Challenges of Verifying Emails at Ultrafine.co

Verifying email addresses at ultrafine.co can be a daunting task. The domain is set to catchall, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be effective. Moreover, ultrafine.co may use email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail.

Another challenge is that ultrafine.co may not always return a bounce message even if you send test messages to an invalid email address at that domain. This makes services like Scrubby, which verifies emails by sending test messages, less effective.

Risks of Not Verifying Emails at Ultrafine.co

If you don't verify emails at ultrafine.co, you may end up with a list of outdated email addresses, leading to a high bounce rate. This can damage your sending reputation, resulting in lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.

Moreover, other services may leave most emails at ultrafine.co as risky, making it difficult to decide how to handle them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
