Why Email Verification Matters
Sending to unverified addresses is the fastest way to wreck your deliverability. Every hard bounce signals to inbox providers that you are not a careful sender, which pushes even your good emails to spam. Verifying before you send keeps your bounce rate low, your domain reputation healthy, and your messages in the primary inbox.
How to Verify an Email Before You Send
1. Check the syntax and domain are valid
2. Confirm the mail server accepts the address
3. Flag catch-all domains that accept anything
4. Remove role addresses like info@ that rarely reach a person
5. Re-verify periodically, since people change roles
Rather than building this pipeline yourself, start with a source that verifies at capture. JustRaised contacts are verified, so you can focus on the message instead of list hygiene.
