Question 1

How can I check if an email address is valid?

Accepted Answer

Start with instant checks: valid syntax, no domain typos (like gamil.com instead of gmail.com), not a disposable address, and not role-based (like info@). This free verifier runs all of these in your browser. For full mailbox-existence verification, use an SMTP-level verifier like the one built into Vexrim Outreach.

Question 2

Why do emails bounce?

Accepted Answer

The most common causes are typos in the domain, disposable email addresses, mailboxes that no longer exist, and full inboxes. Cleaning typos and disposable addresses before sending removes the majority of hard bounces.

Question 3

What is a good bounce rate for cold email?

Accepted Answer

Keep your bounce rate under 2%. Above 5%, mailbox providers start routing your emails to spam and your sender reputation takes lasting damage. Verifying your list before every campaign is the simplest protection.
