Create a free account to receive your initial credits. Once logged in, you can verify emails immediately using single verify or batch upload. Navigate to Settings to generate an API key for programmatic access.

1. 1Sign up at /register and confirm your email
2. 2Log in to access the dashboard
3. 3Choose single verify, batch upload, or use the API

Single verify lets you check one email address at a time in real-time. Enter an email address and get instant results including deliverability status, whether it's a catch-all or disposable address, and the domain's MX records.

1. 1Navigate to Single Verify from the sidebar
2. 2Enter the email address you want to verify
3. 3View the detailed verification result

Upload a CSV file containing your email list for bulk verification. SendClean automatically detects the email column, deduplicates entries, and checks against your suppression list before processing — saving you credits.

1. 1Go to Batches → New Batch
2. 2Upload a CSV file with email addresses
3. 3Select the column containing emails
4. 4Start verification and monitor progress
5. 5Download results when complete

Suppression lists let you maintain a list of email addresses and domains that should be automatically skipped during batch verification. This prevents wasting credits on known-bad addresses and previously unsubscribed contacts.

1. 1Navigate to Suppressions from the sidebar
2. 2Add individual emails or entire domains
3. 3Suppressed entries are automatically excluded from future batches

Generate API keys to integrate SendClean into your own applications. Each key can be used to authenticate requests to our REST API. You can create multiple keys and revoke them at any time.

1. 1Go to API Keys from the sidebar
2. 2Click Generate New Key
3. 3Copy the key — it's only shown once
4. 4Include it in requests as the "x-api-key" header
