Email & Notifications
Email clients can't render complex HTML. RendShot renders it as an image. Also for Slack and Feishu bots.
The Problem
Without RendShot
Email clients strip CSS, break layouts, and ignore modern HTML
Slack and Feishu bots can only show images, not rich HTML
Dynamic content (charts, personalized data) impossible in email HTML
Render your content as an image, embed it in the email or bot message. Pixel-perfect in every client, every time.
Unlike embedding raw HTML tables (broken in Outlook) or attaching manual screenshots (not scalable), RendShot generates consistent images from your templates automatically.
How It Works
Three steps. Under a minute.
Design your template
Write HTML + CSS for your image layout. Use Tailwind, Google Fonts, any CSS feature.
Call the API
Send a POST request with your template and dynamic data. Get back a CDN-hosted image URL.
Automate at scale
Hook into your workflow — n8n, Windmill, CMS webhooks, or your own backend. Images on demand.
Integration
One API call. That's it.
curl -X POST https://api.rendshot.ai/v1/image \
-H "Authorization: Bearer rs_live_..." \
-d '{ "template_id": "email-banner",
"variables": { "subject": "Weekly Digest", "stats": "1,247 orders" },
"width": 600, "height": 200 }'FAQ
Common questions
Will the images work in all email clients?
Yes. RendShot outputs standard PNG/JPEG images that display correctly in every email client including Outlook, Gmail, and Apple Mail.
Can I use RendShot with Slack or Feishu bots?
Yes. Generate an image URL via the API, then post it in your bot message. The image is CDN-hosted and loads instantly.
