Enhanced Validation Credits

Enhanced validation credits are one of the features that set Truelist apart from other email validation services. Rather than relying solely on SMTP-based validation, enhanced validation uses a host of other heuristics to gain a definitive signal on the validity of an email address. While enhanced credits work for most difficult-to-validate email addresses, they are not guaranteed to work for all email addresses.

Supported Providers

We’ve fine-tuned enhanced validation to work particularly well with the following providers:

  • Google Workspace — Business emails hosted on Google Workspace
  • Microsoft business emails — Outlook, Office 365, and other Microsoft-hosted domains
  • Yahoo, AOL, and Hotmail — Consumer email addresses on these platforms

How Enhanced Credits Work

Enhanced validation credits are available as an add-on to the regular email validation service. Here’s how they work:

  1. Purchase credits — You can purchase enhanced credits on the billing page.
  2. Choose when to use them — When verifying a single email or verifying a list, you can choose to use enhanced validation. It’s not applied automatically — you decide when to use your enhanced credits.

Pricing

You are charged for enhanced validation credits on a per-email basis. The cost is higher than regular validation credits due to the additional resources and processing time required. You can view your enhanced credit usage and costs in the dashboard.

When you use enhanced validation, you are only charged an enhanced credit — a regular credit is not also deducted (unless you are on an unlimited plan, in which case regular credits are not applicable).

Performance Considerations

Enhanced validation can take significantly longer than regular validation. We recommend using it selectively for email addresses that are difficult to validate with regular credits, rather than applying it across your entire list.

If you need the highest accuracy on a specific segment of your list — such as business emails from Google Workspace or Microsoft domains — enhanced validation is a great fit. For general-purpose validation, the standard Accurate strategy is sufficient for most use cases.
