Common challenges
The build cost of an email platform editor.
Shipping a competitive drag-and-drop editor inside your ESP is an 18-month roadmap. Most teams underestimate it on day one.
Without Unlayer
Customers ask for drag-and-drop, you ship a textarea and an HTML import.
Your block library is one engineer-quarter behind your product roadmap.
Every enterprise deal stalls on white-label and theming requirements.
Your AI story is a bolt-on prompt input, not an editor that drafts complete designs.
Multi-tenant theming is hand-rolled and customers see each other’s defaults.
Building an email editor in-house costs years of engineering and ongoing inbox-rendering upkeep.
With Unlayer
Customers design branded emails with drag-and-drop blocks they already expect from modern editors.
A managed template library, brand kits, and reusable block components ship out of the box.
Per-tenant white-label theming closes enterprise deals instead of stalling them.
AI drafts complete multi-block emails, not just subject lines, on brand from the first version.
Multi-tenant theming is first-class so every customer sees their own brand end to end.
A ready-to-embed Email Builder ships in days, not years.
