Email Deliverability

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 Scores

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.
