- store raw content in email record
- keep any replacement strings in the html/plaintext content so that it can be used when sending email rather than needing to re-serialize the post content which may have changed
- split post email serializer into separate serialization and replacement parsing functions
- serialization now returns any email content that is derived from the post content (subject/html/plaintext) rather than post content plus replacements
- `parseReplacements` has been split out so that it can be run against email content rather than a post, this allows mega and the email preview service to work with the stored email content
- move mailgun-specific functionality into the mailgun provider
- previously mailgun-specific behaviour was spread across the post email serializer, mega, and bulk-email service
- the per-batch `send` functionality was moved from the `bulk-email` service to the mailgun provider and updated to take email content, recipient info, and replacement info so that all mailgun-specific headers and replacement formatting can be handled in one place
- exposes the `BATCH_SIZE` constant because batch sizes are limited to what the provider allows
- `bulk-email` service split into three methods
- `send` responsible for taking email content and recipients, parsing replacement info from the email content and using that to collate a recipient data object, and finally coordinating the send via the mailgun provider. Usable directly for use-cases such as test emails
- `processEmail` takes an email ID, loads it and coordinates sending related batches concurrently
- `processEmailBatch` takes an email_batch ID, loads it along with associated email_recipient records and passes the data through to the `send` function, updating the batch status as it's processed
- `processEmail` and `processEmailBatch` take IDs rather than objects ready for future use by job-queues, it's best to keep job parameters as minimal as possible
- refactored `mega` service
- modified `getEmailData` to collate email content (from/reply-to/subject/html/plaintext) rather than being responsible for dealing with replacements and mailgun-specific replacement formats
- used for generating email content before storing in the email table, and when sending test emails
- from/reply-to calculation moved out of the post-email-serializer into mega and extracted into separate functions used by `getEmailData`
- `sendTestEmail` updated to generate `EmailRecipient`-like objects for each email address so that appropriate data can be supplied to the updated `bulk-email.send` method
- `sendEmailJob` updated to create `email_batches` and associated `email_recipients` records then hand over processing to the `bulk-email` service
- member row fetching extracted into a separate function and used by `createEmailBatches`
- moved updating of email status from `mega` to the `bulk-email` service, keeps concept of Successful/FailedBatch internal to the `bulk-email` service
