About this template
Trial Ending Email — Free SaaS Trial Expiration & Upgrade Template
Trial Ending Email is a free, responsive HTML template for the most important email in a SaaS trial: the reminder that it's about to end. Sent a few days before expiry, it turns engaged trial users into paying customers by showing what they've already built and making the upgrade one click away.
What's in the email
A "Your trial ends in 3 days" pill, a headline about keeping everything they've built, and a short intro with the end date. Three usage stats show the value they've already got (projects created, teammates invited, hours saved), followed by a plan card with the plan name, price, billing period and four key features with check marks. An "Upgrade" button, a "Compare all plans" link and a reassuring note about what happens to their data finish the email, signed by a real person.
Built to convert, coded for inboxes
Personal usage numbers are more persuasive than a generic feature list, and a reassuring "your data is safe" note lowers the pressure that makes people walk away. The stats, plan card and button are built with tables and inline styles, so they hold their shape in Outlook on Windows, Gmail and Apple Mail, and the button goes full width on phones. A dark palette and plain-text version are included.
Part of your lifecycle emails
Fill the stats from your product data with merge tags in Customer.io, Intercom, HubSpot, Loops or your own code. It follows the Welcome Email in an onboarding sequence; after upgrade, send a Payment Receipt.
Extend with AI
Take This Email Further With AI
Give this prompt to an AI assistant to write your own version of the Trial Ending Email email: draft ten subject lines and preheaders, adapt the copy for a customer segment, translate it, convert it to MJML or React Email, or write the plain-text version. Then paste the result back into the editor above to check it in desktop, mobile and dark mode.
Prompt to recreate it
Copy this into your AI assistant of choice to build the effect from scratch, or as a jumping-off point for your own variant:
Create a responsive HTML email: “Trial Ending Email”, an onboarding email.
Purpose: A SaaS trial-expiry reminder that converts: a "your trial ends in 3 days" label, a headline about keeping what they built, three usage stats from the trial, a plan card with price, period and four key features, an upgrade button, a compare-plans link and a reassuring note about what happens to their data.
Inbox text:
- Subject line: “Your Acme trial ends in 3 days”
- Preheader (hidden preview text): “Keep your projects, your team and everything you’ve set up. Upgrade in one click.”
Content, top to bottom:
- Message & button
- Usage stats
- Plan card
Headline: “Keep everything you’ve built, {{first_name}}”. Main button: “Upgrade to Pro”.
One primary action only, with short body text, so a new user knows exactly what to do next.
Build it like a professional email developer:
- Table-based layout, 600px wide on desktop and fluid on mobile (width 100%, max-width 600px).
- Inline CSS on every element, with one small style block only for media queries and dark mode (prefers-color-scheme).
- A bulletproof, Outlook-safe call-to-action button (padded table cell with a VML fallback), never an image.
- Colours: brand and button #0f766e, button text #ffffff, page background #eef0f7. Web-safe font stack with a fallback after the brand font.
- Every image has alt text and explicit width and height. Use PNG icons, never SVG, because Gmail and Outlook drop them.
- Hidden preheader text, a plain-text version, and a legal footer with the postal address, the reason the person is receiving it and a working unsubscribe link.
Finish with a short checklist of what to test in Gmail, Outlook for Windows, Apple Mail, mobile and dark mode.Want to tighten it up first?

Frequently Asked Questions
Most SaaS teams send one reminder three to seven days before the trial ends and a final one on the last day. If your trial needs a card up front, also tell users when they will be charged.
Replace the sample numbers with your email platform's variables, such as {{ customer.projects_count }} in Customer.io or a property in HubSpot or Intercom. If you send from your own code, insert the values when you build the email.
The end date, what the user has achieved, the plan and price that fits them, one clear upgrade button, and what happens if they don't upgrade. This template includes all of them.
It is usually treated as marketing, because its main purpose is to sell a subscription, so it includes an unsubscribe link. A pure billing notice, such as "your card will be charged on Friday", is transactional.
Yes. The card is a table with a coloured border, and the features are simple paragraphs with check marks, which Outlook's Word-based renderer handles reliably. Rounded corners are square in Outlook for Windows, which doesn't affect the layout.
It saves an editable copy of your Trial Ending Email in My Code, the UI Snippets code editor: the email markup goes in the HTML panel and its CSS (mobile and dark-mode rules plus fonts) in the CSS panel, so you can keep refining the code and save your own versions.
It is a Patreon template. Anyone can preview and edit it for free. Exporting and forking it are for Patreon supporters ($5 a month), who enter the supporter passcode once; designs you make with it can then be used in personal and commercial work. Everything runs in your browser, and your edits are saved locally.
