Email Deliverability and Domain Authentication

Deliverability boundary

SophMate alerts, support handoffs, contact confirmations, and campaign-adjacent workflows depend on mail delivery that operators can trust. A successful local send test is not enough when sender identity, spam placement, bounce handling, or reply routing is unclear.

Domain checks

Confirm SPF, DKIM, DMARC alignment, sender domain ownership, reply-to routing, bounce monitoring, and mail-provider logs before production notifications matter. Pair this with Mail and Notification Settings, Watchers and Alerts, and Diagnostics and Support.

Operational response

When mail delivery fails, preserve provider logs, timestamps, recipients, and affected workflows before changing multiple settings. Review whether missed messages should trigger Incident Response Runbook.

Owner and cadence

• Primary owner: site administrator with provider, billing, and security responsibility.
• Review cadence: after provider, mailbox, role, budget, security, WooCommerce, or integration changes.
• Escalate when sender authentication, bounce handling, reply routing, or mail-provider logs cannot prove reliable delivery.

Production checklist

• Verify SPF, DKIM, DMARC alignment, sender domain ownership, reply-to routing, bounce monitoring, and mail-provider logs.
• Test operational messages beyond a single local send by checking inbox placement, bounces, replies, and affected workflow alerts.
• Document who owns provider credentials, budget limits, role access, notification routing, and ongoing review.
• Keep configuration changes behind administrator access and review them after plugin updates, staff changes, or incidents.

Acceptance checks

• Critical SophMate notifications can be traced through the mail provider and reach monitored recipients.
• Missed or bounced messages have an owner, evidence trail, and escalation path.
• A second administrator can explain why each high-risk setting is enabled and who may change it.
• No production credential, support mailbox, or notification path depends on an unmanaged personal account.

Common mistakes

• Trusting a single successful test email without checking domain authentication, bounces, spam placement, and reply routing.
• Using personal provider keys, personal mailboxes, or broad administrator access because it is faster during setup.
• Changing budgets, roles, notifications, or integrations without recording the owner and review reason.
