Emails not sending

My app sends and email to me when a new user signs up. It has stopped working. I last deployed in March and sometime after July the emails stopped coming through. Did something change?

I don’t think there has been many changes on the email sending front for Meteor itself. More information might help us help you. First thing I would look at is the transactional email service and make sure your access keys are still valid… Sometimes if there is a breach they will change them and it can be easy to miss those types of emails when they send them. After making sure everything is aligned there, I’d try making a minimal reproduction to see if you can replicate the issue in a new app.
