Email verification comparisons

# Compare email verification methods and results

Choose the comparison that matches your decision: which checks to run, when to run them or how to interpret the response. Each page explains the evidence, limitations and practical tradeoffs of the two approaches.

## Choose a comparison

### Syntax validation vs SMTP verification

Format rules catch malformed addresses; an SMTP probe can add recipient evidence. Neither guarantees message delivery.

### Real-time vs list verification

Check one address while someone waits or work through a stored list. Compare timing, pending responses and the workflow your system manages.

### Email verification vs list hygiene

Technical address evidence and ongoing subscription, suppression and engagement records answer different sending questions.

### Domain check vs full verification

Domain depth checks syntax and routing without SMTP. Full verification may add recipient evidence when the destination permits it.

### Unknown vs undeliverable

Separate inconclusive evidence from a permanent technical failure, then choose whether to retry, confirm or reject.

### Confidence score vs check evidence

A confidence score is not a delivery probability. Check stages, reason codes and the recommended action explain the result.

### Disposable-domain lists vs API checks

A reference list identifies known disposable domains. Current DNS and SMTP evidence answer different questions about an address.
