Free Close Email List Verifier

Close is a sales CRM built specifically for inside sales teams, featuring built-in calling, email sequences, and pipeline management in a single workspace.

Why verify your Close email list

Close is designed for high-volume outbound sales, where reps send hundreds of emails per day through built-in sequences. Invalid addresses in your Close account generate bounces that damage your sending domain and waste valuable selling time. Verification ensures every sequence reaches a real inbox.

Maximize Sequence Performance
Close sequences are built for volume. Verified contacts mean every automated email reaches a real person instead of bouncing.

Protect Your Sending Domain
High-volume outbound from Close amplifies the damage of bad addresses. Verification keeps your bounce rate low and your domain safe.

Reliable Sales Metrics
Close tracks email opens, clicks, and replies. Invalid contacts distort these metrics and make it harder to optimize your outreach.

Save on Per-Seat Costs
Close is priced per seat with sending limits. Don't waste your team's allocated sends on emails that will never be delivered.

Frequently asked questions

Can't find the answer you're looking for? Reach out to our customer support team.

Does Close verify emails?
Close does not include email verification. It tracks email delivery status after sending but does not validate addresses before outreach. Truelist lets you verify contacts before you send a single email.
How do I export leads from Close?
Use Smart Views in Close to filter your leads, then click the Export button to download them as a CSV. Include email addresses and any other fields you want to preserve.
Why is verification important for outbound sales teams?
Inside sales teams using Close send high volumes of email. Even a small percentage of invalid addresses can generate enough bounces to trigger spam filters and hurt deliverability for your entire team.
How often should I verify contacts in Close?
Verify before loading new lead lists and at least quarterly for existing contacts. Outbound sales data decays quickly since prospects change roles and companies frequently.
