Most sending problems fall under three headings: missing domain verification, volume ramped too fast, or content tripping spam filters.
Checklist
- 1Make sure your domain's SPF, DKIM and DMARC records are verified; status is shown on the Settings → Sending health screen.
- 2Don't skip warm-up; on a new account volume must grow gradually.
- 3Don't send the same text to everyone; keep Echo's personalization on.
- 4Watch reply and complaint rates in Sage's report; if complaints rise the system lowers volume on its own.
Still not fixed?
Email support@e9e.io with the report from the Sending health screen attached; the team reviews your domain setup with you.
