Understanding Spam and Bounce Rates

Spam Rate

This is the percentage of emails you’ve sent that recipients mark as spam or junk.

  • A high spam rate damages your sender reputation.

  • Poor reputation can result in emails being filtered out or blocked before reaching inboxes.

Pro Tip: Always send to engaged and permission-based audiences to minimize spam complaints.

Bounce Rate

The percentage of emails that fail to reach recipients’ inboxes. Bounces are categorized differently in our system to provide better clarity:


Hard Bounces: Permanent delivery failures.

  • Causes: Invalid email addresses or recipients marking emails as spam.

  • 🛑 These are unrecoverable. You can’t send it to these addresses again.


Note: Our support team is unable to assist with resetting email bounces. If an email soft bounces it will automatically be retried. If it hard bounces, there is no way to change its status. You will not be able to contact that address.

Steps to Monitor and Improve Email Deliverability

  1. Regular Monitoring of Spam Rate:

    • Check the spam rate regularly on the Marketing Email Settings page.

    • Ensure that the rate stays below the 0.1% threshold to avoid deliverability issues.

    • You can also view individual spam and bounce rates for your broadcast emails as well.

  2. Registering Your Domain with Google Postmaster Tools:

    • Since Gmail does not provide spam rate data to email providers, it’s crucial to separately track your performance on Gmail.

    • Register your domain with Google Postmaster Tools by following these steps:

      1. Visit the Google Postmaster Tools site.

      2. Sign in with your administrative Google account.

      3. Add and verify your domain to start monitoring the spam and other important metrics.

  3. Actionable Tips for Reducing Spam Rates:

    • Improve Email Content: Ensure your emails provide value and relevance to your audience. Avoid overly salty language that could trigger spam filters.

    • Optimize Sending Frequency: Sending too many emails can annoy recipients and lead to higher spam rates. Find a balanced frequency that keeps your audience engaged without overwhelming them.

    • Clean Your Email List Regularly: Remove inactive subscribers who do not engage with your emails, as continued sending to these addresses can harm your reputation and increase spam rates.

Important Note:

Uscreen cannot be held responsible for any issues related to the spam rate of your emails. It is your responsibility to take necessary measures to ensure that your email lists are up to date and your recipients have willingly opted to receive emails from you. Please note that our support team cannot assist with improving your spam rates, nor can we help you if your email account gets blocked due to spamming. Therefore, please make sure to comply with the relevant guidelines and regulations to avoid any issues.
