Why Small Businesses Need a Good Email Builder

Email marketing has the highest ROI of any marketing channel — averaging $36 for every $1 spent. But for small businesses, the challenge isn't strategy — it's execution. You need emails that:

  • Look professional on every device
  • Don't require coding skills to create
  • Work in Gmail, Outlook, and mobile
  • Can be exported to any email platform
  • Don't cost money to build

What You Can Build

MailViewr's email builder includes drag-and-drop components for every common email type:

  • Newsletter emails — Multi-column layouts with images and text
  • Promotional emails — Hero banners, CTA buttons, product cards
  • Announcement emails — Simple text with branding
  • Welcome emails — Onboarding sequences for new customers
  • Transactional emails — Order confirmations, receipts

How It Works

  1. Drag and drop — Add headers, images, text blocks, buttons, columns, and dividers
  2. Customize — Change colors, fonts, spacing, and alignment without code
  3. Preview — See how it looks in Gmail, Outlook, and mobile instantly with the email preview tool
  4. Check compatibility — Get a compatibility score and fix any issues
  5. Export — Download or copy the email-safe HTML code
  6. Send test — Send the email to your inbox to verify real rendering
