Verify your Email Lists

Upload your list

To start, drag and drop your file into the dashboard or select it from your computer. You may also copy and paste a comma-separated list of email addresses.

Bulk email verification import options modal.
Details Description
File Processing Our system automatically detects the column containing email addresses. You do not need to remove other columns; we preserve all existing data in your file and will not alter it during the verification process.
Verification Speed and Progress Verification begins immediately after upload. Most lists process quickly, but verification speed can vary depending on the mail servers being checked. In some cases, progress may temporarily slow while certain email addresses take longer to verify, including greylisted or temporarily unavailable mailboxes.
Real-Time Results You do not need to wait for the entire list to finish. You can view verification results in real-time while the verification continues in the background.

Exporting Results

Pre-built export options when exporting email verification results.

Once your list is processed, you can export the data. You are not limited to a single download; you can create as many exports as needed from a single list.

Pre-Built Export Options

We offer three standard presets for quick access

Export Option Results Selection
Deliverable Downloads emails verified as Deliverable
Maximum Reach Includes Deliverable, Risky, and Unknown emails. Use this when your priority is volume over strict safety.
Only Bad Emails Downloads only Undeliverable addresses, useful for suppression lists.
Custom Custom Selection

Custom Exports

custom options when exporting email verification results.

For granular control, you can fully customize your export. You can select any combination of:

  • States
  • Attributes
  • Reasons

You can further filter the export by specific email providers or domains. A summary of your selected filters is displayed at the bottom of the export modal to ensure accuracy before downloading.

List Settings and Management

Data Retention and Deletion: Your data security is paramount. Lists are automatically permanently deleted 30 days after upload. This process is irreversible. You can also manually delete a list at any time before the 30-day limit.

Organization

  • Views: Switch between Card View and List View to suit your workflow.
  • Search: Quickly find specific files using the search bar.
  • Renaming: You can rename lists to keep your dashboard organized.

Recommendation: We advise verifying lists frequently. Email data decays over time, and a list verified months ago may no longer be safe to send to today.
