One metric that is often overlooked when it comes to monitoring deliverability is volume. A sender’s volume and their efforts to maintain a consistent sending volume can be just as impactful on deliverability as engagement is.

Meeting the Minimum
The success of a sender’s deliverability is largely the result of the sender’s IP reputation. Part of that reputation is determined based on a sender’s volume practices. If you have a dedicated IP address, in order to build a positive reputation, ISPs will want to see volume being sent off the IP on a regular basis. If you aren’t a high volume sender then building and maintaining a positive sender reputation on a dedicated IP address will become challenging.

Oracle recommends that senders who are sending at least 250k messages per month should be on a dedicated IP. Senders with a smaller volume or infrequent mailings should pursue a shared IP route as the combined efforts with other senders will help meet that minimum.

Keep it Consistent
ISPs determine reputation by 24 hour, 7 day, and 30 day performance trends which makes it critical that sender’s keep a consistent volume from week to week and month to month. If an ISP notices any dramatic deviations from a sender’s volume patterns it will raise a red flag. In the eyes of the ISP, these large dips and spikes mimic the behavior of spammers which will force the ISP to keep a close watch on your program and potentially bulk or block your mailings.

Occasionally marketers will ask if it is okay to send a “one-time” campaign to an audience much larger than what they typically send to. In these scenarios, we advise senders against increasing their typical volume by any more than 25% as any increase larger than this will have a greater chance of creating deliverability issues. If an increase must be made than the increased volume should be spread out over several days to minimize impact.


Summary of Recommendations

  • Keep your volume consistent as well as the frequency at which you email recipients
  • If you are a high volume sender than a dedicated IP is the best route
  • Avoid large increases or decreases in volume to maintain a positive reputation
  • If there is a need to increase volume, spread the additional volume across several days to minimize impact
