Why Iterable users choose Letterhead

Creation and workflow in one place: Letterhead gives editors and producers a fast way to build newsletters with templates, approvals, and consistent layouts. Iterable handles delivery and subscriber data so teams can plug into their existing infrastructure.
Flexible sending with stronger editorial control: Teams create the entire edition in Letterhead and push it into Iterable for segmentation, personalization, and reporting. This keeps editing and production separate from delivery logic, which prevents versioning issues and saves hours each week.
Revenue workflows that slot into Iterable’s sending system: Letterhead manages sponsorship placement, partner content, inventory, and layout. Iterable sends the final edition without requiring teams to rebuild or copy anything.
