Visisto is the website growth system with a built-in block email editor that supports light and dark mode themes, mobile and desktop preview, drag-and-drop blocks, responsive templates, and raw HTML mode — so you can build professional emails without a designer.
Works natively with the tools you already use
Dark mode adoption hit 80%. Mobile email opens passed 68%. But most editors still give you a 2015 drag-and-drop canvas with no dark mode preview and no real mobile testing.
Outdated email editors
Most email editors haven't changed since 2015. Clunky drag-and-drop, no dark mode support, no proper mobile preview. Your emails look different in every client.
68% of emails opened on mobile
No dark mode support
Over 80% of users have dark mode enabled on their devices. If your email editor doesn't let you preview and design for dark mode, your emails look broken for the majority.
80%+ of users use dark mode
Separate tools for building and sending
Design in Canva, export to Mailchimp, test in Litmus, send via Klaviyo. Four tools to send one email. Visisto: build, preview, test, and send — one editor.
4 tools for 1 email
Visisto's block editor lets you design, preview on mobile and desktop, toggle between light and dark themes, and send — all from one screen. No Litmus. No Canva. No export chain.
Drag-and-drop blocks, dark mode preview, mobile toggle, responsive templates, raw HTML, dynamic tokens, and AI generation — all included on every plan.
Text, image, button, divider, spacer, columns, social links, and HTML blocks. Build responsive emails visually.
Design emails for both light and dark mode. Preview and adjust each theme independently. 80%+ of users will see your dark mode version.
Toggle between mobile (375px) and desktop views in real time. See exactly what your subscribers see before hitting send.
Start from pre-built responsive templates or build from scratch. Every template adapts to any screen size automatically.
Switch to raw HTML for full control. Paste custom code, use advanced CSS, or import templates from external tools.
Personalise every email with {{contact.first_name}}, {{shopify.customer.total_spent}}, {{reward.code}} and more. Tokens auto-populate from live data.
Upload, crop, and resize images directly in the editor. Automatic optimisation for fast loading. No separate image hosting needed.
Generate email copy, subject lines, and CTAs with AI. Describe what you want and Visisto writes it. Edit and refine in the block editor.
No code. No middleware. No learning curve. Set up once and let Visisto handle the rest.
Choose from text, image, button, divider, spacer, columns, social links, and HTML blocks. Drag them into your email. Reorder, duplicate, or delete with one click.
Toggle between mobile and desktop views in the editor. See exactly how your email renders on both screen sizes before sending.
Preview your email in both light and dark modes. Adjust colors, backgrounds, and images for each theme. Ensure your email looks perfect everywhere.
Visisto's block editor replaces your email builder, dark mode tester, and mobile preview tool — for a fraction of the cost.
