is not possible to
get around the verification limits.
Refactoring:
- Removed the need to use `updateVerificationTrigger` by making
thresholds getters instead of fixed variables.
- Improved awaiting of members import job in regression test
The MailgunEmailSuppression list was incorrectly adding emails
to the suppression list for permanent failure events which have
an error code outside of the 5xx range.

This ensures that a Member is not considered subscribed to any emails, so that
counts for newsletter recipients are correct. Eventually we will filter members
on their email suppression status but this is not implemented yet.
no issue
- The sleep method has been used in 8 modules reimplementing the same thing over and over again. It's usually a sign of async event processing outside of the request/response loop. It's good to have a single point of implementation for a "hack" like this, so we could track it easier and address the even processing delay in a more optimal way centrally if it ever becomes a bottleneck
refs https://github.com/TryGhost/Team/issues/2339
- Includes a new pattern in the job manager that allows us to properly
await jobs.
- Added new convenience mocking methods to stub settings
- Tests the main flows for bulk sending:
- Sending in multiple batches
- Sending to multiple segments
- Handling a failed batch and retrying that batch
- Fixes bug in batch generation (ordering not working)
In a different PR I'll add more detailed tests.

Saves events in the database and collects error information.
Do note that we can emit the same events multiple times, and as a result
out of order. That means we should correctly handle that a delivered
event might be fired after a permanent failure. So a delivered event is
ignored if the email is already marked as failed. Also delivered_at is
reset to null when we receive a permanent failure.

This moves the processing of the events from the event-processor to a
new email-event-processor in the email-service package.
- The `EmailEventProcessor` only translates events from
providerId/emailId to their known emailId, memberId and recipientId, and
dispatches the corresponding events.
- Since `EmailEventProcessor` runs in a separate worker thread, we can't
listen for the dispatched events on the main thread. To accomplish this
communication, the events dispatched from the `EmailEventProcessor`
class are 'posted' via the postMessage method and redispatched on the
main thread.
- A new `EmailEventStorage` class reacts to the email events and stores
it in the database. This code mostly corresponds to the (now deleted)
subclass of the old `EmailEventProcessor`
- Updating a members last_seen_at timestamp has moved to the
lastSeenAtUpdater.
- Email events no longer store `ObjectID` because these are not
encodable across threads via postMessage
- Includes new E2E tests that test the storage of all supported Mailgun
events. Note that in these tests we run the processing on the main
thread instead of on a separate thread (couldn't do this because
stubbing is not possible across threads)
There are some missing pieces that will get added in later PRs (this PR
focuses on porting the existing functionality):
- Handling temporary failures/bounces
- Capturing the error messages of bounce events
