🚀 Pro Tips for Success
- Sender Authentication: Always verify your domain in Settings → Sender Authentication to avoid the "via sendgrid.net" label in inboxes.
- Restricted Keys: Never give an API key more permissions than it needs. If you only need to send mail, only enable "Mail Send".
- Environment Variables: Never hard-code your API key in your source code. Use
.envfiles.
