# Email verification vs email list hygiene

Verification collects evidence about an address. List hygiene uses collection history, recipient preferences and delivery feedback to maintain a sending list.

| What you want to know | Address verification | Ongoing list hygiene |
| --- | --- | --- |
| Question | What can this check establish about the address? | Does this contact belong in this send? |
| Evidence | Syntax, domain, routing and SMTP where available | Subscription history, exclusions, delivery feedback and engagement |
| An address that stopped working | Can find technical failures; some replies remain inconclusive | Actual bounce records inform the sending rule |
| A contact’s interest | Does not measure interest or permission | Review context and meaningful responses under your own policy |
| Spam traps | Does not identify traps; SMTP acceptance is not a trap check | Review collection and ageing data; no guaranteed trap-free list |
| Timing | At collection and when the evidence needs refreshing | Maintain preferences and exclusions as events arrive |

## What the mailbox check answers

Verification checks syntax, domain and mail routing, and may collect recipient-level SMTP evidence. The result can support a technical decision or leave the mailbox uncertain. It cannot establish that a person wants a campaign, and it does not guarantee inbox placement.

Emvero keeps `status`, `action`, `reason_codes` and `checks` separate so partial evidence remains visible. `unknown` may include valid domain findings; it does not mean that every stage found nothing. The [verification result guide](https://emvero.io/blog/reading-a-verification-result/) shows how to interpret those fields.

## What needs your own sending history

List hygiene includes how an address was collected, what the recipient requested, unsubscribe and complaint exclusions, and actual delivery feedback. Engagement can inform your policy, but it is not a field an external mailbox probe can determine.

An open or click alone does not prove a human response. [Spamhaus explains how protective investigations can produce interactions](https://www.spamhaus.com/resource-center/unravelling-the-myths-of-spamtraps-clicking-links/). Neither a positive check nor an engagement event certifies that an address is free of [spam traps](https://emvero.io/glossary/spam-trap/).

## Use both in the same decision

Keep verification evidence alongside your subscription and delivery records. Apply the most relevant evidence to the next send, holding unresolved cases where your policy requires it. The [list-cleaning guide](https://emvero.io/guides/cleaning-an-email-list/) covers campaign selection; the [CRM email validation guide](https://emvero.io/guides/crm-data-cleaning/) covers storing current and historical results without losing the contact record.
