There is an email dashboard sent to support@healthily.com.au daily which is from metabase@healthily.com.au and contains a bunch of tables.
At the moment, the subject line for this email is SMS Whispir Twilio. Because the subject lines are all the same, google is threading them and when there are more than a dozen or so, all the tables in the email begin to fall apart (presume the gmail has trouble threading that much data).
Can you add the current date into the subject line for these emails? (which will prevent them threading)
Screenshots of the issue attached.
