Data quality guarantee
When an email address that Tomba returned hard-bounces, you can claim a credit refund. This page defines which Email Finder and Email Verifier results qualify and how to claim. It doesn't change the Terms of Service, under which Tomba doesn't warrant that any address is deliverable. If you have a signed agreement with Tomba, its terms take precedence over this page.
Email finder
Covers addresses returned by the email finder, domain search, author finder, and LinkedIn finder, through the API or another Tomba tool.
An address qualifies when it meets the conditions for both products and:
- Its
scorewas 60 or higher when Tomba returned it. - You sent to it within 30 days of receiving it from Tomba.
Email verifier
Covers addresses that the email verifier returned with the result deliverable (see Result values), through the API, bulk verification, or the Chrome extension.
An address qualifies when it meets the conditions for both products and you sent to it within 30 days of its verification.
Conditions for both products
- The message hard-bounced because the address doesn't exist: the receiving server rejected it permanently.
- You sent it from a domain authenticated with SPF, DKIM, and DMARC.
- You sent it in compliance with the anti-spam policy.
These are not covered:
- Soft bounces and other temporary failures, such as a full mailbox or an unavailable server.
- Delivery to a spam or junk folder.
- Messages that the recipient's server or filters block or throttle, including rejections based on the message's content or the sender's reputation.
How to claim
- Report each address that hard-bounced. Use
POST /v1/flagwithflag_typeemailandreasonhard_bounce, thetomba flag createcommand, or the report option on the result in the dashboard. Put the bounce message that your mail server received incomment. - Tomba reviews the report and confirms or rejects it. It can ask for the delivery log, the send date, and your domain's SPF, DKIM, and DMARC records to check the conditions above. Follow the report's
statuswithGET /v1/flag,tomba flag list, or the Flags page of the dashboard. - For each confirmed report, Tomba refunds a credit as described in Refunds for incorrect data.
