Verify a Single Email Address

Before following up with a new lead, it helps to know their email address actually works. One Good Card's built-in Email Verification tool checks this in seconds, right from the contact record, so you're not sending into a dead inbox.

How to Verify a Single Email Address

1. Log in to your One Good Card dashboard.
2. Go to Contact Manager.
3. Open the contact whose email you want to verify.
4. Click Edit
5. Click Verify Email next to their email address.
6. Wait a few seconds for the check to complete.
7. View the result directly on the contact record.

Understanding the Result

Each verification returns one of four outcomes:

• Deliverable: the email passed all checks and is likely able to receive messages
• Risky: the address may still receive email but has traits like catch-all, disposable, or role-based that reduce certainty
• Undeliverable: the address failed verification and should not be used
• Unknown: the mail server did not give a reliable response, no credit is used in this case

Alongside the result, you'll also see a deliverability score from 0 to 100 and a breakdown of individual checks: valid format, mail server found, mailbox exists, and business domain.

✨ Pro Tips:

• Verify a lead's email as soon as it comes in, before you spend time drafting a follow-up.
• If a result comes back Risky, don't discard the contact automatically. Cross-check the address manually or reach out through another channel first.
• Re-verify older contacts periodically. Email addresses can become inactive over time even if they were valid when first added.
