Mailbase Deliverability Controls

Overview

Mailbase deliverability controls span sender-domain verification, suppression enforcement, unsubscribe headers, analytics filtering, bounce and complaint clustering, domain health, webhook debug logs, and safe operational logging.

Compliance Controls

Send-time validation blocks live marketing campaigns that are missing sender, reply-to, compliance footer, unsubscribe URL, or required merge-tag data. One-click unsubscribe headers are added where possible.

Suppression state is enforced across unsubscribed, bounced, complained, and manually suppressed contacts, with admin resubscribe controls and audit logs.

Common Mistakes

Choosing a tool before deciding who owns deliverability.
Treating DNS authentication as a one-time checkbox instead of an operating baseline.
Mixing product-critical transactional email with experimental marketing sends, with no clear boundary.
Trusting headline metrics (like open rate) that privacy proxies now inflate.
