Our API response time ranges from one to 70 seconds. To ensure speed, we limit the time spent validating each email address. If we encounter a slow mail server or one with a greylisting algorithm, you'll receive an unknown result. You can re-validate these conditions by uploading a file to the bulk email validator.
Typically, 96-98% of domains return results in 1 to 5 seconds. Some domains using Postfix/Dovecot may take up to 20 seconds for real-time validations, and a small fraction of other domains may respond slowly to SMTP inquiries. Major ISPs usually return results in 1 to 3 seconds, covering the majority of email distributions.
