Introduction to Topkey.io

Topkey.io is a financial services company based in San Francisco, California, United States. As a prominent player in the financial industry, Topkey.io relies heavily on email communication to connect with clients, partners, and stakeholders. However, verifying email addresses from this domain can be a daunting task due to its catchall email setup.

Challenges of Verifying Emails at Topkey.io

Verifying email addresses at Topkey.io can be challenging due to several reasons:

• Catchall Emails: Topkey.io uses a catchall email setup, which means that it accepts all emails sent to its domain, regardless of whether the email address exists or not. This makes it difficult for traditional email verification services to determine the validity of an email address.
• Email Security Gateways (ESG): Topkey.io may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. These gateways can make simple SMTP tests fail, making it even harder to verify email addresses.
• Lack of Bounce Messages: Topkey.io may not always return a bounce message even if you send a test message to an invalid email address. This makes it difficult for services like Scrubby to verify email addresses.

Risks of Not Verifying Emails at Topkey.io

Not verifying email addresses at Topkey.io can lead to several risks, including:

• High Bounce Rates: If you don't verify email addresses, you may end up sending emails to invalid addresses, leading to high bounce rates. This can damage your sending reputation, resulting in lower delivery rates, open rates, and click rates.
• Risky Emails: Leaving most emails at Topkey.io as "risky" can lead to uncertainty about how to deal with them. If you keep them, you may risk seeing a high bounce rate, and if you delete them, you may miss potentially valuable valid emails.
