Mantlz’s email campaign feature lets you send targeted messages to users who submitted specific forms. Build newsletters, announcements, follow-ups, and more with an intuitive campaign builder.
Email campaigns are available on Standard and Pro plans. Free plan users can preview the interface but need to upgrade to send campaigns.

  1. Click “Campaigns” in the main navigation menu
