Verify Emails Directly in the
Platforms You Already Use

Every email you upload passes through 11 verification checks. We start with syntax validation and domain lookup, then verify MX records and perform a direct SMTP handshake with the mail server to confirm the mailbox exists — without sending an actual email. On top of that, we scan for spam traps, disposable addresses, catch-all domains, role-based accounts (like info@ or admin@), and known complainers. We also run bounce prediction and handle greylisted servers with smart retry logic. The result is a confidence score from 0 to 100 and a clear verdict: safe, risky, or invalid.

Our verification engine delivers 99.5% accuracy across all checks. We combine real-time SMTP verification with third-party data cross-referencing to catch edge cases like catch-all domains and greylisted servers that other tools miss. The result is fewer false positives and fewer missed invalid emails. If an email comes back as "unknown" — meaning we genuinely could not determine its status — the credit is automatically returned to your account.

Yes. Every new account gets 200 free credits immediately — no credit card required, no strings attached. You can use these credits to verify emails one at a time or upload a small list. This lets you test the accuracy and speed of our platform before spending a cent. If you need more, our smallest paid plan starts at just $5 for 2,100 credits (including 100 bonus credits).

We offer two ways to buy credits. Pay-As-You-Go (PAYG) lets you buy credits once and use them whenever you want — no subscription, no commitment, and credits never expire. This is ideal for one-time projects, irregular needs, or testing. Monthly Subscriptions give you a recurring allocation of credits each month at a 15–20% discount compared to PAYG. Unused subscription credits roll over to the next month, and you can cancel anytime. Many users combine both — a monthly subscription for regular needs and occasional PAYG top-ups for large unexpected projects.

PAYG credits never expire. Buy them today, use them next month, next quarter, or next year — they will still be in your account. Monthly subscription credits renew each billing cycle, and any unused credits from the previous month roll over automatically. If you cancel your subscription, you keep your remaining credits until the end of your current billing period.

Every purchase — PAYG or subscription — includes bonus credits at no extra cost. These are additional credits automatically added to your account on top of what you paid for. For example, when you buy 10,000 credits for $18, you actually receive 10,500 credits (500 bonus). Bonus percentages range from 3% to 5% depending on the tier. At the highest tier (1,000,000 credits), you get 30,000 bonus credits for free. You do not need to activate or redeem anything — bonuses are applied instantly when you purchase.

Absolutely. You can start with PAYG to test things out, then subscribe to a monthly plan later for the lower per-credit cost. Or you can have an active subscription and still buy PAYG credits on top for overflow projects. If you cancel your subscription, you can continue using any remaining credits and switch to PAYG-only whenever you want. Your existing credits remain available regardless of which billing model you use — PAYG and subscription credits stack together in your account.

We accept all major credit and debit cards through Stripe — Visa, Mastercard, American Express, and Discover. Your card information is never stored on our servers. We also accept cryptocurrency payments including Bitcoin, Ethereum, Litecoin, USDT, USDC, and 100+ other coins. You can save your card for faster future checkouts and to enable the auto-refill feature. Note that crypto payments cannot be used for auto-refill (a saved card is required for automatic purchases).

No. We process your emails in real time and do not permanently store your uploaded lists. Your data is encrypted during processing using 256-bit SSL, and we never share your data with third parties. Once verification is complete, you can download your results and the uploaded data is removed from our systems. Your privacy is not negotiable — we built the platform with data protection as a core principle, not an afterthought.

Speed depends on the size of your list, but most lists are processed significantly faster than competitors. A 10,000-email list typically completes in under 5 minutes. Larger lists of 100,000+ emails may take longer due to the SMTP handshake process with each mail server, but our engine runs multiple checks in parallel to keep things moving. You can track progress in real time from your dashboard, and we will notify you when the task is complete.

Yes. We offer direct integrations with 17+ email marketing and CRM platforms including HubSpot, Mailchimp, SendGrid, ActiveCampaign, Brevo, Klaviyo, ConvertKit, Mailgun, MailerLite, GetResponse, Constant Contact, Drip, and more. You can import contacts directly from these platforms, verify them, and push clean data back — all without exporting CSV files. We also have a REST API with sub-second response times for developers who want to build verification into signup forms, CRM pipelines, or custom workflows.

