Verifying email addresses is an essential step in maintaining a healthy email list and preventing bounces. However, verifying emails from certain domains, such as vip.sina.com, can be a challenge. In this blog post, we'll explore the difficulties of verifying emails from vip.sina.com and how BounceBan can help you overcome these obstacles.
About vip.sina.com
vip.sina.com is a domain owned by Sina Corporation, a Chinese technology company that operates several popular online services, including Sina Weibo, a microblogging platform, and Sina News, a news portal. As a prominent online service provider, vip.sina.com has a large user base, which makes it an attractive target for spammers and phishers.
Challenges of Verifying Emails from vip.sina.com
Verifying emails from vip.sina.com can be tricky due to several reasons:
- Email Security Gateways (ESG): vip.sina.com may use email security gateways, such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail.
- Catchall Emails: vip.sina.com 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: vip.sina.com 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 from vip.sina.com
Not verifying emails from vip.sina.com can lead to several risks:
- High Bounce Rates: If you don't verify emails, your list will be outdated, and you may see a high bounce rate, damaging your sending reputation and resulting in lower delivery rates, open rates, and click rates.
- Restricted Account: If the bounce rate is too high, your email service providers may restrict your account.
- Missed Opportunities: By deleting all unverified emails, you risk missing potentially valuable valid emails.
