As a fallback for users without desktop notifications turned-on etc. we'd like users who miss key messages (individual mentions currently, but group mentions and potentially other ) to hear about them via a communication channels they're very familiar with and unlikely to ignore - email.
This lambda runs every 5 minutes and does the following...
- queries the DB for
- items with individual mentions which have remained unread for more than an hour (by those mentioned) and haven't had
isEmailEvaluatedset to true. - items where
Central Productionis group mentioned and haven't hadisEmailEvaluatedset to true.
- items with individual mentions which have remained unread for more than an hour (by those mentioned) and haven't had
- collates all items into per-user data structure, and then per-pinboard within that
- looks-up the working titles and headlines from workflow (by invoking
workflow-bridge-lambda) - loops through the users, sending them an email (using AWS Simple Email Service (SES)) from the relevant pinboard domain -
[email protected]or[email protected]- These domains are registered as 'SES verified identities' and DNS validated automatically via CDK code 🎉 .
- The email is rendered using
preact(like the client) but usingstyleattribute rather than emotion, for best compatibility with email clients.
- sets
isEmailEvaluatedto true for the items it has emailed about
Note that CODE emails are flagged as External - because code.dev-gutools.co.uk is not an alias in gSuite, but gutools.co.uk is.
