Topcon.de is a German company that specializes in precision instruments, optical instruments, and electronic instruments. As a leading brand in the industry, they have a significant online presence, and verifying emails at their domain can be a challenging task.

Challenges of Verifying Emails at Topcon.de

Verifying emails at topcon.de can be tricky due to several reasons. Firstly, there is no information yet about whether they use email security gateways (ESG) to block simple SMTP tests, which can make traditional verification services fail. Additionally, topcon.de may be 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 them. Furthermore, topcon.de may not always return a bounce message even if you send test messages to an invalid email address at that domain, making services like Scrubby not work.

Risks of Not Verifying Emails at Topcon.de

Not verifying emails at topcon.de can lead to several risks. Other services may leave most emails at topcon.de as risky, leaving you unsure of how to deal with them. If you keep the emails, you may risk seeing a high bounce rate, and if you delete all of them, you risk missing potentially valuable valid emails. Moreover, if you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and subsequently, lowering your delivery rate, open rate, and click rate. If the bounce rate is too high, your email services providers may restrict your account.
