CampaignKit FAQs

• How do you protect my data?

  We keep submitted email addresses during the lifetime of the validation. No email addresses are stored on CampaignKit's servers nor do we forward the email addresses to any 3rd party service. All communication between you and the CampaignKit servers is encrypted.
• Do you send emails during the validation?

  No. No emails are ever send to the recipient's mailbox.
• How do you perform mailbox deliverability validation?

  The validator tries to connect to the recipient's mail server, issues a MAIL command (using an email address from the validator not associated with you) followed by an RCPT command with the email address. Email servers respond with some defined response codes and additional information. This is used to detect if the mailbox is available. Instead of continuing the session, the connection will be closed (no email will be sent).
• Does this work for ESPs like gmail?

  Yes. Mailbox deliverability validation works for ESPs like gmail.com, icloud.com, yahoo.com. Some providers may impose penalties for too many connection attempts, temporarily rejecting new connections, which requires the validator to slow down.
• Do I need to buy credits?

  Yes. You buy credits depending on your needs. A credit is only used for successfully validated emails. You don't pay for syntax failures. You get 25 email validations for free upon signup.
