Yes—if you send email marketing or transactional email, you should monitor inbox placement.
Why it matters:
- Delivery isn’t enough. A message can be “delivered” but still land in spam, promotions, or be filtered.
- It affects revenue and engagement. Inbox placement impacts opens, clicks, and conversions.
- It helps catch reputation problems early. Issues like spam complaints, authentication failures, or poor list hygiene can quietly hurt performance.
- Provider behavior changes. Gmail, Outlook, Yahoo, and others regularly update filtering rules.
What to monitor:
- Inbox vs spam placement across major mailbox providers
- Authentication: SPF, DKIM, DMARC
- Bounce rates, complaint rates, unsubscribe rates
- Engagement trends: opens, clicks, replies, conversions
- Sending reputation and any sender score signals
- Seed tests / inbox placement tests for visibility into foldering
If you send email at any meaningful volume, monitoring inbox placement is a good practice—not just a nice-to-have.
If you want, I can also tell you how to monitor it or which tools to use.
