Direct answer
Yes. Verification judges the email address, not whether a contact has a first name. Handle missing names as a separate personalisation rule.
More questions and answers
How do I remove one-letter first names without deleting valid emails?
Flag one-letter names for review or omit personalisation while retaining the address record. A one-character first name does not prove the email is invalid.
Can an email cleaner guess first names from email addresses?
Sometimes a first.last pattern provides a plausible guess, but it can be wrong. Mark inferred names and never present them as verified identity.
How do I clean emails but keep their country field?
Retain a stable contact ID and merge the verification results back into the original full table. Email validity does not determine a contact's country.
Why did my email cleaner put the wrong name next to an address?
This usually happens when result rows are merged by position after sorting. Match by original row ID or a unique contact key and review collisions.
How do I capitalise names without changing email addresses?
Transform the name fields separately and avoid changing mixed-case surnames automatically. Email addresses can be normalised independently for duplicate matching.
