Bulk Email Verification

Bulk verification lets you verify hundreds or thousands of email addresses at once. Upload a CSV file or paste a list directly into the dashboard.

How to Run a Bulk Verification

Option 1: Upload a CSV File

1. Go to Bulk Verify in the sidebar

2. Click Upload File and select a CSV or Excel file

3. EmailKit will detect the columns in your file

4. Select which column contains the email addresses (EmailKit will try to auto-detect this)

5. Click Start Verification

6. Watch the real-time progress bar as emails are processed

Option 2: Paste a List

1. Go to Bulk Verify in the sidebar

2. Click the Paste tab

3. Paste your email addresses — one per line or comma-separated

4. Click Start Verification

Monitoring Progress

Once a bulk job starts, you can track progress in real time:

• A progress bar shows the percentage completed

• You'll see counts of deliverable, undeliverable, risky, and unknown results updating live

• The page uses Server-Sent Events (SSE) for real-time updates — no need to refresh

Downloading Results

When a job completes:

1. Click Download Results to get a CSV file

2. The CSV includes the original email address, verification status, and detailed reason

3. You can also filter results by status before downloading

Viewing Past Jobs

All your bulk verification jobs are saved in the History page:

1. Go to History in the sidebar

2. See a list of all past jobs with their status, email count, and date

3. Click any job to view details or re-download results

File Requirements

• Supported formats: CSV (.csv) and Excel (.xlsx)

• Maximum file size: 25 MB

• One email per row in the selected column

• The first row should contain column headers

Result Storage

Bulk verification results are stored for 14 days after job completion. After that, results are automatically deleted. Make sure to download your results before they expire.

Credit Cost

Each email in a bulk job costs 1 credit. Credits are deducted when the job starts based on the total email count. If some verifications return non-billable results (system errors), those credits are refunded automatically.

Tips

• Remove obvious duplicates from your list before uploading to save credits

• Clean your list of obviously invalid formats (no @ sign, etc.) first

• For very large lists, consider splitting them into multiple jobs

• You can run one bulk job at a time — wait for the current job to finish before starting another
