Email and sending-domain checks

Open Verification tools. Run an email check and read its result; invalid results are red. For sending-domain verification, follow the displayed DNS record instructions, wait for propagation, then verify. Remove obsolete domain entries using the delete action.

SMTP tester

Select Test Now, enter the connection credentials in the modal, and inspect the result. Testing a server does not create a verified sending account; complete the account verification flow separately.

Email Generator

Choose a count and domain, optionally enable verification, then generate. Export TXT/CSV or move the result to a contact list when appropriate. Generated addresses and syntax/MX checks do not establish mailbox ownership, delivery, or permission. Never use generated addresses for unsolicited campaigns.
