Subject: Sending emails with SPF but without DKIM?

1. Email providers (Gmail, Yahoo, Outlook) require proper authentication (SPF + DKIM) to trust and deliver emails reliably.
2. With QuestionPro’s email servers, DKIM is mandatory to send emails from a custom domain. If DKIM is not configured, the domain remains unverified and emails cannot be sent using that domain.
3. Without DKIM, even if sending were allowed, deliverability would be significantly lower — with a higher chance of emails landing in spam or being rejected due to lack of authentication.

4. Recommended approach:
Re-check with your domain host — most providers support DKIM (often under “Advanced DNS” settings)

5. Alternative:

Use a custom SMTP setup — emails would be sent via the custom SMTP servers, and QuestionPro does not enforce domain authentication in this case.

Summary:

DKIM is mandatory for sending emails via QuestionPro" email servers.
