I have setup a domain and then setup sendgrid with no problems. I have then changed my domain name through google. This has changed over to the new domain however; the ‘emails sent from your app come from’ is still saying the old domain. I can’t figure out how to change this.
Could you post a screenshot of your Settings > Domain / Email tab of your editor with both the “Domain Setting” and “Email Settings” sections visible? (Feel free to send in a PM if you prefer not to share publicly).
To confirm, have you pushed from development to live recently?
To troubleshoot, try removing your associated SendGrid details on the Settings > Domain and Email tab and then re-applying them.
