Deliverability is not a one-time setup — it's an ongoing audit. Before you fix anything, you need to know exactly where you stand. This page is the master checklist every ecommerce brand should run through quarterly, and always before a peak sending period like BFCM.

Why audit first

Most brands only think about deliverability after open rates crash or emails start landing in spam. By then, damage to your sender reputation is already done and can take weeks to repair. A deliverability audit flips this: you catch small problems (a missing DMARC record, a creeping bounce rate) while they're still cheap to fix.

Run this audit quarterly, and always 4-6 weeks before any major sending push (BFCM, a product launch, a big promotional campaign).
