This week we introduced a new feature for our editor in PDF Mail Merger: Placeholder Snapping. This feature makes it easier for you to align placeholders with each other.
Add at least two placeholders to your PDF file. When you select and drag a placeholder, guidelines appear if it intersects a horizontal or vertical position relative to the edges of the other placeholder.
When you see the guidelines, you can drop the placeholder, it will automatically snap to a position that is aligned to the other placeholder.
