After you've built a beautiful email in the Letteros editor, a logical question comes up: how do you export it correctly? In this article, we'll explain why you need different formats (HTML, PDF, PNG) and how to prepare them without mistakes.

Why export an email at all

Exporting an email lets you:

  • use it in third-party sending services (HTML),
  • get sign-off on the design from colleagues and clients (PDF),
  • take screenshots for presentations and case studies (PNG).

Exporting to HTML

When you need it

  • For uploading to an ESP (e.g. UniSender, Mailchimp, SendPulse).
  • For handing off to development or a coder.
  • For integrating with internal systems.

How to do it right

  1. In the Letteros editor, click Export → HTML.
  2. Choose:
  • Build full HTML (with inline styles) — if you need ready-to-use code.
  • No external links — if the images are already hosted on a server.3. Check that:
  • all links are active,
  • images are accessible via URL,
  • the code passes validation.

Tip: test the HTML on a test send to make sure the code renders correctly in all email clients.

Exporting to PDF

When you need it

  • For getting design sign-off from management or a client.
  • For archiving or presenting a project.

How to do it right

  1. In the Letteros editor, choose Export → PDF.
  2. Make sure that:
  • all blocks fit on the page,
  • background images display (if needed).3. Check the resulting file for correctness (open it on desktop and on a phone).

Tip: a PDF file is often heavier than HTML — use it only for visual purposes, not for sending campaigns.

Exporting to PNG

When you need it

  • For pasting screenshots into presentations.
  • For publishing email examples on a website or social media.

How to do it right

  1. In the Letteros editor, choose Export → PNG.
  2. Choose:
  • the full email (entire length),
  • a specific block (as needed).3. Download the file and check the quality:
  • whether images have blurred,
  • whether the text is readable.

Tip: PNG is perfect for portfolios and social media, but not for sending via email (HTML is better for that).

Important nuances

  • Always test exported materials, especially HTML.
  • Keep backup copies (e.g. HTML and PNG) to avoid losing anything.
  • If you're sending HTML to third-party services, make sure they support all the CSS styles.

Conclusion

Letteros makes it easy to export emails in the format you need — the key is understanding when and why to use each one.HTML is for sending, PDF is for approvals, PNG is for showcasing.
