no issue
Mailgun expects `recipient-variables` to be a json object and fails to attempt sending the message in case its undefined, which is the case for test emails as they don't have member `uuid` or `unsubscribe` url. This sets a default empty object for `recipent-variables` in case of no data.
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 :)
no issue
- Tagging needs to be added to be able to group/filter sent messages for various reasons. An example use case is when multiple Ghost instances use the same mailgun account
- Tag value can be provided as a part of config.json file under
`bulkEmail.mailgun.tag` key
