The Deliverability report, located under the Reports tab, provides a clear, real-time snapshot of your account’s current email and SMS deliverability health. It offers actionable insights and tailored recommendations based on your sender setup, list quality, and engagement metrics.
Email Deliverability
The Deliverability reports tab lists data for both the Email and SMS channels. In the Email channel, you can review several metrics, including sender domain and email address, domain performance, and list hygiene. Each metric is labeled Good, Fair, Poor, or No Status based on your deliverability performance (see the definitions of labels below).
Labels Definition
Sender domains label definition:
Good: you are sending campaigns and automations from verified custom domains;
Fair: you are sending campaigns, automations, or both from our shared domains;
Poor: there are problems with SPF and DKIM record configuration for the custom domains you chose to send from, and action is needed.
Sender email address labels:
Good: you have at least one verified sender email address that contains a custom domain (not Gmail, Yahoo, etc.);
Fair: you have at least one verified sender email address, and that email address contains a public domain (Gmail, Yahoo, etc.);
Poor: there's no verified email address;
No status: there's no email address added.
Email list hygiene labels definition:
Good: when the percentage of high or medium-risk contacts is low;
Fair: when the percentage of medium-risk contacts is high;
Poor: when the percentage of high-risk contacts is high;
No status: when you have fewer than 100 contacts in your audience.
