no issue
- we've had an issue with emails failing due to unexpectedly missing data when inserting email recipient rows
- added a validation check before adding recipient details along with a log so that invalid data can be investigated
no issue
- 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
requires https://github.com/TryGhost/Ghost/pull/12192
- added initial `EmailBatch` and `EmailRecipient` model definitions with defaults and relationships
- added missing `post` relationship function to email model
- fetch member list without bookshelf
- bookshelf can add around 3x overhead when fetching the members list for an email
- we don't need full members at this point, only having the data is fine
- if we need full models later on we can push the model hydration into background jobs where recipient batches are fetched ready for an email to be sent
- bookshelf model instantiation of many models blocks the event loop, using knex directly keeps concurrent requests fast
- adds `getFilteredCollectionQuery` method to base model to facilitate getting a knex query based on our normal model filters along with transaction/forUpdate applied
- store recipient list before sending email
- chunk already-fetched members list into batches and insert records into the `email_recipients` table via knex
- chunked into batches of 1000 to match the number of emails that Mailgun accepts in a single API request but this may not be the absolute fastest batch size for recipient insertion:
| Batch size | Batch time | Total time |
| ---------- | ---------- | ---------- |
| 500 | 20ms | 4142ms |
| 1000 | 50ms | 4651ms |
| 5000 | 170ms | 3540ms |
| 10000 | 370ms | 3684ms |
- create an email_batch record before inserting recipient rows so we can effeciently fetch recipients by batch and store the overall batch status
This reverts commit 80af56b530.
- reverting temporarily so that all associated functionality can be merged in a single release
- creating email batch/recipient records without using them would cause inconsistent data

no issue
- By default for new sites, support address is set same as from address to `noreply` , with full email address using the domain for `@`
- For newsletter emails, the support address was missing the default site domain to be added to address if its `noreply`
- Fix updates the support address to use the same format as from address and add relevant domain for default case
no refs
- The `update` method in members-api package was edited to return Model object instead of JSON directly - TryGhost/Members@a28bcc5
- This unsubscribe handler was returning the raw member object returned from `update` method, which is now a model object and not able to access `member.email`
- Fix updates the unsubscribe request handler to return the member JSON again
no issue
- moves the meat of `pendingEmailHandler()` code into a new function `sendEmailJob()` that is passed over to the new job service
- lets the server keep processing email generation and sending when it receives a shutdown request rather than halting processing mid-send and ending up in a partial state
no-issue
* Added stripeSubscriptions relation to member model
This allows us to fetch the subscriptions for a member via standard
model usage, e.g. `withRelated: ['stripeSubscriptions']` rather than
offloading to loops and `decorateWithSubscriptions` functions, this is
more performant and less non-standard than the existing method.
* Updated serialize methods to match existing format
The current usage of `decorateWithSubscriptions` and the usage of
members throughout the codebase has a subscriptions array on a stripe
object on the member, this ensures that when we serialize members to
JSON that we are using the same format.
There is definitely room to change this in future, but this is an
attempt to create as few breaking changes as possible.
* Installed @tryghost/members-api@0.26.0
This includes the required API changes so that everywhere can use
members-api directly rather than models and/or helper methods
no-issue
- switch from `membersService.api.members.list` to using bookshelf `Member.findPage()` with the `{paid: true}` filter to avoid per-member queries (N+1) to decorate members with subscriptions and a heavy post-fetch filter via `contentGating`
- add concurrency to the Mailgun API requests in `bulk-email` service to reduce overall time submitting API requests
- add debug statements with timing output for easier measurements
- Member limit code was duplicated in 2 places unnecessarily
- Also used member api code that fetched members and subscriptions fully hyrated when we only need a count
- Using a raw query significantly improves performance here
- Represents that logging is shared across all parts of Ghost at present
* moved core/server/lib/common/logging to core/shared/logging
* updated logging path for generic imports
* updated migration and schema imports of logging
* updated tests and index logging import
* 🔥 removed logging from common module
* fixed tests
* moved `server/config` to `shared/config`
* updated config import paths in server to use shared
* updated config import paths in frontend to use shared
* updated config import paths in test to use shared
* updated config import paths in root to use shared
* trigger regression tests
* of course the rebase broke tests
- Use array destructuring
- Use @tryghost/errors
- Part of the big move towards decoupling, this gives visibility on what's being used where
- Biting off manageable chunks / fixing bits of code I'm refactoring for other reasons
no issue
- the `email.{html,plaintext}` fields are only used to display what was sent in the email so it doesn't make sense to store the mailgun-specific content which can be confusing when viewing in the admin area
- store the raw serialized post content with a basic no-data replacement of replacement strings rather than the output of full data fetching and mailgun transformation
no issue
