Challenges of Verifying Emails at tre.se

Verifying emails at tre.se can be challenging due to several reasons:

• Email Security Gateways (ESG): There is no information yet about whether tre.se uses email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it can make simple SMTP tests fail, making it difficult to verify emails.
• Catchall Domain: tre.se is a catchall domain, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not work.
• No Bounce Messages: tre.se 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 tre.se

Not verifying emails at tre.se can lead to several risks:

• Risky Emails: Other services may leave most emails at tre.se as risky, so you don't know how to deal with them. If you keep the emails, you may risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
• Outdated List: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate.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.
