ThePurpleBox Transactional Email Sending Policy
At ThePurpleBox, we specialize in sending transactional emails, critical messages such as account notifications, password resets, order confirmations, and other essential communications. To maintain a strong sender reputation and ensure high deliverability, we enforce the following sending policies.
Failure to adhere to these policies may result in rate limitations, temporary suspension, or permanent termination of your account. Below are the key metrics we monitor to ensure compliance and email performance.
Email Sending Thresholds
| Metric | Acceptable Limit | Details |
|---|---|---|
| Bounce Rate | ≤ 5% | The percentage of emails that fail to reach recipients. |
| Spam Complaint Rate | ≤ 0.05% | Transactional emails should have minimal complaints; max 15 per day. |
| Block Rate | ≤ 10% | The proportion of emails blocked before leaving our servers. |
| Spamtrap Hits | 0 | Transactional emails must never hit spam traps. |
| Unjustified Abuse Complaints | 0 | Since transactional emails are expected, unjustified complaints will be reviewed individually. |
ThePurpleBox reserves the right to modify these limits at any time to ensure compliance and maintain service quality.
Key Terms Explained
- Bounces – Emails that fail to be delivered due to incorrect or inactive addresses. Keeping your recipient data up to date minimizes this risk.
- Spam Complaints – Recipients marking your email as spam. Since transactional emails are expected, complaint rates should be exceptionally low.
- Blocks – Emails prevented from leaving ThePurpleBox servers due to repeated delivery failures, spam concerns, or reputation risks.
- Spamtrap Hits – Transactional emails should never reach spam traps, as all recipients should have previously engaged with your service.
- Unjustified Abuse Complaints – If a recipient reports an email as unsolicited despite it being transactional, we will investigate on a case-by-case basis.
By following these guidelines, you ensure reliable email delivery and a strong sender reputation with ThePurpleBox.
