Transactional emails for SaaS, built and tested
12 tested, dark-mode-ready transactional email templates (welcome, receipts, password reset and more) in MJML and Handlebars, with plain-text versions and a test report you can rerun.
What you get
12 lifecycle emails
Welcome, verify email, magic link, password reset and changed, receipt, payment failed, trial ending, cancellation, team invite, usage alert, account deleted.
Works with your sender
Handlebars variables work with Postmark, SendGrid, Resend, Amazon SES, Mailgun or your own code. Sending examples are included.
Tested, with the evidence
An automated suite checks size (under Gmail's 102 KB clip limit), alt text, lang, preheaders, link safety, unresolved variables, 375px overflow and WCAG AA contrast in light and dark mode. Rerun it after you edit.
Plain text included
Each email has a readable plain-text version for better deliverability and accessibility.
One theme file
Change colours, logo and address in theme.json, edit copy in templates.js, then run one build command.
No trackers or web fonts
System font stack, no external CSS, no tracking pixels.
What we haven't tested
The screenshots come from headless Chrome. We haven't tested in Outlook desktop's Word engine, the Gmail apps or Apple Mail. The markup is MJML's Outlook-safe output with MSO conditionals, but run a test in your own client mix before you rely on it.
Pricing
One-off payment, with free v1.x updates. Prices in GBP; no VAT is charged (we are not VAT-registered). For UK customers and for businesses outside the UK. EU/EEA consumers can't buy.

FAQ
What will appear on my card statement?
Payments are processed by Stripe. Until our payment descriptor is updated, your statement may show MEGAWATTIQ.AI (possibly followed by LETTERBENCH). That's us. Your Stripe receipt names the Letterbench Transactional Email Kit.
How do I get the files?
Straight after payment you're taken to the download page. Bookmark it. If you lose it, use the contact form with your receipt number and we'll send it again.
Is there a free version?
Yes. Letterbench Lite (welcome, verify email, password reset) is MIT-licensed. Download it free.
Which email providers does it work with?
Any provider that accepts HTML, or that renders Handlebars templates (SendGrid dynamic templates, Postmark, SES, Resend via Handlebars). Examples are included.
Do you support Outlook?
The HTML uses MJML's Outlook-safe output, including VML/MSO conditionals. We haven't tested in Outlook desktop itself. The test report says exactly what's covered.
Who can buy?
UK customers (businesses and individuals) and businesses outside the UK that enter their VAT or tax ID at checkout. To keep things simple on tax, we don't sell to consumers in the EU or EEA. Non-UK orders without a business tax ID are refunded.
Refunds?
If the kit doesn't work for you, ask within 14 days for a full refund. No questions asked.
VAT and invoices
We're not VAT-registered, so no VAT is charged. Your Stripe receipt is your proof of purchase.
Can I use it in client projects?
Solo covers one product or company. Agencies building for several clients need the Team licence for each client organisation. Reselling the templates as templates isn't allowed.
