Email Verification Result Categories

1. Deliverable

The email address is valid and can successfully receive messages. No issues detected with syntax, domain, or mailbox setup.

2. Role-Based

The address is tied to a group or department rather than an individual (for example, info@, support@, sales@). These addresses often have lower engagement and may not be ideal for personalized campaigns.

3. Disposable

The address belongs to a temporary or throwaway email provider. These are often used for short-term sign-ups and may become invalid soon after.

4. Catch-All

The domain is set to accept all incoming emails, even if the specific mailbox doesn’t exist. Verification can’t confirm if the inbox is truly active, so sending may be risky.

5. Mailbox Disabled

The mailbox exists but is currently disabled or inactive. Any emails sent will bounce.

6. Full Inbox

The inbox has reached its storage limit and cannot receive new messages. Delivery will fail until the recipient clears space.

7. Email Reachable

The email server responded, but there’s some uncertainty about whether the message will actually be delivered. It’s considered a risky address.

8. Valid Syntax

The email address format is correct according to standard syntax rules (for example, name@example.com). This does not guarantee deliverability, only that the structure is valid.

9. SMTP Connection

A connection to the mail server was successfully established. This confirms the domain’s mail server is active and responsive.
