Personalized emails outperform generic ones because they feel relevant to each individual reader. Mailzzy makes it simple to insert contact-specific details directly into your email using merge tags — placeholders that are automatically replaced with real data from each contact's record when your campaign is sent.
A merge tag is a short code you place in your email where you want a contact's data to appear. At send time, Mailzzy reads each recipient's contact record and replaces the tag with the corresponding value. If a contact's record has no data for a particular field, the tag is left blank — no error or placeholder text will show.

Note: Send a test email to an address where you know some fields will be missing data — this confirms empty tags display cleanly rather than showing broken code.
