Why can't I find a specific email address in my user list? Is it blacklisted?

Before concluding that an address is blocked, check how you are looking it up — in Pushwoosh an email address is stored as a device attached to a User ID, and that address is also the device's HWID and push token. User Explorer can find it by the address itself, provided you pick the right search criterion.

How to check properly

1. Open Audience > User Explorer, select the HWID, Email, Phone search criterion and enter the address exactly as it was registered. The match is literal, so if nothing is found try the all-lowercase form as well. You can also search by User ID or by Token.
2. In the profile, open the Devices and platforms tab — registered email addresses appear there alongside push devices.
3. Also confirm the correct project/application is selected: email registrations belong to the project they were created in.
4. Verify your registration flow actually created the address (the /registerEmail call or the import/subscription form succeeded). Registration of an address that is already on the bounce list is rejected with this hwid (email) is blacklisted, so such an address never appears in the base at all.

If the address really is registered but not receiving mail, it may be suppressed after hard bounces or complaints rather than missing from your base. Check the email statistics/error breakdown for that recipient, and see the article on getting notified when an address is blacklisted or bounces. Contact Pushwoosh support with the address and application code if you need the suppression status confirmed.