You have three options. First, you can buy PAYG credits instantly — they are added to your account on top of your subscription balance with no commitment. Second, you can upgrade your monthly subscription to a higher tier for a larger monthly allocation. Third, you can enable auto-refill, which automatically purchases PAYG credits when your balance drops below a threshold you set. This way you never run out unexpectedly during a critical campaign.

Credits are non-refundable once purchased. However, PAYG credits never expire so there is no risk of losing them. If you have a subscription, you can cancel anytime and keep your remaining credits until the end of your billing period. Additionally, credits used on emails that return an "unknown" status — meaning we could not determine validity — are automatically returned to your account. You only pay for definitive results.

Yes. If you need more than 1,000,000 credits per month or have specific requirements, contact us for custom enterprise pricing. Enterprise plans include custom credit volumes, dedicated support, SLA guarantees, volume discounts beyond our standard tiers, and flexible billing arrangements.

It is simple: 1 credit = 1 email verification. Your credits are organized into three buckets — Monthly (from your subscription, expires on renewal), Rollover (unused monthly credits carried forward), and PAYG (one-time purchases, never expire). When you verify emails, the system uses Monthly credits first, then Rollover, then PAYG last. This order protects your permanent PAYG credits by prioritizing expiring credits first. Your total balance and per-bucket breakdown are always visible in your dashboard.

They do not just disappear. Unused monthly credits roll over to your next billing cycle based on how actively you used the service. If you used 75% or more of your plan, you keep 100% of your unused credits. If you used 30–74%, you keep 50%. Even if you used less than 30%, you still keep 25% — we call this the Credit Protection Guarantee. Rollover credits sit in their own bucket and are used after your fresh monthly credits but before your permanent PAYG credits. This system rewards active users while still protecting everyone.

No. Each renewal calculates rollover fresh based on that period's usage only. New rollover replaces old rollover — it does not accumulate indefinitely. For example, if you had 2,000 rollover credits from January and earned 3,000 at the February renewal, you get 3,000 (not 5,000). This prevents credit hoarding and encourages regular usage. Rollover credits are also capped at your plan size — you can never roll over more credits than your plan includes.

If we cannot determine whether an email is valid or invalid — for example, if the mail server did not respond, timed out, or blocked our check — the result is marked as "Unknown" and 1 credit is automatically returned to your account. You are never charged for emails we could not verify. The same applies to unprocessed emails in bulk uploads: if 500 out of 10,000 emails could not be processed, you get 500 credits back instantly. Refunded credits always go to your PAYG bucket so they never expire.

No. When you upload a bulk list, our system detects and removes duplicates before verification begins. You are only charged for unique emails. For example, if you upload 5,000 emails and 200 are duplicates, the system verifies and charges for 4,800 — not 5,000. Duplicate removal is enabled by default and happens automatically. There is nothing you need to do.

Yes. API calls use the exact same credit pool as the dashboard — there are no separate "API credits." Whether you verify emails through the web interface, a bulk upload, or the REST API, credits are deducted from the same balance in the same order (Monthly → Rollover → PAYG). Our API supports single email verification with sub-second response times, bulk verification for large lists, and webhook notifications for async results. Code examples are available in curl, Python, PHP, and JavaScript.

If you are part of a team, all team members share the parent account's credit pool. Every verification performed by any team member deducts from the same balance. Your credit history shows which team member performed each action for full accountability. Only the account owner can purchase credits — team members can see the shared balance but cannot make purchases themselves. This makes it easy to manage verification across your organization without juggling separate accounts.

Choose PAYG if you have one-time projects, unpredictable verification needs, or want to test before committing. PAYG credits never expire so there is zero risk. Choose Monthly if you verify emails regularly, want the lowest per-credit cost (15–20% cheaper than PAYG), and value rollover credits for unused balance. Many users combine both — a monthly subscription for their regular needs and occasional PAYG top-ups for unexpected large projects. PAYG credits stack with your subscription, so both are available in your account at the same time.