- fixed plaintext templates being word wrapped and breaking across replacement strings
- updated `postEmailSerializer.serialize` to return the email template plus a replacements array that can be used for creating Mailgun-like recipient variable objects or more straight forward replacement
- updated email-preview API to work with the replacements data to show fallback data when previewing
no issue
- with the email replacements feature it's useful to have real member data when sending test emails from the PSM
- if the supplied email address matches a member then that member's data will be used for any replacements
no issue
- in our replacements the member properties are prefixed with `subscriber_` but this wasn't taken into account when requesting data from the member object
no issue
- adjusted mega's post serializer to get full email contents
- fetch `mobiledoc` from the API rather than the pre-rendered `html` and `plaintext`
- re-generate `html` using the mobiledoc renderer with an "email" target so that the email-only card content is included
- re-generate `plaintext` from the newly generated email html
- added replacement handling to mega's `getEmailData` function
- find all of our `%%{replacement "fallback"}%%` instances in the html template and push them into a replacements array with the respective property on the member instance and desired fallback
- transform the replacement for Mailgun compatibility. Mailgun uses `%recipient.variable_name%` for its template variables so we need to replace our custom replacement string with the compatible version. Our replacements system allows for the same replacement (`{subscriber_name}`) to be used multiple times and have different fallbacks, Mailgun doesn't support fallbacks so for each replacement we also need an indexed `variable_name` part so that we can put our fallbacks in the correct place
- perform the same Mailgun template transformation for the plaintext version except we re-use the replacements array to avoid bloating the API request to Mailgun with duplicate template variables for every recipient
- swapped `reduce` for a plain loop for easier readability
no issue
The email data attached to a post when published with send email flag was not filtered on member access, and picked up the whole member list for email data. This resulted in incorrect data stored in emails table even in case of paid-members-only publish, and also incorrect count of "emails sent" being displayed on Admin.
NOTE: The actual emails being sent are still gated by member access, so no emails were sent to anyone without access, this only affected the associated email data and count. Also, the fix here will show correct email sent status for any future post, but will still show incorrect data for any already published posts as the email data in DB is already wrong and will probably need a migration
no issue.
- "[Test]" being appended (at the end of) the test email subject made it hard to scan for test emails. This fixes it by prepending "[Test]" to the subject.
Adds transaction support to `fetchPage` method. This is needed to be able to count members during the post publish transaction.
This is the next iteration over initial quick-fix: 90905b0212
* Added transaction support to pagination plugin
- This support is needed to be able to use `fetchPage` method in transactional context (example usecase was counting members when publishing post for emails)
* Passed transaction related options during email creation
- Without this SQLite would hang in a transaction and eventually timeout
* Updated parameter name for consistency
no issue
- the schedules controller wraps the post creation in a transaction
- we need to pass that transaction through to all other queries, especially on sqlite where a non-transaction query inside a transaction will lock up because there's only 1 connection available
- updates our model method calls to pass through the transaction options
- switches the members service `list()` call to a direct model `findAll()` call to avoid going through our pagination plugin because the raw knex query does not respect the transacting option
no issue
- When whole email batch fails we want to allow retrying sending a batch when post is republished
- Refactored naming for email event handling in mega
no issue
- Increased default mailgun retry limit to 5
- Handling retry logic closer to SDK layer gives less future manual handling
- Allowed failing request to be passed through to the caller
- To be able to handle failed requests more gracefully in the future we need all available error information to be given to the caller
- The previous method with `Promise.all` would have rejected a whole batch without providing details on each specific batch.
- Limited data returned with a failed message to batch values
- Added better error handling on mega layer
- Added new column to store failed batch info
- Added reference to mailgan error docs
- Refactored batch emailer to respond with instances of an object
- It's hard to reason about the response type of bulk mailer when multiple object types can be returned
- This gives more clarity and ability to check with `instanceof` check
no issue
- adds new router to the frontend for handling unsubscribe
- default template lives in `core/server/frontend/views/unsubscribe.hbs`
- `{{error}}` is present and contains the error message when unsubscribe fails
- `{{member}}` is present and contains the member email
- updated unsubscribe url to match the new format
no issue
- The limitation on Mailgun side of API seems to be 1000 emails per message.
- The only place where I could find a hard limit of 1000 emails per
batch was this PHP SDK issue: https://github.com/mailgun/mailgun-php/issues/469
- To store ids of sent messages introduce a mega column on the emails table. They can be synced with stats or other metrics during even pooling in the future
- Removed redundant `join(',')` statement.The SDK accepts an array of emails as well. Less code - better code :)
