Campaign hygiene before you hit send

Most deliverability surprises come from small mismatches: a From name that changed mid-week, a tracking domain that looks nothing like the brand, or a landing page that 404s on mobile. A short pre-flight pass catches them.

Identity consistency

• Same display name and reply-to across the sequence.
• SPF/DKIM/DMARC aligned on the sending domain you advertise in the footer.
• No sudden hops to a brand-new subdomain without warm-up.

Link and pixel hygiene

Prefer one stable tracking host. If you need open/click telemetry without cluttering the message, a compact pixel service such as MailPixel keeps the markup tiny while you keep destination URLs under your own domain.

Quick checklist

1. Preview plain-text and HTML on a phone viewport.
2. Click every CTA once from a private window.
3. Confirm the unsubscribe path still works after the last template edit.
4. Archive a copy of the final HTML with the send timestamp.
