My app sends different transactional emails (using Sendgrid) for different events:
User A only wants to know when people follow her. User B only wants to know when people like or share his picture. User C wants all the emails.
Is there any way to manage the subscriptions to these different transactional emails using Sendgrid? Is there some kind of 'category' email subscription functionality?
If not I'm guessing I'll have to store this locally in the database.
