Best Practices Regarding Request Per Minute (RPM)

In email campaigns, RPM (requests per minute) refers to the number of emails sent per minute. Effectively managing your RPM is crucial for maintaining a positive sender reputation and ensuring high email deliverability. This guide outlines best practices to help you optimize your RPM for successful email campaigns.

  • Use an RPM of 1000: During the warm-up phase, make sure the RPM is 1000 for the first 10 days.  The warm-phase mentioned includes RPM recommendations also.
  • Increase RPM: After ramping up, increase your RPM gradually each week. This steady growth signals to ISPs that your sending volume is organic and consistent, which helps to maintain strong deliverability.
  • Use low RPM: If you are sending emails after a pause of more than 10 days, use low RPM and spread the email volume over 3 hours. This re-establishes your sending reputation with ISPs after a period of inactivity, reducing the risk of emails being deferred or blocked.
  • Configure RPM: Ensure that you configure RPM so that you can send the entire email volume within one hour or less.
    • RPM * 60 = Volume delivered in an hour.
  • Monitor and slowly increase your RPM: If you're sending emails at a low RPM and spaced out over time, gradually increase the RPM. Allow one week for each adjustment to take effect. Keep a close watch to ensure there are no deferrals.
