Free email tools for cleaner sending
Check email addresses, DNS records, authentication and deliverability signals before a campaign reaches your sending platform.
Free tools are useful for spot checks. For full lists, check VeriMails pricing and use the same credits for API or CSV verification.
Check the address
Use the email verifier and bounce checker when the question is whether a contact is likely to receive mail.
Check the domain
Use DNS, SPF, DKIM and DMARC tools when a sending domain needs authentication or routing review.
Check the sending risk
Use reputation, blacklist and deliverability tools before larger sends or after bounce, spam or reply patterns change.
Email Verification
Start here when the risk is recipient quality. These tools help with one-off checks, quick triage and deciding when a CSV should go through bulk verification.
Email Authentication
Use these when the sending domain needs clean SPF, DKIM or DMARC records. Authentication does not replace list verification, but broken authentication makes every campaign harder to trust.

Which tool should I start with?
Start with the verifier or bounce checker for recipient quality, DNS tools for authentication setup, and deliverability checks when a domain or campaign starts behaving differently.
Do free tools replace bulk verification?
No. They are best for spot checks and debugging. Use bulk verification when a CSV, CRM export, prospect list, or subscriber file has many addresses.
Do I need list checks and DNS checks?
Yes. List checks reduce invalid recipients. SPF, DKIM, and DMARC help mailbox providers understand whether your domain is authorized to send.
When should I run these checks?
Run them before new domains, large campaigns, DNS changes, list imports, or anytime bounce rates, spam placement, or authentication results change.
