Email deliverability is affected by both the deliverability technologies and services that Marketo provides as well as the email marketing practices that you, the sender, follow. Visit our Resource section to learn more about email deliverability best practices.
Deliverability is a complicated concept that is difficult to wrap into a tidy little number or score. However, Marketo monitors email deliverability using a variety of metrics, including:
SenderBase: Part of the Cisco IronPort SenderBase Security Network, SenderBase is a highly relevant measure for B2B email marketers since it focuses heavily on corporations using Cisco security technology. Scores are grouped into three buckets:
- Good = Little or no threat activity
- Neutral = IP address or domain is within acceptable parameters
- Poor = A problematic level of threat activity has been observed from the IP address or domain
Sender Score: Sender Score is an email reputation metric from Return Path that is heavily used in B2C to measure consumer email deliverability. Scores range from 0 to 100.
|Trusted IPs||All IPs|
0 to 100
0 to 100
*Good is the highest score provided by SenderBase.
Scores are an average across all the shared IP addresses used by Marketo customers. Trusted IPs are shared by Marketo customers with a proven track record of trusted email marketing.
Marketo maintains multiple sending IPs accross three data centers; not all IPs are active at any point in time.
