Email workflows constantly need images of emails: a thumbnail per template in your campaign tool, a preview for the client approval thread, an archive of every send. Opening templates in a mail client and screenshotting by hand doesn't scale past the first campaign.
Since marketing emails are HTML documents, the html parameter renders them directly — inline styles, web-font fallbacks, and table layouts included.
Render a compiled template
const emailHtml = await renderTemplate("welcome-email", sampleData);const res = await fetch("https://api.screenshotty.link/api/v1/screenshot", {method: "POST",headers: {"X-Api-Key": process.env.SCREENSHOTTY_API_KEY,"Content-Type": "application/json",},body: JSON.stringify({html: emailHtml,viewport_width: 600,full_page: true,format: "image/png",}),});
Everything You Need, Built In
POST the raw template
Send the compiled email HTML (after merge-tag interpolation) and capture the result.
Realistic widths
Capture at 600px for the canonical desktop email view, or mobile widths for responsive QA.
Full-height renders
full_page captures the entire email, however long the template runs.
Batch galleries
Render every template in your library concurrently to build a visual index.
Frequently Asked Questions
Will the image match how Gmail or Outlook renders the email?
The capture shows Chrome's rendering — a faithful view of the HTML itself, ideal for previews, approvals, and archives. Client-specific quirk testing (Outlook's Word engine, Gmail clipping) still needs a dedicated email-testing tool; the two are complementary.
Can I render with sample merge data?
Yes — interpolate your merge tags with sample values before POSTing, so previews show realistic names, prices, and images.
Is there a free tier to try this?
Yes. 100 screenshots per month free, no credit card required. Paid plans start at $9/month for 2,500 screenshots with $0.004 pay-as-you-go overage.
How do teams use this in practice?
Common patterns: a thumbnail per template in the campaign picker, an auto-posted preview image in the approval Slack thread, and a per-send archive image for compliance.
