Inbox providers watch how often your email bounces or is reported as spam. Yourdiai tracks the same levels Amazon SES uses to review senders.
- Bounce rate: aim below 2%. Above 5% is critical.
- Complaint rate: aim below 0.08%. Above 0.1% is critical.
How to stay healthy
- Only email people who opted in.
- Remove old, unengaged addresses before you import.
- Use a sender name and subject line your audience recognises.
