What counts as a validation?

Each email address checked through the Mailchk API counts as one validation. Cached results for the same email within 24 hours do not count against your limit.

Can I upgrade or downgrade at any time?

Yes, you can change your Mailchk plan at any time. Upgrades take effect immediately, and downgrades take effect at the start of your next billing cycle.

Is there a free trial for paid plans?

Yes, all paid Mailchk plans come with a 14-day free trial. No credit card required to start.

What happens if I exceed my monthly limit?

You will receive a notification when you reach 80% and 100% of your limit. If you have credit balance, validations will automatically use your credits as overflow. You can also upgrade your plan for a higher monthly limit.

Credits are a pay-as-you-go option. 1 credit = 1 email validation. Buy a credit pack any time — credits are used automatically when your monthly subscription limit is reached. Credits expire 1 year from your most recent purchase, and each new purchase extends the expiry date.

What does the Mailchk Enterprise plan include?

Mailchk Enterprise plans are fully customised to your needs. This includes unlimited validations, advanced validation features (catch-all detection, mailbox existence checking, greylisting detection), dedicated infrastructure, custom SLAs, an account manager, SSO, and invoice-based billing.

Common Questions

We generate a unique test email address for you. You send your email to it from your ESP or marketing tool. Our seed mailboxes across Gmail, Outlook, Yahoo, and other providers receive the email and report exactly where it landed — Primary, Promotions, Spam, or if it was blocked entirely.

We test across all major providers including Gmail (Primary, Promotions, Social, Updates tabs), Microsoft Outlook (Focused, Other, Junk), Yahoo Mail, Apple Mail (iCloud), and AOL. We're continuously adding more providers.

Most tests complete within 2-5 minutes. We wait for emails to arrive at all seed mailboxes, check placement, analyze authentication, and generate your report. You can monitor progress in real-time.

Yes! Inbox placement testing works with any email sending platform — Mailchimp, SendGrid, Amazon SES, Postmark, HubSpot, or any custom SMTP setup. Just send to the test address we generate.

Email validation checks if an email address is real and deliverable. Inbox placement testing checks where YOUR emails land when sent to valid addresses. Validation cleans your list; placement testing ensures your emails reach the inbox.
