Challenges of Verifying Emails at vdv.uni-frankfurt.de
Verifying emails from vdv.uni-frankfurt.de can be a daunting task due to several reasons:
- Email Security Gateways (ESGs): There is a possibility that vdv.uni-frankfurt.de uses ESGs 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 difficult for traditional verification services to verify emails.
- Catchall Emails: vdv.uni-frankfurt.de 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 cannot verify these emails.
- No Bounce Messages: vdv.uni-frankfurt.de may not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby not work.
Risks of Not Verifying Emails at vdv.uni-frankfurt.de
Failing to verify emails from vdv.uni-frankfurt.de can lead to several risks, including:
- High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and lowering your delivery rate, open rate, and click rate.
- Risky Emails: Other services may leave most emails at vdv.uni-frankfurt.de as risky, so you don't know how to deal with them. If you keep the emails, you may risk seeing a high bounce; if you delete all of them, you risk missing potentially valuable valid emails.
