Sendgrid does not provide Email Notifications* for Bronze plan. But in MassMailer app, we have customized the Statistics for Campaign and Mass Email Wizard in such a way that:
[* - Email notification notifies the user about the status of the sent emails. For e.g., Delivered, Bounce, Open, Clicks etc.]
A. User will see a section naming MassMailer Email Statistics under Campaign detail page which includes:
A scheduler runs on daily basis which will check a check box naming Invalid Email on Lead and Contact Objects for Invalid, Bounce and Spam emails and for Unsubscribe emails - Email Opt Out and Invalid Email check boxes will be checked for Lead and Contact Objects.
