U31, a company operating in the information technology and services industry, has its domain set up as u31.io. With a catchall email setup, verifying email addresses from this domain can be a challenge. In this blog post, we will discuss the challenges of verifying emails at u31.io, the risks of not verifying them, and how BounceBan can help you overcome these challenges.
Challenges of Verifying Emails at u31.io
Verifying emails at u31.io can be a daunting task due to several reasons. Firstly, there is no information yet about whether it uses email security gateways (ESG) to make simple SMTP test fail, such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If it uses one, it will be a big challenge.
Secondly, since u31.io is set to catchall, simple SMTP tests used by traditional verification services, like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter, millionverifier, cannot verify it. This means that these services will not be able to accurately determine whether an email address is valid or not.
Lastly, u31.io 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 u31.io
Not verifying emails at u31.io can lead to several risks. Other services may leave most emails at u31.io as risky, so that you don't know how to deal with it - if you keep the emails, you may risk seeing a high bounce rate; if you delete all of them, you risk missing the potentially valuable valid emails.
If you don't verify emails, your list will be outdated, and result in a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate. If the bounce rate is too high, your email services providers may restrict your account.
