Instantly Email Verification is the platform's email list validation and cleaning tool.
Instantly Email Verification is the platform's email list validation and cleaning tool.
Instantly Email Verification checks an uploaded list before a send: it validates address format, the domain and its mail servers, and the mailbox itself, then flags disposable and catch-all addresses so a sender can decide what to keep. Cleaning runs in bulk rather than one address at a time.
The tool integrates with Instantly campaigns, so a cleaned list loads into outreach without moving between systems. The vendor markets catch-all verification as recovering leads other tools discard, and sells the capability through Instantly Credits with a free starting allowance.
