FAQ's

Frequently Asked Questions

VerifySwift uses multiple verification layers, including MX record checks, domain validation, and real-time SMTP pinging. We also detect disposable and temporary addresses to keep your list pristine.

Unlike other solutions, VerifySwift can verify the most difficult email service providers - including Yahoo/AOL, Outlook, Mimecast, etc. You can test emails from these providers to gauge others' accuracy. If you need sample email addresses to do so, just reach out to our support.

VerifySwift lets you configure complex custom rules. For example, you can tag emails containing "+" as invalid to block otherwise valid Gmail addresses of temporary email providers. VerifySwift even lets you configure nested verification rules for the most complex tasks.

VerifySwift also never sends actual emails to detect bounces. We use proprietary methods to check validity without doing so. This way, when users use email addresses unique to your service, i.e. john.doe+{yourdomain.com}@gmail.com", they don't receive gibberish emails that are clearly originating from you.

We also maintain the largest and most up-to-date database of spam trap and disposable email providers.

Just reach out to our support. We would be happy to integrate VerifySwift into your existing platform, CRM, or anywhere else.
