Each email address checked counts as one verification — whether it's from a CSV upload or a single check in the tool. Duplicate emails in a batch only count once.
Do unused verifications roll over? ▼
No — verifications reset at the start of each billing cycle. If you consistently need more, consider upgrading your plan.
How accurate is the verification? ▼
TrueSendy uses multi-layer verification: syntax check → DNS/MX lookup → DNS-over-HTTPS fallback → SMTP handshake probe. Accuracy is 95–98% on most providers. Some enterprise servers (Google Workspace, Microsoft 365) block SMTP probes, so those return "probable valid" status.
Can I upgrade or cancel anytime? ▼
Yes — upgrade, downgrade, or cancel from your account settings at any time. No long-term commitments. Cancellations take effect at the end of your current billing period.
Is there a free trial? ▼
Yes — all new accounts start with 50 free verifications with no credit card required. This gives you a chance to test the accuracy before committing to a paid plan.
