Email verification
built into your workflow.

Email verification is the process of checking whether an email address is valid and able to receive messages. It validates the email format, confirms the domain and mail servers are active, checks whether the mailbox exists, and flags higher-risk addresses such as disposable, role-based and catch-all emails before you send.

Unlike standalone email verification tools, One Good Card lets you verify email addresses where you already work. Every verification result stays connected to your CRM, helping you capture leads from digital business cards, maintain accurate contact records and improve email deliverability without switching between multiple platforms.

You should verify email addresses before sending to reduce bounce rates, improve email deliverability and protect your sender reputation. Email verification also keeps your contact lists clean, improves inbox placement and helps more emails reach real recipients.

No. Email verification checks the recipient's mail server without sending an email, so nothing appears in their inbox and the recipient will not know their email address was verified.

Email verification is highly accurate because every email address goes through multiple validation checks, including syntax, domain, MX records, SMTP and mailbox verification. Some domains use catch-all mailboxes that accept every email, making it impossible to confirm a specific inbox. These addresses are marked as Risky rather than Deliverable so you can make an informed decision before sending.

Deliverable means the email address passed verification and is likely able to receive messages. Risky means the address may still receive email but has characteristics such as catch-all, disposable or role-based addresses that reduce certainty. Undeliverable means the address failed verification and should not be used. If the mail server cannot provide a reliable response, the result is marked Unknown and no credit is used.

Email verification uses a simple pay-per-use credit system. Every successful email verification uses one credit, while Unknown results do not consume credits. The same credits can also be used for phone validation and data enrichment. Learn more about credits and pricing.

Yes. Email verification removes invalid and risky email addresses before you send, helping reduce bounce rates, improve sender reputation and increase the likelihood that your emails reach the inbox instead of the spam folder.

Email validation checks whether an email address follows the correct format, while email verification goes further by checking the domain, MX records, mail server and mailbox to determine whether the address can actually receive email.
